This is for my brother he has a 1989 G 535i Sport Auto.
It started getting a knocking noise coming from the back passenger wheel only when he accelerated???
We jacked back up but couldn't hear or see any reason for the noise. All the wheel nuts where fine and drive shaft seems ok.
Then when we took the car back off the jack the noise has seem to gone.
Was just wondering if anyone has had this problem or if they new what it couls be.
