clunking in rear

[derek_m]

reg cab short box 2wd, factory duals. 3/5 drop. 1" bumpstops.

took the bracket off the control arm for the ebrake, took airlift kit out to rule out possible causes.

any idea what hits on these trucks that is causing the clunking??

someone mentioned that their upper shock bolt was getting loose. you might want to check that

After mine was put in I went back under it and found that my driver side upper shock bolt was just a little loose but the way I found it was I didn't jack it up off the ground and I had someone push the back of the truck down to make the thumping sound and I found it the problem once I tightened it no more noise

Upper control arm hitting the frame. Need atleast 1.75" tall bumpstops to prevent it.
