A differential refers to a gear train that allows the velocity of shafts to be controlled. In cars, the differential is located in the middle of the left and right axle. There are several types of differentials, such as open differentials and locking differentials. This article discusses locking differentials. Use this information to decide whether a locking differential is appropriate for your 4x4 vehicle.

Types of Locking Differentials

Locking differentials force the axles of both wheels to rotate at the same speed regardless of the traction of each wheel. Locking differentials are of two types.

The first type is the automatic locking differential. The differential automatically locks the axles once the computer of the vehicle detects that one of the axles is losing traction. The differential then unlocks once traction improves. This type of differential is the most affordable of the locking differentials. However, it makes driving your vehicle on streets uncomfortable because the differential can keep engaging and disengaging as you drive. This is because the vehicle keeps jerking as the differential is engaged.

The second type of locking differential is the selectable locking differential. It is activated when the driver presses a switch after detecting that one of the axles is losing traction. After the axle regains traction, the driver disengages the differential by turning the switch to the off position. This mechanism makes this type of differential good for driving your 4x4 on the street, since the differential can remain disengaged during the drive.

The Advantages of Locking Differentials

The biggest advantage of locking differentials is that the acceleration of your vehicle will be uniform as you drive in challenging situations, such as through mud.

You may also use less fuel when driving on streets because the differential will be unlocked. This will remove the added load that the engine has to carry when providing extra power to make wheels with differing traction to rotate at the same pace.

The Disadvantages of Locking Differentials

Automatic locking differentials can be very noisy when engaged. This discomfort is also present to a limited degree in selectable locking differentials. This is because selectable ones are engaged less frequently than the automatic ones.

Locking differentials may also stress axles and shafts excessively as they force them to rotate uniformly. This can at times cause an axle shaft to snap.

Think carefully about the issues above before you select a type of differential to install in your vehicle. It may also be helpful for you to discuss the other types of differentials with a professional before you make a final choice.
