I also have the bouncy rear end. I replaced the front shocks with bilstein comforts. That didn't seem to help. I bought rear accumulators and replaced the as well. My car still bounces. I made the mistake of raising the rear end slightly by changing the leveling valve on the rear sway bar. I think this may cause my bouncing problem.

How does one measure the correct ride height at the rear?

Also my rear end sags still after the car has been setting for a day. I'm thinking that the rear leveling valve needs rebuilt.

Shawnster, I read your posts on your leaking from the front windshield area.
I just posted on a problem like that. See the post ( Leaking may not be due to windshield gasket)
