Kingpin bushing pressing
Where do I take my new kingpin set to have the metal bushings pressed in and fit to the kingpins? A suspension shop or like an engine block shop? Also, I have 4 thin shims? Where do you place these when reassembling?

Either place should work.
My last bushings I did at my cousins auto shop with his manual press. If you look around a garage may have a press and either let you use it or do it for you.
I am clueless on the shims. Sorry.

A motor machine shop would have the problem machine to fit your pins to the new sleeves.
As for shims.....don't really remember where I put them the last time I did pins. I think they would go on bottom side(with bearing) to take slack out of up/down movement. Not sure if there is a specification for it or not. Never saw any.

just went through this -- i think that the 'shims' are a seal that is to go between the top bushing and the middle section to keep the top grease out of the middle section. the guy at the machine shop that did mine recommended leaving them out all together- said he always does them this way. i took his word for it, but i would be interested to know if i am wrong.

Gents, the shim goes on top of the bearing in between the spindle and the I-beam. The shim or shims only need to be inserted if there is a gap between the components of .005" or greater. Insert shims until any gaps are less than .005"

King pin bushings and shims
I sure hope you used bronze bushings, nylon sucks. Machine a stepped driver to remove and install the bushings with a hammer. You need to ream the bushings with a "King Pin Reamer" not a Sunnen hone machine at your local machine shop. Those idiots will bell mouth the bushings, check for fit with grit and scratch the hell out of your pins. End result, loose fit worse than the worn bushing. The reamer has 5 cutters, a long pilot shaft and a tapered sleeve that aligns the reamer. The shims are placed above the beam to remove end play, you want the minimum amount of end play. Lube at every oil change ( 2,500 miles) and they will last over 400,000 miles. Been doing it for over 869,000 miles on the twin-I beam axle.
