    Need help, rear end feels loose, no jokes please

    Have an 02 cab (9/01 build) with 51,000 miles. With in the last 3,000 miles the rear feels to shift around when going from power on to power off around sweeping curves. Dealer checked it out and found nothing and an independed service man found nothing that was way out of line. Do some of the rear bushings go bad but not just visually torn that any one culd see that would cause this. Need help

    That could defenitely be caused by your rear trailing arm bushings...especially if they are originals. Also, you may just want to make sure you don't have any toe-out in the rear...but I'm betting trailing arm bushings.

    most likely the RTAB. You would not know they are

    busted until they are removed. A slight toe in is harder to achieve with a busted bushing. I know because that was the way I proved it to BMW to have them removed. Once they took it apart they saw the issue. The best way I know to describe the feeling was the car felt out of control in 3rd at full throttle especially as the speed got higher.

    did they check rear toe alingment. or could

    be trail arm busing as said - or try a couple extra psi in the rear.

    My 03 with 27K feels the same way. Loose on hard

    throttle and during WFO shifts. How common is this? Car is bone stock with one track day w/Michelin PCS. What is the procudure to get the dealer to make the repair? Unless you are familar with these cars, you won't notice the problem. A casual test drive won't convice anyone there is a problem. Advice please.

    Do you think it might be your driving style?

    You mention "power off" in turns. That's an automatic oversteer producer.

    Could be broken rear sub frame mounts

    hear a an occasional rattle over uneven surfaces ...rear end feel a little disconnected ...requires welding to repair!

    I'll second that. This definately could be the

    issue.

    Hopefully it's just worn bushings or something.

    Do you hear any creaking noises coming from the rear on uneven pavement ?

    Loose rearend feel. Under hard acceleration.

    My e46 m3 had the same issues. I had my rear trailing arm bushings (RTAB) replaced. Along with an alignment. Problem solved!!! It was like day n night. No more kick outs in sweeping turns and accelerations.
