02 GT rear suspension chirp

[trinity_gt]

WTF causes this? I took the car out of hibernation yesterday for a mid-winter gas-guzzling spin and was reminded of something that had slipped my mind since fall: a rear suspension chirp that happens over just about all "sharp" edges bumps like manhole covers and moderate to large pavement cracks. Smooth undulations don't seem to cause it.

Quad shocks?
LCA front bushings?
Parking brake cable where it slides through the bracket?

The car has new coils and shocks (Bullitt kit) and new FRPP UCAs. As I recall, it did this before all that stuff too.

BUMP. I'm interested too, my GT seems to do the same thing

I'd have to say it's the bend in the cat-back scraping against the UCA's

The front bushings on my Mega Bite LCA's were making that same noice...greased em up and the noise went away...easy to get to so give it a try.

Hmm. Interesting idea. I'll have to get under it and look for evidence of contact there.

When I swapped out my solid axle the front UCA bushings were shot, and the front lowers weren't much better. Not to mention the quad shocks being shot after about 5000 miles...

Get the car up on some jack stands and jack up the axle a bit to see if it makes the sound while articulating the rear end by hand!

Hmm, what kind of grease do i need to get and is it available at a place like O'Reilly's and Autozone?
