The clunk on my car is really bugging me and I'm trying to figure this out. It gets better the longer I drive and it's worse when it's cold. Also, it's only happens on a sharp drop like say a pot hole style drop or a quick upward force of the suspension. I can hit dips on the freeway with out a single bit of noise.

Anyway, has anyone found a solution to this? I was doing a little reading and just looked up rear suspension clunk and found out the the STI's are notorious for having this rear suspension clunk. I wish I knew more about our suspension, but I imagine it's pretty similar.

Here is what I found:

"As many of you are aware inverted struts can develop an annoying "clunk". The problem is apparently caused by a lack of grease being distributed from the strut chamber onto the damper body. This causes two coated (Teflon?) bushings to not receive proper lubrication resulting in wear and rear strut movement becoming noisy, clunky and rough. One symptom is that when the car is stopped and the rear end raises up a bit, it remains up until the car begins forward motion then the rear suspension allows the body to drop abruptly with an audible clunk.....most of us find this really annoying.

The cure is to somehow cause the inner sealed bushings to become greased. There are only two ways I know to do this.....1. Remove the entire strut assembly, disassemble, clean and repack with grease and reinstall, or, 2. Remove the rear struts, disassemble, drill and tap to install a grease fitting, clean, repack and reinstall. #2 is intended to keep you from having to repeat #1 and save your struts in the process by allowing you to either routinely add a dab of grease or add grease when and if the clunking returns."

I'm almost at 3000 miles and at that point I wanna have toyota check this. Any thoughts? Could we possibly be experiencing a similar issue?
