Q: Q: Rear differential leak

asked by on

I have a rear differential leak and possibly a bad bearing.

Hello. Depending on where the leak is coming from, this will determine what needs to be done. If it is coming from the front pinion seal, then it may be the pinion bearing. This is a common failure on this vehicle. The differential would need to be rebuilt to repair this. If it is leaking from one of the axle seals then it may just need the seals, but the bearings should be inspected at the same time. If you don’t plan on doing this yourself, consider YourMechanic, as a certified mechanic can come to your home or office to repair this.
