Re: hopefully someone out there has an answer for me !!!!!!
King pin front ends are the simplist in the world. Go to a local library and look at a Motors Manuel on 49 to 55 chevy trucks. They pretty much stayed the same up to present 18 roller trucks. In fact they are easier to work on than it is to explain how to work on them. Bear skins and stone knives technology . Caster angle is set with shims between leaf springs and the I-beam, camber dosent have to be messed with unless the truck has been in some sort of a front end wreck, like a real hard ditch'n. I have always taken the entire axel out of the truck to press out the king pins. After the I-beam has been striped of everything but the axels and king pins. I have done this and and watched this done with hammers rose bud torchs drift pins and mucho cursing with a touch knuckel flesh. But I've always figured four u-bolts taken out with a deep socket on a good impact and the I-beam is in the 50 ton press in 45 mins. The hardest part for me was getting the rite size ream and reaming the i-beam bushing for clearance on the k-pins. I perfer taking the I- beam out over leaving it in the truck because of the lack of room to swing a hammer under a fender, that and I've got a 50 ton press. A good machine shop can rebush the axels and ream them to fit your king pins. Iv'e always done this myself, being born a poor child. Russell
