I need some sage advice about rebuilding the king pins on my 48 New Yorker. I'm having trouble getting the welch plugs to stay in place. I've read that they fall out quite often leaving the bearings/kingpins exposed to dirt as well as letting grease drip out before it gets to the bearings.
I've cleaned up the seating surfaces because they were a bit nicked up. I installed the welch plugs (which are very tight fitting) and got them to seat properly, then flattened their domes, but when I pump in grease the plugs lift out.
Got any suggestions?
If all else fails I was thinking of attaching them with a couple of tack welds or using some JB Weld. I don't anticipate having to rebuild the king pins again because of the low mileage I plan to put on the car.
Thanks.
