Hey everyone,
I have been looking for good information on this all over and have come up with nothing really directed towards this solution. Short but detailed version is I've replaced my rear drums and shoes recently. I noticed that when I removed the old drum from the drivers side rear wheel that the drum almost looked crooked in the backing plate. The back half of the drum was almost in contact with the backing plate, while the front half looked correctly spaced. I figured this was why I was hearing a grinding noise from time to time from my brakes. Thought it was the drum but it was not. I replaced with a brand new drum and now the rub is even worse. Drove around the block and my drum was screaming and you can see where it was rubbing just from that 1 minute drive. Only thing I can think might be the issue is that the upper control arm on my driver's side is an adjustable camber control arm while the passenger side upper control is a fixed bar. The drivers side rear tire does also look like the top of the tire is pushing out from the center of the vehicle while the passenger side looks neutral. Would correcting the camber of my drivers side rear wheel also help realign the backing plate with the drum? Or is that being too hopeful and I possibly have a bent hub or bent backing plate?
thanks for any and all information guys!

 

Sounds like the car was in an accident on that corner. Probably bent the backing plate. Could also be a bent spindle if the hit was hard enough. Probably should have a professional put eyes on it.

Adjusting the camber will have no effect on the backing plate to drum clearance. The adjustable camber arm is probably to get the rear bad in alignment after being hit and poorly repaired.
