55 Fargo Posted July 13, 2014 Report Posted July 13, 2014 Hey all, have to change the u-joints, at least the rear on the diff, as it has play. The diff is a Mopar 8 1/4 diff bolts are 1/4 inch fine thread, with 3/8 bolt head. 3 of the 4 unbolted just fine, #4 would not come off , not with heat nor with PB Blaster, now the head is rounded off. I am now going to a Buddy's shop, to use the oxyacetylene torch, what a PITA. This old truck has had it's share of rusted in nuts and bolts... Quote
MBF Posted July 14, 2014 Report Posted July 14, 2014 I'd try welding a nut to the rounded off bolt head, and give that a good shot of your favorite penetrant and then rattle on it with an impact gun to see if that will back it out. 1 Quote
nonstop Posted July 15, 2014 Report Posted July 15, 2014 What about vise grips clamped tight? 1 Quote
55 Fargo Posted July 15, 2014 Author Report Posted July 15, 2014 Gonna heat it red hot , then try vise grips, if that fails, weld on a nut, then try, shouldn't be too big a deal. Today bought new ujoints and strap/bolt kit, so ready to go... Quote
