The Jeep Wrangler is an iconic automobile that’s identified for its off-road capabilities. One of the vital essential options of the Wrangler is its four-wheel drive system. Whereas four-wheel drive just isn’t vital for every type of off-roading, it may be a lifesaver when you’re confronted with difficult terrain. If you’re new to driving a Jeep Wrangler, it is very important know how you can correctly interact the four-wheel drive system.
There are three kinds of four-wheel drive techniques out there on the Jeep Wrangler: Command-Trac, Selec-Trac, and Rock-Trac. The Command-Trac system is essentially the most fundamental and is discovered on the Sport and Sahara fashions. The Selec-Trac system is obtainable on the Rubicon mannequin and means that you can select between two-wheel drive, four-wheel drive excessive, and four-wheel drive low. The Rock-Trac system is essentially the most superior and is discovered on the Rubicon Rubicon mannequin. It incorporates a low-range switch case that gives extra torque for crawling over rocks and different obstacles.
Irrespective of which four-wheel drive system you will have, the method of participating it’s the identical. First, cease the automobile and shift the transmission into impartial. Then, pull the four-wheel drive lever into the specified place. The lever is situated on the middle console, subsequent to the shifter. As soon as the lever is within the desired place, begin the automobile and drive slowly. You must really feel the automobile interact four-wheel drive as you drive. If you don’t really feel the automobile interact, cease and check out once more.
Have interaction the Switch Case
To interact the switch case in a Jeep Wrangler, observe these steps:
1. Make sure the Automobile is Secure to Have interaction
- Be sure that the automobile is parked on a stage floor.
- Place the transmission in impartial.
- Set the parking brake.
- Flip the engine off.
| Switch Case Mannequin | Lever Place for 4WD Excessive |
|---|---|
| Command-Trac | “4 HI” (label on lever) |
| Selec-Trac | “N” (impartial) to “4 HI” |
| Rock-Trac | “N” (impartial) to “4 HI” |
2. Find the Switch Case Lever
The switch case lever is usually situated on the ground of the automobile, between the driving force and passenger seats.
3. Shift the Lever to 4WD Excessive
Transfer the switch case lever to the “4 HI” place. On some fashions, chances are you’ll want to tug up or push down on the lever to have interaction it.

The switch case lever means that you can swap between 2WD (two-wheel drive), 4WD (four-wheel drive), and different modes relying on the precise Jeep mannequin.
3. Partaking 4WD
To interact 4WD, pull the switch case lever in the direction of you and shift it into the “4H” place for high-range four-wheel drive. This mode is appropriate for many off-road conditions, reminiscent of dust roads, gravel, and lightweight snow. In the event you encounter more difficult terrain, reminiscent of steep slopes or deep mud, you’ll be able to shift into “4L” place for low-range four-wheel drive. 4L supplies elevated torque and management for demanding situations.
Here is a desk summarizing the 4WD modes:
| 4WD Mode | Use |
|---|---|
| 2WD | Common driving situations (on-road) |
| 4H | Off-road situations (dust, gravel, mild snow) |
| 4L | Difficult off-road situations (steep slopes, deep mud) |
Please observe that shifting into 4WD whereas the automobile is in movement just isn’t really useful, as it will probably harm the drivetrain. All the time come to a whole cease earlier than participating or disengaging 4WD.
Lock the Hubs
Locking the hubs is essential for participating 4-wheel drive successfully. Here is an in depth information to locking the hubs on a Jeep Wrangler:
Auto-Locking Hubs:
