Hi all,

I'll get the essential details out of the way first:

'04 Coupe
Automatic
85,000 miles
Slowly driving me insane

So I've developed the dreaded mystery rear creak / squeak.
After searching the forum for similar issues I had my local mechanic lube all of the bushings in the rear but that hasn't solved the problem, and he's at a loss as to what it could be. He says that everything's tight and there's no play anywhere there shouldn't be.

It's a creaky kind of noise (similar to rusty hinges when opening an old wooden door), happens at all speeds on slightly uneven roads though road noise drowns it out past 35mph, and sounds like it's coming from the rear RHS. As best I can tell it's coming from lower down near where the bottom of the spring sits but the sound could be traveling from elsewhere.

It can be replicated when stopped after driving by applying a little downward force to make the rear bounce, but can't be replicated after the car has been sitting for a couple of hours. Once you drive it again it'll start happening almost immediately (driving straight, cornering, all the time) and when you park up you can replicate the noise by pushing down on the rear RHS panel. Again, waiting an hour or two and the sound can't be replicated.

When going over a speedhump/speedramp with the front wheels the creak sounds louder than when the back wheels go over it, presumably from the weight being concentrated on whatever it is that's creaking.
I wouldn't mind too much but it makes the Crossfire sound like a 100 year old rustbucket (and is especially loud in indoor carparks!) and something that looks so good shouldn't be forced to suffer that kind of indignity.

If anyone can offer any insight to save my sanity I'd greatly appreciate it, and anything I can do to encourage answers (beer money in the form of a cryptocurrency such as Bitcoin or Litecoin) will gladly be provided!
