I have a 95 formula firebird lt1 i just recently purchased, I have been noticing a squeak/semi howl from the rear of the car (sounds like rear end) when i make a slow right turn, at first i thought it was a brake hanging or touching, but upon inspection it is not. I have never heard a rear end make this kind of noise. there is no grinding or actual howling noise, just kinda a squeak. any ideas on what it could be? perhaps a dry seal??? I dont wanna tear anything apart till I have an idea what im looking for. Thanks

 

Rotor is rubbing the caliper bracket when turning, this happens a lot on LT1 rear brakes.

Find the wear marks where the outer most edge of the rotor is rubbing and do some clearaning on the caliper brackets.
