were both longbeds so kinda makes it easy for me to just slide around under the truck since it sits pretty high. i would just go back and start tightening things down. u bolt, shock bolts, shackle bolts...than if it matters take the wheel off and make sure nothing is loose on the brake assembly. i would just start checking the caliper bolts and what not. i learned from clunks it could be from things you wouldn't think it should be. i will say with the traction bars i installed it feels like it just tightened everything in the back.
I will start checking everything this week. It's not my daily driver so I don't have to be super worried yet lol. My wife is having knee surgery tomorrow and she's said I worry more about my truck then her haha
