I wasn't sure where to post this since I have no idea what the problem is. Going over bumps in the road, I would hear a nasty creaking noise coming from the passenger side rear. It sounded like it was in the right rear wheel well. Then my dad tells me yesterday he backed my car out of the driveway and it made that noise just giving it a little gas in reverse. Visually I see nothing wrong underneath the car. I'm wondering if it's the rear end that's going. But if it was, would it be driveable? Could it be suspension or exhaust related? Anyone had any problems like this before? Any kind of help would be appreciated.

 

List of current suspension mods would help but it sounds like either the Subframe connector or lower control arms. Check that all is tight and while you're under there, lube the bushings.

 

Mine does this too so if you figure it out post it on here. It doesn't bother me enough to go all out to fix it, but if you figure out what it is I might fix it.

 

The only things I can think of in that area of the car are the LCAs or panhard rod. Visually they look fine. I checked all the welds on the SFCs, they all look fine. By the sound it's making, it sounds like it could be a REAL serious problem.
