I'm getting ready to replace my shocks/struts on all four corners of my 2006 T5 V50, along with new LCA's on the front. However I'm now hearing a rattle coming from the rear driver-side that sounds very similar to how an aluminum extension ladder would sound in the back of a truck cab. Wondering what the usual suspects could be. I'd like to get all of the suspension issues ironed out at once if I can. This thing is bouncing all over the place right now.

 

Possibly rear shock mounts:
Volvo Rear Upper Shock Mount P1 S40 V50 C30 FWD 115391 30714349, 30647413, 30678433 30714349
I'd check all the rear suspension and anti-roll bar bushings, too.
