Clunk in rear passenger area

[shaman1204]

when driving over rough surfaces going 15mph+. It sounds like its coming from the wheel area. To describe the sound, it sounds like the trunk is bouncing up and coming down when I drive over a bump (it is shut.) Does anyone know what this would be from? I have had the car just over a week and I think it has been there the whole time, but I really noticed it this Sunday for the first topless experience on Lake Shore Drive. I am taking it in tomorrow for an alignment at an indy I was wondering what to look for. BTW, I did get the PPI at another indy shop and it checked out fine. I trusted them because the closest P dealer was 50 miles and they worked on customers' Boxsters regularly. There was one there waiting to be picked up. Could they have missed something?

Me too, so far I've been told to check the sway bar mounts (they were fine) and the track control arms (they look OK), still looking....

Paul, what about motor mounts?

When I replaced the drive belt, I revved the motor several times with the cover off and the motor did not move enough to make me believe the mounts are bad.

Plus the noise is usually noticed at very low throttle positions. It really sounds like the trunk is open except it seems to be lower. I've checked the muffler (the dealer replaced it right before this started), but it seems to be firmly attached.

Also right after the dealer replaced the muffler, I was in a hurry and turning left near WOT from a traffic signal, I heard something pop like a bolt broke, but I can't find anything.

Maybe they left a tool of some type in there somewhere.

I hate warranty work since I can't do it myself!!!
