So I had a new diff put in the back of my car. The diff had entirely new brakes installed onto it, so I don't think its the brakes squeeking, but its been suggested that I may need new wheel bearings. The squeel only seems to be coming from the back right wheel and it squeels pretty much every time the car moves, braking or not. However, the squeel does seem to get louder when I hit the brakes, or when I make a hard, fast turn. What do you guys think?

 

Does your e-brake work okay? Have drums? Have you checked to see if maybe one of the e-brake cables might not be rubbing? Check the e-brake adjuster link / bolt. It might be rubbing on the drive shaft.

 

The rear end I had installed upgraded me to disc brakes in the rear. The e-brake does work and the cable was replaced when I had the diff installed. I'm wondering if maybe the mechanic who did the swap did everything right...since I did get it done at Canadian Tire. :S

 

Probably a disk rubbing and or they did not use anti-squeal when the pads were installed. That's my guess as I've done this mistake myself.
