Update: swapped out base suspension shocks with LSS shocks that I picked up from a fellow LT-er, put in upgraded bolts on the upper shock mounting bracket and de-shimmed the front. As far as I can tell the clunking sound is gone. Not sure if it was the shocks or loose upper brackets. No longer have to crank up the radio to keep my sanity.
