Well, I was doing fine and then everything got screwed up. I am rebuilding a 1956 3600. I pressed the old kingpings out and drove the old bushings out of the spindles. I then drove the new bushings into the spindles. Heavily greased the thrust bearings and spindle bores and placed the new kingpins in the freezer for a few days to make them easier to press into the spindle bores. I went to drive them in with a drift and 3 lb sledge and after a few good whacks I could tell something was wrong. The new kingpin didn't press into the spindle bearing at all but instead destroyed the upper spindle bearing. Skewing it to one side and gauging the hell out of the bearing surface. It is now ruined. I stopped at the one side. Now I guess I have to order an entire new kingpin set just for one bearing and am stumped on how to drive in the new kingpins without destroying the bearings. Any and all suggestions welcome. How do you do this?
