I just lowered my 99gt tonight. I got the MM caster camber plates, eibach sportlines and tokico hp struts and shocks. Anyway took the car to the professionals had them do the work. The rear of the car is very noisey, like somethings loose. They checked it out could not find anything. Is this normal. What should I expect from an upgraded suspension? Need lots of info before I go crazy...

 

I lowered my car and have a noise in the rear also. I checked everything and connot find anything loose.

 

is the noise on accel/decel or when you turn or both? Is it a clunk or a rattle type sound? I'll need that to figure it out.

 

Is it a squeky or somethin like that? Did you use spring isolators? If it is squeky then and if you didnt use isolators then that can casue some noise.

 

Its not squeaky, its more like a clunk and you only hear it when you drive slow. It sounds like the rearend is loose but it isn't. When the rearend bounce thats when I hear the noise.

 

Hmm...not sure what it could be. I had my rear lower control arms upgraded and it had lower the rear of my car a lil more causing my rear sway bar to hit my tail pipe on my drivers side. I know that sounds weird but it true. Try backing your car up on some ramps and looking underneath to see if there is anything that could be causing the clunking noise.

 

I did what you said and got under the car and found that my quad shocks were loose, meaning the idiot that tighten the rear shocks forgtot to tighten the quads and oh was I pissed. Took the car to the shop called for the manager, showed him my billed, told him about the idiot that he was working in the shop, then I told him I should have cancelled payment on that check they got and reported them to the Better Business Beurea. They fixed the problem and was glad I left.
