So I installed the Eibach Pro Kit springs and Eibach front upper control arms on my '09 X. After getting it back from my alignment guy I pull into my driveway and heard a loud clunk coming from the rear passenger side. I reserched and read every possible thread related to clunk causes. I ended up jacking up the rear end to find one of the sway bar end link nuts had loosened up. Torqued it up and checked the other ones and now I'm clunk free and riding cool and quiet

Moral of the story - check all nuts and bolts from time to time! our beasts will loosen them up over time.

 

Glad to see you got the issue resolved. Post up some pictures of your new drop.
