I have a front end thunk which I have not been able to diagnose. My suspension setup is as follows:
Steeda Sport Springs
Tokico DSpecs
Steeda Adj. Panhard Bar & Brace
Steeda Upper Strut Mounts

Please note. I have upgraded my strut mounts, so the strut mount TSB is not my answer. I have had the suspension installed for over a month, and over the last few days I have been getting an annoying thunk over any bump that I drive over (no matter how big or small), only on the front drivers side. I jacked the car up last night and tried to tighten the nuts where the sway bar connect to the struts, but they seemed tight (by hand).

If someone has fixed this problem before, please provide an explanation, and pictures of what you tightened if you have!!!!

I am ready to set the car on fire.

 

im not totaly sure but i think it should help

 

Anyone else know if this would help?

 

I was a member of the thunk thread. After i got the new upper strut mount assemblies and the thunk was gone I got the Che K brace. I remember reading that it relieves stress and tension from the upper strut mount assemblies. Some folks said it cured their thunk.

I don't know what a panhard bar and brace are, so, you may have something better than the che brace anyway. Good luck.
