When backing up, there is a loud vibration with accompanying "vibration sound" upon braking. It only does this in reverse, mind you. It's definitely coming from the LR. It's very noticeable to all passengers, maybe even outside the car. It almost feels like the brake caliper has one bolt missing and it's slowing pivoting with the wheel. I checked this and it's not the case. There's no clear movement in the wheel with the car off the ground.

If I remember correctly, isn't there some anti-dive design specific to the w109 rear-end? There seems to be a sort of collar at the end of the axles that looks like it pivots on the axles. I can't tell very clearly, but is there a bushing in there that when bad could cause this noise?

Any advice or insight on this? I'm dedicating a full week to do a BUNCH of work to the car and would like to address as much as possible.

Thanks!

David
