    creaking sound in rear (not interior)

    My brother has a very clean 98 trans am with auto transmission. We installed frame connectors, boxed control arms, tubular panhard bar, sway bar bushings, springs, shocks, transmission to rearend brace, exhaust hangers, and I believe he installed a trans mount. The rear end was rebuilt, too.When the car is warmed up, we get a creaking sound from the right rear when slowing down to around 10 mph. It sort of sounds like it's in the brake, but he recently serviced them. It made the noise before the brake job. We lubed every bushing to eliminate squeaks but we still get this noise. This car is very clean and was not abused in any way. Does anyone have any ideas on what to check? I appreciate the help.

    That's alot of poly bushings and they are known to be noisy, what about the coil spring rubber mount-is it still there after the swap? exhaust hangers/mounts?

    Another thing you might try is when going slow 5-10 mph, pull up on the
    e-brake slightly while holding the release. This is how you would use it in
    a real emergency, so it's good to know how to do it anyway. May be something dragging from the e-brake.

    Thanks for the help. We thought about the urethane bushings in the new suspension parts making noise. My brother temporarily put the old pieces back in and it made the same noise. We installed new spring cushions with the new springs. We installed new exhaust hangers and lubed the inside and still had the noise. I will try the e-brake idea. The noise seems to be coming from the wheel anyway, but noises can be hard to track down to a specific area. Thanks a lot.
