Drivers Brake Grinding Please Help
Alright so to start off i have an 09 gt all stock and has been in a bad accident with previous owner(s). For a while now i have herd a grinding noice from the rear drivers corner of my car, i checked out around the wheel and found grooves worn into my caliper anchor. Since then i have replaced just about every part that should relate to the problem (which i have searched for and no one has had). I have replaced the caliper, pads, rotor, caliper anchor, the axle shaft, axle shaft bearings and seals yet the grinding is persistent. I noticed today that my sway bar appears to be bent on the drivers side, most likely because someone had done a horrible job welding it after it has completely broken. Also, there is slightly more play on the drivers side axle shaft than the passengers vertically (pulling axle shaft up and down) but when i swapped the shafts it continued both before and after i changed both bearings, seals and the drivers axle shaft.
So now that i have replaced most of the parts that would relate to it i am stuck and dont know where to go. I went to a local autoparts store and talked to their techs and they recommended i take it to the dealer or to an alignment shop and have them check the rear end. Anyone got any other ideas or possible solutions? Im posting a pic of my worn caliper anchor if someone would like more pics so they could help ill gladly take more.
