Tonight I looked at the rear end of the ZHP to see what was causing the noise. After looking at the subframe bushings (which are fine), I decided to remove right rear shock because I thought it was blown.

While I have a new shock from Bilstein, I need to get the other items as the shaft is stripped. Great. Fun.
