knocking in rear
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?

Re: knocking in rear
I don't know about "common" but I've seen a couple that were loose... One was on a 20xx with 55k. So.... Maybe just random...If you had to spray a catalyst to try to turn it I'd just cut it off. Cheap part.. A lot less headache...

Re: knocking in rear
If you have a torch set, heat the nuts up and tighten...( as long as no broken parts)

Re: knocking in rear
I pulled 2 sets of trailing arms yesterday off parts frames and I'll tell you what that was a major PIA ,I had to heat the u bolt nuts and use a heavy duty electric 1/2 in impact to bust them loose ! and then had to work 30 minutes just to get the u bolts out with 48 years of road crud packed in the trailing arms ,NO FUN !

Re: knocking in rear
Same thing was happening on mine. I found that one U-bolt was slightly loose and used an impact wrench to tighten it up, all's good...
