Your Differential Is Essential to Creating Forward Motion with Your Vehicle

Getting the power that your engine generates translated into forward motion is a complex process involving a lot of gears. One of the most important components to this is your differential.

Your differential is essentially a gearbox that resides in the center of your axle. The power that your engine generates is sent to the transmission which is where your gearing is done. That powers the driveline that runs down the length of your vehicle. This rotates and powers your differential. As the differential turns, it sends power to the wheels so that they turn. It is geared in such a way that it is able to send different amounts of torque to each wheel simultaneously so that the vehicle can maintain its speed through a turn.

What are the Main Purposes of a Differential Axle?

The differential has three main jobs to do:

  • It sends engine power to the wheels.
  • It serves as the final gear reduction. Because of the differential transmission rotational speed is slowed.
  • It allows the tires to rotate at different speeds when sending power to the wheels.

Car Differential Problems

What are a few signs of a damaged differential? Below are some common car differential problems. You may notice the signals of a damaged differential by inspecting other components of the vehicle:

  • Broken pinion gear tooth
  • Bad wheel bearings
  • Insufficient lubrication
  • Loose pinion-bearing preload
  • Worn carrier bearings
  • Out-of-balance driveshaft

A bad differential can lead to costly repairs down the road, so if you are noticing any issues, be sure to make a service appointment as soon as possible. A damaged differential can also compromise your driving safety by locking the wheels or making it more difficult to turn.
