I need some help. I recently hit the curb damaging the rear right wheel. I slid into and over the curb, hitting pretty hard. Wheel was gone, axle was replaced, brake caliper bracket replaced however my brakes still rub agains the rotor. Does my differential need to be changed?

I noticed there is a small gap between the diff and the bracket. Is there supposed to be a gap.

Any way around getting a new diff and if not, how much should it cost to replace. Thanks for the help.

 

anyone?
