Clunk in the Trunk

[FunfDreisig]

2009 E70 X5 35d 80k miles — A week ago I hit a sharp pavement transition in a road construction area (across the road). Since then we have had a clunk in the trunk..err cargo bay. It is pretty loud. Sounds like someone is hitting the body with a rubber hammer once or twice each time we run over even slightly rough pavement with the right rear wheel. After removing EVERYTHING (including the spare tire) from the rear, the clunk is even louder.

I’ve done a physical/photo inspection with the X5 on jack stands and see no obvious broken or loose parts. The exhaust hangers are in good shape. I dropped the plastic panels that cover the fuel tanks and the tank straps are tight. The suspension bushings “look” good. But I know “looks” can be deceiving, especially with BMW bushings that can be fluid filled.

But I’d like to eliminate the easy stuff first. So I’m thinking I’ll start by replacing the rear shocks, including the:
1- upper guide support - 33 52 6 776 557
2- lower guide support - 33 52 6 776 399
3 - bump stop - 33 53 6 6 773 236
4 - bump stop sleeve - 33 52 6 776 132 ?????

But before I place the order, do you have any tips/tricks/recommendations?
