This could be the spring coming unseated from the strut. I would take it back to the place that did the work.

Chances are you’re right about the top strut nut being loose. After installing KYB-AGX's my right front loosened up after a few days of hard driving. It drove me nuts until I figured out the cause of the noise. A couple of good yanks with a wrench solved it.

Yeah, that's about right.


Did you use new locknuts for the top nut and the 3 small nuts that secure the strut to the body, following the manufacturer's service procedure?

Didn't think so. Tighten that top nut to something like 43 ft*lb (making sure the strut shaft doesn't turn by holding it with a hex key).

Was it more like a really load creak? I had this problem for about two weeks when ever I came into my driveway or on slow turns and slow speed bumps. It went away for the most part. You got me thinking that I should look into it a bit more.

The clunk is most likely a strut top nut.

The creak is most likely the plate atop the spring that wasn't aligned properly when installed.

I have had this problem since I did my suspension install. It was fine at first, then it began to rattle. I later found out it was the strut mount bolt, and tightening it resolved the problem. The rattle is back, not not like the strut rattling around. It now seems like the strut mount cap is rattling against the strut mount on the frame (read: the strut mount cap is flexing into the frame). I plan on replacing the strut mount caps with Grp N caps, in hopes that it resolves the flex. My kybs are rather stiff at 2f/7r with tein s-tech springs.
