Advice on a Suspension Noise

I finished installing BC Coilovers today, and double checked everything before I got it down off the lift. When I took it for a test drive I am getting a random knocking sound from the rear. I crawled under there and everything seems tight.

It sounds like a loose bolt but nothing is loose. Nothing seems to be hitting. I'm not sure maybe the shock is extending to its limits and that is the knocking noise.

I guess I will just put it back up on the lift in the morning and give it a once over.
 
Did you check your rear sway bar? This has been a common problem with the right end link nut coming loose.
 
Yep checked both end links, they are good.

Update, I found the problem, was a loose bolt on one of the SPC camber plates. Did the MM inserts while I had it up on the lift. Wow those little things are awesome. Couldn't believe the difference those made.
