Rear Diff ?
OK so I'm out laying on the ground trying to put the hitch on my truck and I noticed that the rearend where the rear bars attach to the differential, YES right where the U bolt go through. It seems that there is a gap and it look like this on both sided. Rear of the rear trailing arm between the differential axel and trailing arm in the back looks like it's loose there is about 1/4" gap it's not pulled up tight. front side of the U bolt looks pulled down tight but the back is up a bit. Obviously it's a coil spring rearend 1/2 ton. Tried to tighten with cheater bar and ratchet and U boly nuts won't move at all.
Any thoughts? Looks like might have been moving a bit as well cause where the shackel and the Ubolt on the differential meet got a shiny spot on the UBolt and I know that can't be good. TIA Soba |

Re: Rear Diff ?
You need to take it some place that can put a air gun on it and undo it. It sounds as if whoever tightened it up did one side first then tried the back side and left it thinking it was tight.
U-Bolts need to be took up together so it pulls up tight.

Re: Rear Diff ?
worst case senario, cut the ubolt out and get a new one with new nuts, might as well do both sides if you do one
