Is locking rear differential necessary?

Four-wheel drive vehicles that drive off-road often use a locking differential to keep from getting stuck when driving on loose, muddy, or rocky terrain. Locking differentials are considered essential equipment for serious off-road driving.

What is the purpose of a diff lock?

As the name suggests, a diff-lock locks the axle so that the two wheels turn at the same speeds. Here’s an example of when this is useful: you’re driving in muddy conditions and one wheel starts to spin in deep mud while the other wheel is on firm ground.

Should I use diff lock in sand?

Having a rear differential lock, like the one in the Ford Everest 4WD, can be handy if you’re on a section of sand that’s very bumpy and is likely to cause your 4WD’s wheels to lift off the ground. An engaged rear differential lock will ensure there’s no loss of forward momentum…

Which is better limited slip or locking differential?

Limited slip differentials provide your vehicle with the best traction around. Locking differentials might give you good traction too, but the traction that you will experience with limited slip differentials is better. For starters, they will make it easier to turn on roads which are slippery and wet.

What is the advantage of a locking rear differential?

Locking differentials allow both wheels to travel at the same speed, so when traction is lost for one wheel, both wheels will still keep spinning regardless of the amount of resistance. They can be added to either the front or rear axle, or even both axles if you’re planning on doing some hardcore off-roading.

Do all 4X4 have diff lock?

It could well be that your 4X4 comes with a diff-lock on the rear axle, or on both axles. Not all versions of all 4X4s have diff-locks.

When should I lock my differential?

Use your locking differential when you want to go off road, for driving on difficult terrain, such as dirt, gravel, mud or snow. You will only need to engage your locking differential when you need extra traction, so you may only use it for a few moments on each off road adventure.

Do you use 4 High or 4 Low sand?

When to use Low: To maximize both power and traction, you can rely on low-range 4×4 for crawling over rocks, fording creeks, plowing through deep sand, or negotiating steep off-road trails. At this setting, the wheels turn more slowly than on High, so use Low only at speeds of 40 MPH or less.
