Q: Rear differential noise

asked by on

The rear differential is leaking from the pinion seal and makes noise when turn front wheels, do you think the noise is from the pinion seal?

My car has 150000 miles.
My car has an automatic transmission.

A: The noise is not coming from the pinion sea...

The noise is not coming from the pinion seal, but the pinion bearings are bad and this is why the pinion seal is leaking. You will need to have the rear end bearings and seals replaced. If you’d like to have this verified, a certified technician from YourMechanic can come to your car’s location to diagnose the squealing noise and assist with repairs.
