UPDATE:
Almost done with the axle pivot/radius arm bushing install.
Radius arm bushings were a piece of cake, removed the bolt from the bushing and dropped the arm just below the bracket. Used the OTC press to push out the inner metal sleeve, at which point the screw from the press shreds up the old bushing nicely. Set fire to the old bushing, wait a few seconds and it is supple enough to push out, with a little resistance from it being stuck to the inside of the outer shell. Lube up the new poly bushings and they can be pushed in by hand, the inner sleeve needs a press or c-clamp. Jack the radius arm back up into the bracket, push/pull on the front wheel to line up horizontally and bolt back up.
Left axle pivot bushing, right side of truck, was okay too. I ordered the bracket ahead of time as the stock one was severely corroded. Dropped the axle far enough to get to the bushing, same procedure as before to get the bushing out. The stock axle pivot bushings have a metal reinforcement ring embedded into the rubber structure itself, hooking this out with a screwdriver made it a lot easier to push the bushing out when it was warm from the fire.
Right axle pivot, left side of truck, much harder. The bushing bolt would not come out. I took the head of the bolt off with an angle grinder, and used the nut to try and pull it out.... no dice. Tried to grind the bolt back inside the holes off the bracket so it would drop out, but in the end, it proved impossible without ruining the holes. Made the call to replace the bracket, and cut it off the truck with the grinder. When I pressed the sleeve and bolt out of the bushing, you could see how the bolt had corroded and expanded the metal sleeve along its seam. No wonder it didn't want to come out. Bracket is on order, just needs to be bolted up when it arrives and I'll get this POS rolling again. ;-)
This job has not been cheap....... better keep it for a while.
