Same problem in my 2006 z4 roadster. It cost a total of 918!to have it fixed at Pep Boys. It sucks when the ball joints go bad the entire assembly has to be replaced.

cracking noise when in reverse with steering wheel to the right (such as backing out of driveway) or when approaching a speed bump with left wheel first. Mechanics said the ball joint/suspension sockets, control arm are all bad and costs over $1,000. I hit a pot hole at about 35-34 mhp before i started hearing this sound.

Clunk noise when in reverse Had mechanic checked and found that lowered arm bushing is wornout. Replaced the pair
Bought the car used when it had 27,000 miles on it. It currently has 44,000. The car feels like at certain times the car frame is going to break in half. I have not had it fixed at this time.
