I have a 2000 Passat front wheel drive with a creaking sound coming from the right rear wheel area. I can make the sound by gently pushing the right rear of the car up and down. The sound is exactly the same sound that a front control arm made before I had it replaced. The car did NOT make this sound until I took it to a mechanic to have the front upper control arms replaced. The mechanic said that maybe putting the car up on the hoist caused the ball joint in the rear to drop and that caused the creaking. This car does not have all the control arms on the rear like it has on the front so what could cause this, the shock absorber? Or, is there a control arm in the back?
