If you have recently purchased a Jeep Wrangler and would like to know how to engage 4-Wheel Drive then you should always consult your owner’s manual first. Each manufacture has a specific procedure to follow to safely engage 4WD without causing damage to the transmission or drivetrain. Show
You engage 4WD in a manual transmission Jeep by depressing the clutch and shifting the 4WD gear shifter into 4H. Always ensure you are not accelerating while doing so and give the 4WD shifter a firm yank to ensure it engages fully. When engaging 4L (Low Range) you need to drive as slow as 2-3 MPH. So there is nothing special or complicated about engaging the 4WD system on your jeep Wrangler manual transmission. The only difference between the manual and the auto transmission shifting procedure is depressing the clutch, and making sure you are in N(Neutral) on the auto before engaging 4-Lo. What other important factors do you need to keep in mind when shifting in 4H?

Proper Procedure to Shift into 4WD in your Manual Jeep Wrangler Before you engage 4H in your Wrangler, always ensure the terrain you are traveling is safe to do so. This means any driving conditions that have minimum traction, like:
Any of the above-mentioned surfaces are low traction surfaces and perfectly safe for you to engage 4H. When you engage 2H-4H, always ensure you are traveling no faster than 45MPH. Start by gently lifting your foot off the gas pedal and depressing the clutch while you simultaneously engage the 4WD system. Give the 4WD shifter a firm yank to engage the transfer case. Once you are in 4H, power is split 50/50 between the front and rear axles and sent to all 4 wheels. The power usually follows the line of least resistance, so when you lose traction on any given wheel, all the power on that axle will be sent to that slipping wheel. If your 4WD has traction aids, it will detect traction has been lost and brake the slipping wheel, thereby sending the power to the wheel with traction and pulling you out of a tricky, slippery situation. When you have successfully engaged 4H on your wrangler, you’ll notice an orange emblem appear on your dash. This is to indicate that all 4 wheels are powering the vehicle forward. You should never drive on a high traction surface with 4H engaged. This will result in drivetrain “binding”. Binding occurs when there is not enough slippage on the wheels, especially when turning, and all the energy is then transferred back into the drivetrain system. If driven in this state long enough, you will experience significant tire wear and eventually failure of drivetrain components.

What does this mean? Permanent 4WD is when power is constantly sent to all wheels irrespective of the driving conditions. You do not have the option to drive it in 2H by removing it from 4H. A permanent 4WD makes use of a special component called a viscous coupling that allows power to be sent to both front and rear. This component allows for varying rotational speeds which eliminates drivetrain binding. So how do you know if your Jeep has 4WD? One way to tell is by looking at the gear shifters. If you are missing a second usually smaller low-range or 4H gear shifter, you have a 2WD jeep. You can also tell by looking underneath the vehicle.

It is not uncommon for the 4H to get sticky and jammed in 4H. Try bumping it in and out of gear a few times while rolling slowly.
