How 4x4 Systems WorkRock-Trac® * The Rock-Trac transfer case is the heart of Wrangler Rubicon's extreme rock crawling ability. Because of the 4:1 low-gear ratio, Rock-Trac's low crawl speed makes it easy to ascend or descend sharp inclines and to crawl over obstacles. Standard on: Wrangler Rubicon and Wrangler Unlimited Rubicon.Command-Trac ™ * This legendary part-time system has served Jeep® owners well through the years. Command-Trac is a proven shift-on-the-fly system with 2.72:1 Low-Range and Neutral. Standard on: Wrangler Sport, Wrangler Sahara, Wrangler Unlimited Sport and Wrangler Unlimited Sahara.Command-Trac II™ * Command-Trac II supports a two-speed, part-time four-wheel-drive transfer case. 2WD is the usual driving mode, with the front driveline disengaged from the transfer case and power directed to the rear wheels. * Selecting 4WD Lock via the electronic, console-mounted switch, locks the front and rear driveshafts together; the two then rotate at the same speed and provide a 50 front/50 rear torque split, providing better traction on slippery surfaces. This transfer case allows for 2WD, 4WD high-range and low-range as well as neutral. Standard on all Liberty models.Selec-Trac II™ * Selec-Trac II™ supports a two-speed, full-time active "on-demand" four-wheel-drive transfer case. When driving in 4WD Auto mode, the transfer case clutch pack can detect wheel slippage and instantly apply increased or decreased torque between the front and rear axles based on real-time driving conditions, thus optimizing traction. * Under the right conditions, the vehicle can be driven by just one wheel. For added capability when traversing steep grades, rough terrain, or extremely poor traction surfaces, the transfer case includes a 4WD Low mode. Electronic shifting between 4WD Auto and 4WD Low is accomplished via a console-mounted switch. A 2WD mode is also provided. Optional on all Liberty models.Quadra-Drive II™ * Quadra-Drive II's active full-time 4WD system is the ultimate for virtually any driving situation. This system uses the Quadra-Trac II transfer case and Electronic Limited Slip Differentials in both axles, offering excellent tractive performance. Quadra-Drive II also features 2.72 LOW-RANGE and NEUTRAL. Optional on Grand Cherokee North Edition/Limited, Commander Sport/Limited.Quadra-Trac I™ * The brilliance of this 4WD system is its simplicity. Quadra-Trac I operates in a high-range, all-time mode delivering optimum traction in virtually any driving situation with no driver input required. * NOTE: The Grand Cherokee SRT8 uses an on-demand system that drives the rear driveshaft and engages the front driveshaft when needed, either when slip is sensed, or with throttle anticipation, which engages the front prior to slip when throttle is applied. Standard on: Grand Cherokee North Edition/Limited and Commander Sport.Quadra-Trac II™ * This active full-time system functions in all-wheel drive until additional traction is needed, then reacts by electronically engaging the clutch pack to transfer up to 100% of the torque to either axle. This system also features 2.72:1 LOW-RANGE and NEUTRAL. Standard on: Commander Limited. Optional on: Grand Cherokee North Edition, Limited and Commander Sport.Freedom-Drive I™ * Jeep Compass 4x4 models with a five-speed manual transmission or Continuously Variable Transmission feature standard Freedom-Drive I. This state-of-the-art electronic system anticipates the need for added traction and responds to wheel slippage or accelerator pedal position by transferring power to the rear wheels, while modulating rear wheels to contribute to vehicle stability in cornering situations. * The system also saves fuel by operating only on demand when on-road, thereby minimizing power-robbing friction and inertia. A 4WD LOCK mode, providing a locked 50/50 torque split between front and rear at low speeds for severe road or trail conditions is activated by pulling up on the chrome T-handle switch labelled 4WD LOCK in the centre console. Standard on Compass and Patriot 4x4.Freedom-Drive II™ * An electronically controlled coupling, forward of the rear differential, is the heart of the Freedom-Drive I and II systems. The electronic control module processes signals from the wheel speed sensors and the accelerator pedal to determine how much torque to transfer to the rear wheels, then sends an electrical current to the ECC that is proportional to the amount of torque required. * A 4WD LOCK mode, providing a locked 50/50 torque split between front and rear (at low speeds) for severe road or trail conditions is activated with a T-handle switch labelled 4WD LOCK in the centre console. Recommended for true off-road situations including steep grades, wheel lift and rock or log climbing, the Freedom-Drive II Off-Road Package includes a second-generation Continuously Variable Transmission (CVT2L) with a 19:1 crawl ratio that engages when the off-road mode is activated. Optional, with the Trail Rated Off-Road Group on Patriot 4x4.

Off-Road Driving GuideBe Prepared * Always check your vehicle before going off-road. Make sure your battery is fastened, all hoses are in good condition and oil and fluids are topped off, including fuel. Also be sure that all four tires are in good condition and have the proper tire pressure. Avoid travelling alone, especially into unfamiliar territory. Even with a caravan of two, there's always a tow vehicle.Be on the Lookout * Once off-road, put your vehicle in 4WD whenever you anticipate a situation that will demand the additional traction. It's difficult to engage 4WD after you get stuck. You'll also want to get into the habit of looking over your hood, scanning left to right so you can clearly see what you're approaching on the trail. If you're just watching the left tire, there's a good chance you'll get the right tire in trouble. Avoid putting your head outside the vehicle to see what's coming (that's what Wrangler's folding windshield is for!). * Also, many trail masters recommend keeping your thumbs up and out of the way of the steering wheel spokes in rough terrain. For example, if your tire suddenly falls off a rock, your steering wheel could quickly rotate and catch your thumb with a spoke - ouch! Generally, vehicles with power steering, like all Jeep® vehicles, lessen the chance of sudden steering wheel rotation.Take It easy * Speed and power are not required in rough off-road driving. In low-range 4WD, the low gearing and low speed of Jeep® vehicles at idle will generally pull you over obstacles. In many cases, with manual transmissions, letting the clutch out slowly and allowing the vehicle to crawl over obstacles in the lowest gear is the best scenario. As a matter of fact, on the Rubicon Trail, the average speed is a mere 5 to 8 km/h (3-5 miles per hour).Snow and Mud * Generally, when snow or mud is present on the driving surface, it is the right time to engage your on-demand or part-time 4WD system. If you have an all-time system like Quadra-Trac I™, there is no input required from you. In heavy snow, when pulling a load, or for additional control at slower speeds, shift the transmission to a low gear and shift the transfer case to 4-LO if necessary (Quadra-Trac I does not offer a low range). * Don't shift to a lower gear than necessary to maintain momentum. Over-revving the engine can spin the wheels and traction will be lost. If you begin to lose traction in snow or mud, turn your steering wheel back and forth rapidly. This will generally help the wheels bite into fresh terrain and pull you through. If traction is lost and the vehicle stops do not spin your wheels, it will just dig you in deeper. The key is to maintain forward momentum.Sand * For better traction in sand, drop air pressure 10-12 pounds below normal pressure on conventional tires. (Return to normal pressure after use in these conditions). Try high-range 4WD to maintain forward momentum. Depending on the condition of the sand, low-range 4WD and alternative gear selections may be necessary. Also try to make wider turns if at all possible. Tight turning slows the vehicle abruptly and can get you stuck. Again, maintaining forward momentum is key.Hills * When climbing hills ALWAYS go straight up or down. It's also smart to know what's on the other side before going up. At the base of the hill you should apply more power. Ease up on the power as you approach the top and before going over the crest. If you stall on the ascent, back straight down the hill in reverse. For downhill travel, always use the lowest gear with a manual transmission. * When descending a hill in low-range, do not disengage the clutch and allow the vehicle to coast. Severe damage to your clutch disc may result. Allow the gears and engine compression to slow you down, using the brakes only to fine-tune your speed. If equipped with an automatic transmission, use low-range and the lowest drive setting. NOTE: NEVER drive a hill at an angle. If the hill is very steep and you don't feel confident that you or your vehicle can make it up, then don't attempt it.Rock Crawling * Always check your vehicle before going off-road. Make sure your battery is fastened, all hoses are in good condition and oil and fluids are topped off, including fuel. Also be sure that all four tires are in good condition and have the proper tire pressure. Avoid travelling alone, especially into unfamiliar territory.

If the hill is very steep and you don't feel confident that you or your vehicle can make it up, then don't attempt it.Tread Lightly * Leave it better than you found it. Observe posted signs and stay on trails and recreation areas approved for off-roading. Use your good judgment in protecting the beauty and solitude of the area. Don't leave anything behind and, better yet, pick up and remove any trash that others have discarded. And if the terrain looks especially fragile, take an alternate route.

Trail Rated CertificationOverview * From the original Willys MB to the 2009 Liberty, the Jeep® brand has been the leader in 4x4 innovation and off-road capability for over 67 years. The proof is in our exclusive Trail Rated® standard. * We test Jeep 4x4s on the toughest trails in the world to prove one thing: They can take whatever you dish out. The Trail Rated badge means that your Jeep 4x4 has been designed to perform in five categories of off-road conditions: traction, ground clearance, manoeuvrability, articulation, and water fording.Traction * Traction in 4x4 is equivalent to grip on asphalt. Trail Rated traction helps you stay in control on untamed terrain, slippery (wet, mud, snow) conditions, and on steep grades.Ground Clearance * Don't drag your belly through the mud - just clear nasty logs, rocks, and uneven ground without sustaining undercarriage damage. Jeep® Trail Rated 4x4s feature optimized approach, departure, and breakover angles to keep you in the clear.Manoeuvrability * Athletic. Agile. Trail Rated. Jeep® 4x4s have the footwork to navigate narrow gaps, dodge emergency situations and avoid cosmetic damage to underbody sills thanks to precision steering and optimized wheelbases. Even gazelles don't move like this.Articulation * A Trail Rated suspension is limber like a gymnast. How exactly? Flexibility is the key to good articulation. The more a wheel can travel, or flex, the better it can maintain contact with terra firma and provide the traction needed to cross an array of obstacles.Water Fording * Hit that riverbed with confidence. Trail Rated Jeep® 4x4s feature additional electrical and body sealing, along with a high air intake location for optimum water fording capability. Note: Do not attempt water fording unless depth is known to be less than 50 cm (20 inches).

FAQWhat is the difference between Full-Time 4WD and Part-Time 4WD systems?Full-Time 4WD systems utilize a centre differential, which enables the front and rear driveshafts to turn at different speeds, thereby allowing engagement on dry surfaces for normal driving conditions. A Part-Time system does not employ a centre differential and locks the front and rear driveshafts together. With a Part-Time system, 2WD mode should be used during normal driving conditions and 4WD mode is to be used only when off-road or on wet or slippery surfaces.Why can't you use Part-Time 4WD on dry surfaces?Part-Time 4WD systems effectively lock the front and rear driveshafts together, forming a single driving unit that does not allow for differential action between the front and rear driveshafts. Driveline noise and binding (Crow Hop) may occur when operated excessively on dry surfaces or in turns. This binding can lead to heat buildup and early part failure.Why does Crow Hop occur?When a vehicle turns, each wheel rotates on a different radius to the turning circle, thus travelling at different distances and speeds. If the vehicle's front and rear axles are locked together and are turning on dry surfaces, the difference in wheel speed sometimes results in driveline binding that is released with a bang or vehicle shudder when one of the tires loses traction.Can I shift into 4WD High Range at any speed?Shifting into 4WD High Range can be made with the vehicle stopped or in motion. If the vehicle is in motion, shifts can be made up to 88 km/h (55 mph).How long can I drive in 4WD High Range?With a Part-Time system, prolonged driving in 4WD High Range is recommended only for wet, loose, or slippery road surfaces. With a Full-Time system, you need not worry about switching to 2WD mode when road surfaces improve.How fast can I drive in 4WD High Range?You should not go faster than road conditions permit.What is 4WD Low Range?4WD Low Range is a mode specifically designed for temporary use when additional traction and maximum pulling power is desired. Front and rear driveshafts are locked together and engine power is sent through another set of gears to multiply torque. Avoid attempting to engage or disengage Low Range with the vehicle moving faster than 3 to 5 km/h (2 to 3 mph) and do not use this mode for normal driving.Can I shift into 4WD Low Range at any speed?No. With the vehicle rolling at 3 to 5 km/h (2 to 3 mph), shift an automatic transmission to Neutral or depress the clutch pedal on a manual transmission. While the vehicle is coasting at 3 to 5 km/h (2 to 3 mph), shift the transfer case lever firmly through Neutral and into the Low Range position.How fast can I drive in 4WD Low Range?Do not exceed 40 km/h (25 mph).Can I shift into 4WD Low Range when stopped?Shifting into or out of 4WD Low Range is possible with the vehicle completely stopped, however, difficulty may occur due to the teeth of the gears not being properly aligned. Several attempts may be required for clutch teeth alignment and shift completion to occur. The preferred method is with the vehicle rolling at 3 to 5 km/h (2 to 3 mph). Avoid attempting to engage or disengage 4 Low Range with the vehicle moving faster than 3 to 5 km/h (2 to 3 mph).

GLOSSARYApproach AngleStarting from level ground, this is the degree of slope a vehicle can approach without scraping or hitting the front undercarriage. It's a great indication of the ability to navigate severe off-road terrain like boulders and logs. A short front overhang produces high angles of approach, thus increasing off-road ability.ArticulationA Trail Rated® suspension is limber like a gymnast. How exactly? Flexibility is the key to good articulation. The more a wheel can travel, or flex, the better it can maintain contact with terra firma and provide the traction needed to cross an array of obstacles.Axle ArticulationThe ability of one axle to move relative to the chassis. It is the measure of the ease with which tires stay in contact with the ground (and retain traction) on very uneven terrain.Axle DifferentialAn axle differential is a gear system located in the centre housing of an axle assembly designed to allow the wheels to rotate at different speeds during cornering.AxleOriginally the term used only for a rigid piece of metal that connects the front and/or rear wheels together. The suspension components attach to the axle and to the vehicle's body frame. However the term is now often used for a front or rear drive system where the "axle" is not a solid beam, but instead comprises articulating left and right "axle" or "drive" shafts combined with an independent suspension. The advantage of the solid beam axle is that is provides additional ground clearance when one wheel rides up over an obstacle.Brake Traction Control SystemTransfers torque from one wheel to another on the same axle when wheel slip conditions are detected.Breakover AngleThe degree of slope that defines the largest ramp or hill that a vehicle can travel over without scraping against the frame or underbody components.Centre Differential – GearedA gear system located inside the transfer case of full-time 4WD vehicles. It is used to distribute drive torque to the front and rear driveshafts and allows the front and rear wheels to rotate at different speeds during cornering.Clutch PlatesA series of alternating steel plates within the transfer case of many on-demand or automatic 4WD systems. One set of plates is splined to the clutch assembly hub of the rear driveshaft; the other set is splined to the clutch drum attached to the front driveshaft. The clutch housing is usually filled with a viscous, silicone-type fluid that clings to the discs to help transfer torque to the driveshaft. The engagement of clutch plates can also be controlled electronically.Coil SpringsA coil of flexible metal that can be compressed or stretched along its centreline axis without permanent deformation. Coil springs support the weight of the vehicle while allowing the wheels to travel up and down over bumps.Continuously Variable TransmissionA stepless transmission that operates by varying the working diameters of two pulleys, transmitting torque by means of an immensley strong steel-segmented push-belt.Crawl RatioEssential for serious off-road treks involving steep hill climbs and descents, this is the final drive ratio of a vehicle in low-range. It allows Jeep® vehicles to ìcreepî along (without depressing the accelerator) at very low speeds. Essentially, the vehicle does all the work. Except with Freedom-Drive II® on Patriot, crawl ratio is determined by this formula: first gear ratio x rear axle ratio x low-range 4WD ratio. The higher the number, the better the off-road capabilities. With Freedom-Drive II on Patriot, crawl ratio is a special fixed CVT ratio of 19:1.Crow-HopeVehicle shudder and tire scuffing due to a binding condition in the driveline. Usually caused by operating in basic 4WD or part-time 4WD modes on dry pavement.Departure AngleWhen returning to level ground from a descent, this angle indicates the degree of a slope from which a vehicle can depart without scraping or hitting the rear undercarriage.DifferentialA gear system that transmits torque to the drive wheels, while also allowing the wheels to rotate at different speeds when cornering. 4WD vehicles have differentials in both the front and rear axles.DriveshaftShaft connecting the transmission output shaft to the differential drive pinion shaft. Four-wheel-drive vehicles add a second driveshaft from the transfer case to the front differential. Sometimes also used for the left and right ""axle"" shafts on a vehicle with front or rear independent suspension.Electronically Controlled CouplingManages the torque split from front to rear with no active driver input needed for smooth and automatic performance. Only on Compass or Patriot 4x4 with Freedom-Drive I® or Freedom-Drive II®, it responds to throttle position or to front wheel slippage.Fixed Yoke Output AssemblyEffectively handles the extra output from the transfer case and helps to ensure smooth and durable driveline operation.Four-Wheel DriveA drivetrain that utilizes a transfer case or Electronically Controlled Coupling to distribute engine power between the front and rear axles in order to drive all four wheels. Full-time four-wheel-drive systems utilize a centre differential, which enables the front and rear driveshafts to turn at different speeds, thereby allowing engagement on dry pavement for normal driving conditions. A part-time system does not employ a centre differential and, during normal driving conditions, must operate only in two-wheel drive. With a part-time system, the four-wheel-drive mode is to be used only when off-road or on wet or slippery surfaces.Front Axle DisconnectA mechanical or vacuum-operated component used primarily on four-wheel-drive models to connect and disconnect drive torque to the front axle. When shifting from four-wheel drive to two-wheel drive, this system disengages the front axle from the front driveline, so that the front wheels aren't turning the front driveline unnecessarily. This reduces unnecessary front driveline wear, noise and fuel consumption.Gerotor CouplingA speed-sensing component used in four-wheel-drive systems, which includes a fluid pump, a piston and a set of clutch plates. When a speed difference occurs between the front and rear driveshafts of the vehicle (as when a wheel loses traction), the gerotor pump in the transfer case supplies instantaneous pressure to the clutch plates that transfer torque to the axle where the wheels have more traction. This coupling is smaller, lighter and faster acting than conventional four-wheel-drive power-transferring components.Ground ClearanceDon't drag your belly through the mud - just clear nasty logs, rocks, and uneven ground without sustaining undercarriage damage. Jeep® Trail Rated® 4x4s feature optimized approach, departure, and breakover angles to keep you in the clear.High-RangeA 4WD mode used for on-road or light off-road use.Hill Descent ControlThis system uses the ABS braking to control the car's motion downhill. Also allows a smooth and controlled hill descent in rough terrain without the driver needing to touch the brake pedal. If the vehicle accelerates without the driver input, the system will automatically apply the brakes to slow down to the desired vehicle speed.Jounce/ReboundThe motion of a wheel that compresses its suspension. If a wheel is at full jounce, it is at the upper limits of its travel. The opposite of jounce is rebound ó or wheel movement that decompresses a vehicle's suspension.Limited-Slip DifferentialProvides the same basic functions as an axle differential, but with an added advantage: when the drive wheel begins spinning as a result of being on a slippery surface, a limited-slip differential automatically transfers torque to the opposite wheel to help improve traction. On some vehicles the same effect is achieved by using electronic sensors and controls to apply the brake at a wheel that is starting to spin.Locking DifferentialProvides even more traction than a limited-slip differential by ìlockingî the axle shafts together when the driver wants to do it. Locking differentials do not allow for wheel-speed differences and must not be used on dry, paved roads.Low Crawl SpeedThe ìcrawl ratioî is the lowest gear ratio in a vehicle and is determined by multiplying the first gear ratio times the low-range ratio times the axle ratio.Low-RangeA 4WD mode used for severe off-road conditions.ManoeuvrabilityAthletic. Agile. Trail Rated®. Jeep® 4x4s have the footwork to navigate narrow gaps, dodge emergency situations and avoid cosmetic damage to underbody sills thanks to precision steering and optimized wheelbases. Even gazelles don't move like this.NeutralWhen the shifter is in this position, the front and rear axles spin freely. Sometimes used for towing a Jeep® vehicle behind another vehicle (such as a motor home), so that uncoupling the driveshafts is not required. Also used in the process of shifting into 4-Low.Open-Centre DifferentialLocated in the transfer case on some full-time four-wheel-drive vehicles, this component works in the same way as an open differential in the axles, but is of a more compact design. This component employs a planetary gearset, with planetary gears that revolve around the sun gear and inside the ring gear.Power Robbing FrictionSurface resistance to relative motion, as of a body sliding or rolling.Progressive AxleProgressive front and rear axles transfer torque side to side in search of the wheel with the greater traction. This mechanical (gerotor pump) system transfers torque relative to differences in wheel speed rather than torque difference. The end result is a system that can deliver far more torque to the wheel that needs it than conventional limited-slip differential systems.Running Ground ClearanceThe distance from the ground to the lowest point between the axles.Shift-on-the-FlyThe ability to shift from two-wheel drive to four-wheel drive while the vehicle is moving.Skid PlateHelps protect the undercarriage from damage when driving off-road.Solid Axle/Coil SpringsIdeal off-road equipment. Instead of each wheel on an axle being sprung separately (like independent suspension designs), a solid axle connects the suspension of two wheels. Coil springs then support the vehicle's weight and allow the wheels to travel up and down over terrain.Suspension TravelFrom full jounce to full rebound, this is the amount of vertical wheel movement allowed by the suspension.Tow HooksHeavy-duty forged steel hooks in the front and rear of a vehicle that provide attachment points for snatch-em straps and winch cables (see the Off-Road Driving Tips section) should you get stuck.TractionTraction in 4x4 is equivalent to grip on asphalt. Trail Rated® traction helps you stay in control on untamed terrain, slippery (wet, mud, snow) conditions, and on steep grades.Transfer CaseMounted behind and driven by the transmission on most 4x4 vehicles, the transfer case transmits power to the front and rear driveshafts in 4WD Jeep® vehicles and offers high and low range. For the full line of Jeep transfer cases see the Get Ready section. Compass and Patriot 4x4 use an Electronically Controlled Coupling instead of a traditional transfer case.TransmissionA mechanism that transfers torque into usable driving power usually through the use of gearsets. These gearsets multiply engine torque in varying amounts to meet specific driving demands. An exception is a Continuously Variable Transmission (CVT), available on Compass and Patriot, which instead operates by varying the working diameters of two pulleys, transmitting torque by means of an immensely strong, steel-segmented push-belt.Two-Wheel DriveWhen the shifter is in this position, the front axle spins freely while power is sent to the rear axle and wheels, which then drive the vehicle.Viscous CouplingA speed-sensitive device located in the transfer case that transmits drive torque between the front and rear driveshafts when wheel-slip occurs. Viscous couplings are typically used on all-wheel-drive vehicles and vehicles with automatic and on-demand four-wheel-drive systems.
