Understanding 4 Wheel Drive
What is 4 Wheel Drive?
4 Wheel Drive (4WD) is a system that delivers power to all four vehicle wheels. This system provides better traction and stability on slippery or uneven surfaces, making it ideal for off-road driving. Unlike a 2WD system, where only two wheels receive power, a 4WD system sends power to all four wheels, allowing the vehicle to move through tough terrain.
Why Use 4 Wheel Drive?
4WD is essential for off-road driving but can also be useful in other situations. For example, if you are driving on a wet or icy road, 4WD can improve traction and help you maintain vehicle control. Additionally, if you are driving on steep hills or towing a heavy load, 4WD can provide the extra power you need to do the job.
Types of 4 Wheel Drive Systems
There are two main types of 4WD systems: part-time and full-time. Part-time 4WD systems are designed for off-road use and are not meant to be used on dry pavement. Depending on the driving conditions, these systems allow the driver to switch between 2WD and 4WD modes. Full-time 4WD systems, on the other hand, are designed for on-road use and provide constant power to all four wheels. These systems are ideal for drivers frequently encountering slippery or uneven road conditions.
It’s important to note that not all 4WD systems are created equal. Some systems are more advanced than others and offer additional features like differential locks, which can improve traction even further. When using 4WD, it’s important to understand your vehicle’s capabilities and use the system appropriately to avoid damaging your vehicle or getting stuck in a difficult situation.

Using 4 Wheel Drive on Jeep Wrangler
Jeep Wrangler is a popular off-road vehicle with a 4 wheel drive system. The 4 wheel drive system is an essential feature that helps the vehicle navigate rough terrains and challenging weather conditions.
Driving in 4H
Driving in 4H (4 High) is suitable for off-road conditions such as snow, mud, sand, and loose gravel. To engage 4H, the Jeep must move at less than 55 mph. Here are the steps to engage 4H:
- Slow down the Jeep to a crawl and shift from drive into neutral.
- While still rolling forward, push the transfer case shift lever up into 4-high.
- Once that is accomplished, put the Jeep back into gear and slide the transfer case handle up into 4H.
When driving in 4H, keeping the speed below 55 mph is essential to avoid damaging the transfer case. Also, avoid driving on dry pavement in 4H, which can cause drivetrain binding and damage.
Driving in 4L
Driving in 4L (4 Low) is suitable for steep inclines, rock crawling, and deep mud. To engage 4L, follow these steps:
- Apply the brake pedal and move the gear selector to Neutral (N).
- Release the brake pedal and let the Jeep coast at a low speed, possibly two or three miles per hour (without applying the gas pedal).
- Move the 4WD selector from 4H to 4L quickly, and don’t pause in the Neutral position between the two gears.
- Once the 4L is engaged, put the Jeep back into gear and start driving.
When driving in 4L, it’s essential to keep the speed low and avoid sudden movements to prevent damage to the vehicle.
Disengaging 4 Wheel Drive
When it’s time to disengage the 4 wheel drive system, follow these steps:
- Slow down the Jeep to a crawl and shift from drive into neutral.
- While still rolling forward, push the transfer case shift lever down into 2-high.
- Once that is accomplished, put the Jeep back into gear, and the 4 wheel drive system will be disengaged.
Tips for Using 4 Wheel Drive on Jeep Wrangler
When to Use 4 Wheel Drive
Jeep Wrangler’s 4 Wheel Drive (4WD) system is designed to provide better traction and stability when driving on slippery or uneven terrain. Here are some situations when you should engage 4WD on your Jeep Wrangler:
- Driving on snow, ice, mud, sand, or gravel
- Climbing steep hills or rocky terrain
- Crossing streams or rivers
- Towing heavy loads
- Driving off-road
Remember that 4WD is meant for something other than regular driving on dry, smooth roads. It can cause unnecessary wear and tear on the system and decrease fuel efficiency.
Things to Avoid in 4 Wheel Drive
While 4WD can improve your Jeep Wrangler’s performance in certain situations, there are some things you should avoid doing to prevent damage to the system:
- Don’t engage 4WD while driving at high speeds, as it can cause the system to overheat and fail.
- Don’t use 4WD on dry, smooth roads, as it can cause drivetrain binding and damage.
