I installed H&R sports with eibach pro dampers this weekend on my 99 sedan, now i get a knocking sound from the rear passenger side of car. Double checked that everything was torqued to speck. What could it be. My lca bushings are only a year old and look fine.

 

double check lug nuts are tighten down, check the strut bolts, make sure the spring is seated on the strut, did you take something off and not put it on. can you stand on the trunk inside and jump up and down and hear it? its putting about half an hour into looking into everything and retorq everything down, thats all i can say. hope it helps

sounds like something is loose

 

did you cut the bump stops before re-assembly? also make sure you tightened the two bolts that hold your trailing arm to the car

 

i alread re torqued all of the bolts, and the pro-dampers came with bumpstops that dont need cutting. I bought new top hats and related bushings aswell.

are the bumstops supposed to be tight on the piston? the front ones are tight but the rear ones that came with the kit slide around really easily

 

I just stood in my trunk and bounced it around but couldn't hear anything. am i the only person who's had this problem?

Are you sure your exhaust isn't bumping against something? Do you have a rear sway bar? I had this same problem and it turned out it was my exhaust hitting the sway bar. Which is why you wouldn't hear it by bouncing the car around while it's not moving.

no sway bar. but it does sound like metal on metal. I give up. I'm bringing it in to my mechanic today.

 

Let us know what it is when you find out.

well, they checked all the bushings, checked that everything was tight and it was all fine. I'm going to remove the damper on sunday and check if it is blown. It shouln't be though its brand new and the noise started as soon as i installed the dampers. I'll post my findings on sunday.
