Hi All,
I have all the regular poly bushed mods on my '99 Z28 w 40k miles, Eibach pros, bilstiens, hotchkiss LCAa, BMR PHB.
The rear susp makes a squeak every time I go over a bump.
It doesn't do it when parked and I push on the bumpers.

I greased all the zerks and no difference.
The dealer said it could be the spring perches but couldn't find anything.

Anyone heard of this?
Just buy new perches from GM or what did you do to fix it, wipe em down w bearing grease?

Thanks
Evan

 

I have the same issue right now!
Just that I dont have any of the suspension mods and my car only has 29K miles.

 

I also have been experiencing an annoying squeek when I hit light bumps in the road, not all the time though. If I get out right away and push up and down on the car, it goes away, temporarily. ? I have about 38k miles on my car. What the heck could it be????

 

Does anyone have a clue? Much Thanks-

 

I have the same problem fellas. I've greased and re greased everything and to no avail its still there. I've learned to live with it though.

Good Luck Mike

 

Rear sway bar bushings are notorious for drying out and squeeking.

 

Similar problem here - seems to be in the rear sail panel but it could be a suspension component. I'll check the rear sway bar when it gets back above 0 again.
