  3. Replace the seal.
  4. Test the Vehicle.
  5. Inspect rear differential gasket, pinion seal, and side seal.
  6. Clean the housing.

  8. Lubricate and re-install axle into differential.

What causes a diff to whine?

Whining Sounds The most common sound of a failed differential is a whining noise. This is often due to poor lubrication within the differential, meaning there is a good chance that the differential fluid is leaking. If you spot a reddish fluid under the differential, there is certainly a leak.

What does diff backlash sound like?

While sudden, catastrophic gear failures are exceedingly rare on standard applications that are not abused, most differential failures involve whining, grinding, or rumbling noises either upon acceleration when the differential is loaded, similar noises when the vehicle is coasting, or in severe cases, a rumbling or …

Do limited slip differentials make noise?

Adding standard differential fluid to a limited-slip differential can result in noise and vibration while turning.

What does too much backlash sound like?

Conversely, a noise that is louder when the vehicle is coasting, probably means there is not enough tooth contact (too much backlash). A knocking or clicking sound may be due to the splines on the axle shafts being worn out, in which case the defective shaft has to be replaced.

Can a diff cause vibration?

When a rear differential fails, it can cause vibration, noise and fluid leaks that impact a vehicle’s acceleration and driveability. A driver should consult a certified mechanic to deal with a bad rear differential and prevent further damage to the vehicle’s driving systems.

What is diff chatter?

Chattering occurrs whenever all the oil gets squeezed out bewteen the friction surfaces and then they are forced to slip. They will chatter until some oil eventually finds its way back in there. Friction modifier prevents the oil from being squeezed all the way out.

Does your car sound like a differential gone bad?

We don’t know which sounds worse—car guys singing show tunes in the shower or a howling differential. While there is no help for our singing, we can help you diagnose the sounds coming from a differential gone bad. A clunk, whine, or howl can signal a worn-out pinion gear, bad bearings, or a faulty gear installation.

How important is differential noise diagnosis?

Diagnosing differential noise is extremely important. And while most vehicle sounds are normal while the vehicle is in motion, there are times when a noise coming from under the car can be a serious matter.

Does the noise go away when you turn left or right?

Does the noise go away when you turn (slightly) to the left or right? If so, it may be the bearing on the opposite wheel. We assume you’ve done a thorough investigation of the wheel and chassis, checking for things like loose splash shields and bent brake shrouds.
