I'm at a dilemma. I have a 2007 chevrolet silverado 1500 rcsb 2wd with the 4.3l v6. The truck came with a 6 inch lift and tires on it so I took it off and I have replaced all the shocks, upper and lower control arms with bushings and ball joints, both hub assemblies, new upper control arm mounting bolts with new cam plates, tie rod ends, rack and pinion, sway bar endlinks, front and rear brakes, rear axle ubolts, and new tires. Everything is torqued to gm's specs. My truck continues to lean badly on the drivers side. The truck stays riding on the lower control arm bump stops on the driver's side and it is incredibly rough. I have had multiple complete alignments including caster and camber. I have had my tires standard and road force balanced. I have retorqued all the bolts and it seems to fix the problem for a while then it comes right back a week or two later. I have locktited everything, also have locktite and knylocks on driver and passenger side upper control arm bolts. I don't understand why it still continues to happen. All parts have around 2000 miles on them now. I have retorqued everything 5 or 6 times and the issue continues to come back. Can someone help me please?
