I have Eibach Pro-Kits and stock shocks. How do I know when my shocks are done? I hear squeaking sounds from the back every time i go over a speed bump. Is it time for new shocks?

What happens if I keep driving on a bad shock? How much time do I have before getting new ones? Do I need to change them out immediately?

Thanks much.

 

I have Eibach prokits on my 02 tl-s. You know how prokits give u slightly bigger gap in the front compared to the rear? Would koni yellows drop the front an additional .5" to match the rear gap? And keep the rear at the same height?

 

the shocks shouldnt lower the car that is left up the springs, unless there coilovers

 

The Konis have adjustable spring perches (1" of adjustment I think). You could probably fine tune your f/r ride heights using them.

 

1. Squeeking is not from the shocks, it's the bushings. Your installer should have put some polyurethane tape there. oh well, just an annoyance, I wouldn't worry.

2. Worn shocks will feel bouncy. ie. when you go over bumps your cheeks will jiggle a bit longer than normal.

 

check the struct mount too, if your car make this noise at low speed, this could be it.

 

well, I've had the prokits on for about 50,000 miles now with no problems before.
