Grinding/squeaking noise from rear when turning About 4 months ago, my '99 trans am was hit in the right rear wheel @ 45mph. I got the car out of the shop last week. The entire rear axle assembly was replaced with a used one from a '99 SS camaro, I'm unsure of how many miles was on it.
For the last few days I've noticed a grinding/squeaking noise coming from the right rear when I'm turning at low speeds, 1-10mph.
I took the wheels off yesterday and noticed the caliper bracket on the passenger side was ground up on either side of the caliper piston. The rotor partially ground up as well. I moved the passenger side rotor to the drivers side to see if the noise would follow the rotor and it didnt, the noise stayed with the passenger side and rotor I just put on the passenger side showed signs of rubbing the caliper bracket.
When I put the caliper bracket on, there looks to be a good 1/8-1/4" gap between the bracket and the rotor on both sides and there doesnt appear to be that much back and forth movement on the axle.
Does anyone have any idea whats causing this? I'm hoping someone here has had a similiar experience. I did a search and it didnt turn up much information.
You can see where the rotor was grinding at the top left.

Here's the caliper bracket, you can see where the rotor was rubbing the bracket to the left of the piston.
