Hey guys, if you could help me out at all it'd be greatly appreciated. I'm hearing a knocking noise from the rear, but the problem is i can't recreate the noise at will, and I've checked the torque on everything in the rear. I've also had the axle nuts replaced a few years ago so it's not that. Anyone have an idea of what's going on?

 

check the axle nuts if the paint on them lines up then they are not torqued down to 220lbs which should be the right torque. also check your sway bar. And lastly check your bolts on the upper suspension arm, mine got loose, and like u said the sound comes up but not at will. good luck
