Upper King Pin repair

[CT-BLAZER]

Hard time seeing thread structure.... Looks like you moved the threads...

???? Do they make replacement parts oversized?

Possibly drill it out oversized on a mill,. Tap it. .
Make a new threaded insert out of tool steel + heat treat it.... Install the insert with hi strength loc tite.

Thinking of making the insert like the insert on a Dana 44.... Just none adjustable.

Questionable practice, but I could make that pin ( oversized,) out of tool steel, heat treat it....

I can mig it, I might see if my buddy will tig it for me.

Don't overthink it, MIG is totally fine.

If it still threads in at all it should be easy, only weld the bottom.

I have some stock inner " C's " if you need 1 . Clean threads .

I think I'd try a new king pin first. Maybe the kingpin threads are most of the problem vs the inner C?

I got a new king pin and a tap. I ran the tap half way down and stopped, then put the new king pin in. I started torquing it at 25ftlbs. and went up by 25 at a time till I got to 200. I didn’t feel like pushing it past 200. I then welded the bottom and called it good. I think with 200ftlbs holding it and being welded it should be good to go.
