Hey first gen guys I found a great writeup on the kingpin rebuild.

Dont know if there is already a link to this somewhere but if not here we go.

 

I am doing mine right now, along with a complete axle rebuild. They were slightly worn.

 

I did mine, it's in the sticky:

Any and all additional info on doing this job is appreciated. I'll be doing mine as well soon too.

What kits did you go with?

 

I'm thinking of going with 4wdfactory.com they have a all spicer kit for top and bottom with a timkin bearing for 95 with shipping.

 

Something to keep in mind when doing kingpins (i have done two d60 trucks now and lots of heavier trucks way back in the day), heat. When i tried removing them i could bend allen wrenches, break sockets etc. Some heat makes things go much easier. Don't be scared to heat cycle it aswell. Add heat spray with wd40, let cool spray more, add heat etc.

Also the torque spec is 5-600ftlbs, i usually don't go that tight (they cant really fall out). I go as tight as i can pull with a socket and 3/4" breaker bar and small snipe (my arm is a calibrated torque wrench after years of torqueing ;P). You can let it sit and re-tighten after a while too just to be sure it is good and tight. I add anti-seize to the threads for future removal.

Use lots of grease when assembling the bushings/bearings and grease liberally when in use.

Partsmike has always been really great to deal with and good pricing.

Just a comment, I got my king pin kit from Quad4x4, its very complete, I also added their 7/8" hex socket as seen in the picture this with a 3/4" breaker bar and some pipe made short work of the king pin removal. Got my crossover steer arm and drop steer arm from Offroad design.

 

I have seen someone actually bend the axle "C" by using too much heat and an 8ft long pipe on the allen wrench.

Another way to do it without heat (which I think works even better than heat) is to use a grinding disk and cut a small groove around the outside of the king pin and it pulls right out since you have reduced the surface tension of the king pin:

 

Some more advice, use marine grease when packing the nylon and king pin back together. Same goes for the bearings and other moving parts. I've been using lucas marine grease and it's good stuff. Doesn't fall apart when I get I let my truck play in the grass. When the grass doesn't want to play any more I flip her over and play in the mud.

 

That cutting the king pin near the base is some good advice!

Same basic thing I do when removing bearing from a pressed axle or something. Cut almost the whole way through, then tap with a chisel and they pop out.

 

Thats takes ALOT of heat, in that case the person obviously shouldn't be using a torch for anything. What i meant was putting heat on the kingpin itself, the C can take some heat but you don't want to heat it red hot.

You can't fix stupid no matter how many tools you put in their hands.
