When you’re shopping for an off-road vehicle, like one of the models from a Jeep dealership in Miami, it’s important to understand the basics of four-wheel drive.

Knowing what each system is best used for and comparing that to your driving needs can help you find the right model for you.

Part-Time or Full-Time?

A part-time 4WD system locks the front and rear driveshafts together, and it doesn’t allow the wheels on either end to turn at different speeds. This can be beneficial in an off-road situation, but should not be used on the road.

If it is used for regular driving, it can cause serious mechanical problems. That’s why it’s important to remember to turn it off when you’re not actively using it.

A full-time 4WD system employs a center differential to allow for regular street driving, as well as off-roading. It engages all four wheels all of the time, sending them torque as needed.

What is Low-Range?

4WD low-range is intended for use in situations that require increased traction. You would use this setting when you’re dealing with deep sand, mud, or large rocks.

When you use the low-range, you should also remain at a low speed. Then more torque will go to your wheels to help you grip better.

You typically don’t want to go any faster than about 40 miles per hour. The idea is to move slowly and use the extra power going to the wheels to overcome obstacles.

What is High-Range?

4WD high-range is a good choice for moderate terrain that requires added grip but isn’t too intense.

It helps prevent slippage and wheel spinning.

When you’re working with a part-time 4WD system, you should only use high-range if the ground is really slick or uneven. Switch back when you have finished traversing that area.

If you have a full-time system, you don’t have to worry about switching; it automatically adjusts.

Make sure that whenever you’re using the high-range setting, you watch your speed and match it to the terrain you’re traveling on.
