gto-dave,
can you give more info about this, "the sound was coming from upper mount bearing plate". A picture would be great but a better description of where this is would be even better. Thanks.
[Edit]
Checked the upper brace mounts and they are tight. The weak knock sound seems to be coming from the passenger door when it flexes. Will grease it and see what else I can do. Luckly, all else seems great.
[Edit Edit]
It was from the front springs moving around. Had the dealer install a layer of 3/32" of rubber under the Eibach springs and the sound is gone.

Just an update. The sound was getting worse, so I lifted it and it turns out it was coming from Right side front only. There is no angle adjustment on the FX for the lower mount, & upper perch was parallel to mount, so nothing could be done there. The Spring was sitting perfect and was not moving at all, as well it shouldnt due to the fact that it already has pre-load. Before I lifted, I was thinking it may have been caused by spring possibly pigtailing & hitting perch on the little step where it seats. After inspecting it, it turned out that the sound was coming from upper mount bearing plate. Like a big click at acertain point while turning wheels. This is the best part . . . I removed the strut bolt and tightened it down again. That was it, sound gone . . . ??? . . . Maybe it's in a different position & the car likes that. Easiest fix ever! kind of reminds me . . first thing to check if somethings not working . . Is it plugged in? :lol:
Wanted to throw this out there as a remedy if anyone has this problem. worked for me.
