I recently installed a 2"BB on my 2003 WJ. All of the sudden, the rear suspension sounds noisy. It almost sounds like a metal to metal thud as I go over bumps. I lifed it up and looked for an abnormal stuff, but of course I could not find anything...

At first I thought it was the shocks, but they are tight...

Thanks.

I dont have a WJ but my ZJ does the same thing. What i think it is, Is the blocks shifting a little while the suspension is flexing.

WJ's use a unique upper control arm on their rear suspension. It's like an "A" shape, with the apex as the attaching point to the rear end housing with a type of ball-joint.
Yours might be hitting/binding at the ball-joint point. Look for clearance, and if there's any shiny spots where it's been hitting/rubbing. JMO

So how would I fix the problem then? lol

If that's where the problem is, there's a spacer for it so it'll more line up with your recent lift.
