Well, while rebuilding my 60 I decided against my better judgement to go ahead and replace the king pins. Ordered my rebuild kits from WFO, Super fast service. The hardest part about this job was finding the 7/8" allen key, or hex stock. After searching countless places no one had it instock, so I was on my way to lunch and decided to stop in the local Northern Tool. Of course they don't carry anything special in that department, but something caught my eye. On the shelf sat a big arse cold chisel, so I picked it up and went over the tool isle and low and behold it was 7/8". I bought it (9.95) and took it back to the shop. I had to grind just a touch off of it because of the coating that was on it, slipped enough to fill up the king pin and then cut off enough to fill up a deep well impact socket. Works like a charm, just thought I'd share a tip with you guys and gals. Jeremy.
