How to Put a Jeep Wrangler in 4-Wheel Drive

Jeep Wranglers are known for their rugged capability, especially when it comes to off-road environments.

One of the key features of the Wrangler is its ability to switch into 4-wheel drive (4WD), providing enhanced traction and control.

Whether you’re tackling tough terrains or facing slippery road conditions, understanding how to use the 4WD system is crucial.

This article will guide you on how to put your Jeep Wrangler in 4-wheel drive.

Step-by-Step Guide om Setting Your Jeep in a 4-Wheel Drive Mode

1. Know Your Wrangler’s 4WD System

First and foremost, it’s essential to be aware that Jeep Wranglers come with different types of 4WD systems, depending on the model and year. The most common systems are:

  • Part-Time 4WD: This is ideal for off-road or slippery conditions. It should not be used on dry pavement as it can cause damage due to the tires’ inability to slip.
  • Full-Time 4WD: Can be used all the time, including on dry roads, as it allows the front and rear axles to rotate at different speeds.

2. Locate the Transfer Case Shifter

In most Jeep Wranglers, the transfer case shifter is a separate lever located next to the main gear shifter. It’s typically shorter than the main shifter.

3. Follow the Proper Sequence

For Part-Time 4WD:

  • 2H (Two-wheel drive high range): This is your standard driving mode.
  • 4H (Four-wheel drive high range): Ideal for high-speed off-road scenarios like dirt roads, sandy areas, or snowy paved roads.
  • 4L (Four-wheel drive low range): Use this for low-speed, high-torque scenarios like rock crawling or steep inclines.

Switching to 4H:

  1. Slow down to a crawl or stop the vehicle.
  2. Firmly grip the transfer case shifter and pull it into the 4H position.
  3. You should feel the system engage. In many modern Wranglers, an indicator light on the dashboard will confirm the activation.

Switching to 4L:

  1. Bring your Wrangler to a complete stop.
  2. Place the main gear shift in neutral.
  3. Firmly pull the transfer case shifter into the 4L position.
  4. Once engaged, shift your main transmission back into gear. Use this mode at low speeds.

For Full-Time 4WD:

The process is similar, but there’s often an additional ‘4WD Auto’ or ‘4WD Full-Time’ mode which can be engaged and used on all terrains, including dry pavement.

4. Practice Safe Driving

When in 4WD, especially 4L, remember that the increased torque and traction alter your Wrangler’s driving dynamics. Turn slowly, avoid sharp maneuvers, and remember that braking distances might change.

5. Disengaging 4WD

When you’re done with 4WD:

  1. For 4H: Slow down and push the transfer case shifter back to 2H.
  2. For 4L: Stop the vehicle, shift the main transmission to neutral, then move the transfer case shifter back to 2H or 4H. Finally, put the main shifter back into gear.

6. Periodic Maintenance

If you use 4WD often, especially in taxing conditions like mud, sand, or rocks, regular maintenance is crucial. Periodically check the transfer case fluid, ensure that all components are in good working order, and listen for any unusual noises when engaging or disengaging 4WD.


Using the 4-wheel drive in your Jeep Wrangler can dramatically improve its capabilities in challenging terrains. However, it’s vital to understand how and when to use it correctly to ensure both optimal performance and safety.

Always refer to your owner’s manual for specific guidance related to your Wrangler’s model and year.
