Clunk occurs in the steering when turning mostly, but sometimes when spring compresses during normal driving. It feels like it is coming from the drivers side, like the track bar ball joint/mount. I am running a rusty's track bar (not hd) on 3.5" lift w/ 31's. Only occurs when wet, ie during rain or after a rinse of undercarriage. I've dealt with my clunks before, but this only when wet is weird.
