Been chasing down this knock in the rear drivers side.Just bought the truck.Sounds like a bad shock bushing.Finally laid down on my back and pushed with my feet and arms on the bed to make the truck bounce.Holy crap!The U bolt on the rear axle was rocking back and forth.Nothing is broken.But could this bolt just loosen like that?I sprayed it with some monkey piss and tried to tighten it,Nothing.That B@#%h is tight.So I'll let it sit over night and work on it when the sun is up.Probably just cut it off and put on a new one.Is this common?
