My 1998 528i with standard suspension has 120k miles on it. It's been getting wiggly and squishy on rough and uneven roads so I figured time for suspension work. I had an indy mechanic replace my front shocks and thrust arms a few months back but I'm going to tackle the rear myself. I've read through a lot of posts and procedures on the rear shock and ball joint R&R and feel like I can give it a go.

My real question (at this point anyway) is while I have things apart what else should I replace back there?
