The front end has always made these strange "clunk" noises... only when you hit little tiny bumps or different road surfaces. Always scares me thinking its tie rods or A arms but they're new and good.... anyone else getting this? Steering rack bushings maybe? Anything notorious im unaware of?

 

Is it modified at all? Front sway? Shocks/springs?

 

Rule out simple stuff like swaybar end links.

 

okay, yeah it does have springs and shocks on it... i noticed the same sounds with my other s2000 as well, never really tracked it down with that one either. ill check the sway bars

After ruling and replacing what I have already, I suspect I may have blown front passenger side damper, and blown rear driver side damper.

The car drives fine other than the annoying clunks and visible streak-like stains on the mentioned wheels.

 

My 06 did the same thing when I bought it,every time I hit a tar strip it went clunk, found the upper nut on the front drivers side sway bar drop link was loose took me two minutes to tighten and no $$$. now is quiet...Pete

 

At what speeds does this happen?

 

For me, it's most evident 30mph and below.

EVEN more so when I'm at "looking for parking" crawl speed.

 

Found it! Rear A-arm bolt wasnt hand tite, but loose enough that when i hit the wheel with my hand it would replicate the noise. Tightened... back to normal! Let's hope my alignment is still on point lol
