What is the purpose of differential seals?

In order to turn properly, your car’s wheels must be able to turn at different speeds. This is because the outer wheel travels a further distance than the inner wheel while turning. A differential is a mechanical device which allows a pair of wheels to rotate at different speeds.

Surrounding the differential are several seals. Their job is to seal the axle shafts against the differential and prevent differential fluid from leaking. If differential fluid leaks, the inner parts of the differential will not be lubricated properly. As a result, the differential will be subject to increased wear.

Differential seals are usually made out of heavy-duty rubber. This means that they generally last for a long time. However, they will eventually need replacement, especially in vehicles with higher mileage.


Symptoms of damaged differential seals:

There are several signs that your differential seal may be damaged, including:

  1. Leaking gear oil: One of the most obvious signs of a damaged differential seal is a leak of gear oil. This can be seen as a puddle of oil under your vehicle, especially after it has been parked for an extended period of time.
  2. Whining or humming noises: A damaged differential seal can cause a whining or humming noise while driving, especially when turning. This can be caused by the gear oil leaking out and causing friction on the gears.
  3. Vibrations: A damaged differential seal can also cause vibrations while driving, especially at higher speeds.
  4. Reduced power to the wheels: A damaged differential seal can cause a reduction in power to the wheels, resulting in a loss of traction and difficulty accelerating.
  5. Grinding or clunking noises: A damaged differential seal can also cause grinding or clunking noises, caused by the gears not being lubricated properly.

It is important to note that these symptoms can also be caused by other issues and not only differential seal, so it is recommended to have a mechanic check the vehicle for a proper diagnosis.


Is it safe to drive with a leaking differential?

If the differential has leaked a lot, it may make your vehicle unsafe to drive. This is because damage to the differential can affect your vehicle’s ability to turn. The gears inside the differential will also produce a lot of heat, which can lead to expensive damage.
