Lately, I have been getting this weird squeaking coming from the rear of the car. It only occurs when you let off the gas in a lower gear, or when you are halfway through letting out the clutch in reverse. The frequency increases as you increase speed, which makes me think it is coming from somewhere in the driveline. I just disconected my rear sway bar with new polyurethane bushings (ungreased, whoops) thinking it make have something to do with that, but it had no effect. I also sprayed some white lithium grease on the rear u-joint just incase it had something to do with it. It doesn't seem to be metal to metal squeaking, rather, rubber to metal/ rubber to rubber, but I could be wrong. Maybe it has something to do with the watts linkage/ trailing arms? None of those bushings have been replaced, but they look like they're in pretty good shape. What else could it be, brakes, shocks...? Any suggestion is appreciated.

thanks

 

Axels bent slightly causing brake pads to squeek against brake rotor.

Straighten axels at engineering shop, and use an anti squeel compound on the backs of the pads.

yeah, but I have rear drums

 

When was the last time you had the drums off and inspected them, the brake shoes and hardware, along with the e-brake adjusment and cables?

 

Well I just adjusted the rear brakes a month or two ago, come to think of it. The drums were taken off about 3,000 miles ago, and had new wheel cylinders put in.

 

did u ever sort out your squeaking ?

 

i believe it's the shoes rubbing, since it started happening after I adjusted the brakes. I haven't done anything about it yet, but I think it'll stop if I back off the adjusting nut a little bit.
