Title: rear noise
Post by: 318lotis on March 07, 2010, 12:59:13 PM

strange delema, while rolling i hear a rubbing sound coming from rear, the rear wheel bearings are ok, the rubbing noise is constant while moving except when shifting into third gear the rubbing sound stops for two or three seconds.

Metallic rubbing kind? Or bushing/plastic rubbing kind?

Try pulling the parking brake (just slightly) while you're moving.  Might be the shoes are out of adjustment or one of the cables is hung up.

thanx, my mechanic claims the rotors are bad and needs to be replaced, i plan on doing this and will follow up to let everyone know that bad rotors can cause an irritating rubbing sound that can be mistaken for bad wheel bearings or bad differentail

Have him re-adjust the parking brake and lube the brakes well with high-temp grease.  That parking brake is painful to do after the wheels are mounted.

Not to be Mr. Obvious here, but I always re-torque the wheel lugs when I get the car back too, over-tightening them with an air wrench will eventually warp the rotors.
