annoying squeak from underside?
 

hey all, wondering if anyone might be able to give some advise... while driving especially bumpy roads, and sometimes even when starting from a stop, i hear this *squeak squeak* noise coming from the underside of my car. as for location, just from the sound, i think its coming from the rear. i put the car on the lift at work the other week, and couldnt locate anything obvious. the bushings in the rear look a little worn, but nothing more than to be expected. i greased everything i could possibly think of, but the noise persists. i noticed that the rear upper spring perch rubber made a similar noise when the spring was moved, so i saturated it with a spray lubricant. made no difference. the car has (and most of this is hard to remember since i did the work 5 years ago, then the car sat for 3 years while i was w/o license)
- tokico illumina shocks/struts
- energy polygraphite bushings
- the blue stiffer/lowered springs (racing beat?)
- the (racing beat?) huge front and adjustable rear sway bar

with the vehicle in the air, i couldnt get enough movement from the suspension to listen for anything, nor can i get enough movement from bouncing on the corners on the ground.

one last thought: could it possibily be from the rubber exhaust hangers? when i put the rb header, presilencers, primaflow stuff on it, i replaced all the rubber insulators with new ones.

thanks for any feedback in advance!!

ps: wish i had found this forum years ago!

Aftermarket bushings tend to squeek a lot especially if they haven't been greased or they've dried out.

that was my first assumption... i thoroughly greased all the aftermarket bushings on the front of the car, as well as the factory bushings on the rear. (only aftermarket bushings on rear are for the sway bar, which i greased also)

Try shaking the car with your hands and listen for the noise.

yeah, ive tried that, but with the stiff suspension, its hard to get *any* movement... i guess i was hoping someone with a similar setup mightve had a similar problem...??

If you think it goes squeek - squeek from a stop, how about the u-joints?? does it sound like it's rotational??

i really dont want to think that, but ill check tomorrow. heck, ill check everything tomorrow again. its weird that it doesnt do it on every start from a stop, but there are certain roads here in town that it always cause that sound, even my driveway...
