Installed PSS9's today, now I have a weird clunk sound from rear when I hit a pretty big bump at higher speeds. I have the rears set as 3, 1 being stiffest.

On smooth roads handles great and no problems, second I go into a bigger bump in road the rear clunks usually on turns. Especially if one side is higher than the other. What can it possibly be, I had no sounds before the install.

Could it be something with sway bar?

Does the setup need to "break in" or is there something wrong with install?

I haven’t purchased the Kmac kit just yet, but do I need that to get rid of the clunk???

Any help greatly appreciated

Thanks Andrew

 

ive had this problem and it was one of the connectors that holds the sway bar on.

best thing is to look underneath and see if the sway is on properly.. this is probally the problem as it sounds similar to my noise

 

Ok how do you know if the sway is on properly or not?

 

the sway is held on at 4 points. 2 on each end and 2 on the middle.

there is a u shaped clamp that holds the bar to the car. One side was lose and made a knocking noise on mine... look under the car, at the sway bar and see where it is connected... then see if anything looks odd.
