King Pin ?
I ended up using two shims on the drivers side and I had no up and down play in the spindle, but on the passenger side I ended up with 4 shims to remove all the up and down play in the spindle. Three shims and I still had some up and down play, but four shims seems little tight. I am wondering if I should remove one of the shims and sand it down a little bit, so that the PS spindle moves as smooth as the DS spindle. Do you think that once the truck is driven a bit it will loosen up a bit on its own?
When installed can the spindle be rotated without much resistance?
If too tight I would hand lap one of the thicker shims on a sheet of sandpaper.
Once your assembled and on the ground the thrust bearing will seat better in the beam and spindle allowing for more clearance. I would rather have it snug than loose. Lube on a regular schedule.
