Ever figure out your issue? I too get a slight knock(feel) from driver side. I can manually turn my wheel left to right (the amount you get with truck off and ignition off) and hear/feel knocking noise. I can put my hand over the upper control arm and turn the wheel left to right and feel the knocking on control arm. I re torqued everything upper cross bolt and spherical bolt(total chaos uppers) and still get noise. Alignment shop did a "diagnostic" although I didn't ask for one and said it was my wheel bearing (they wanted $860 to replace a long with alignment), after alignment I went picked up a new wheel bearing and replaced it even though the stock one looked and seemed fine and still getting that slightly knock. I too recently installed king coilovers and upper Total chaos arms about a month ago. I'm stumped 🤔
