I brought my 1994 z28 Camaro in for a diagnoses to make sure it's in tip top shape. Nothing is wrong with it (YAY) but the mechanic did point out that there's a sqeaking noise in the right rear end. I've noticed it. It's really impossible to tell where it comes from (I think) but ya he said the rear end. It's soooo annoying lol. What could it be?

(It's a very quite and high pitch sqeaking sound). When I'm on flat roads it doesn't do it.

 

by my count the op has 7 camaros. 69, 84, 85,94 base, 94 z28, 95 and a 97. me thinks this is a spammer.

 

had a add in his/her sig. once i gave infraction the sig goes away until the infraction times out. 5 days. if sig stays he/she goes.

 

Could be some poly bushings (have any?) that need greasing...

Ya sure the sound is outside the car or inside? I had a REALLY annoying high pitched squeak inside that turned out to be where the rear seat clasps on both sides that metal was vibrating -- added a little lube there and it's gone. YEA!
