Where the kingpin goes through the wheel support, it is pinned in place with the lock pin, so it is not a rotating part. Only the spindle rotates, and the kingpin is static.

The bushings in the spindle are supposed to be reeemed out to .866, if using the standard size kingpin. So I am having a hard time visualizing that .001" difference in the wheel support bore would cause significant play especially after being pinned which essentially wedges the kingpin against the opposite side of the bore.

So that being said, if the kingpin is "wobbly" after being pinned and the wheel support is indeed oversized or the kingpin is undersized, then an option would be to have a machine shop install a metal sleeve (or a speedy sleeve) at the top and bottom to make up the difference (leaving the lock pin hole clear). That would solve the issue. Since the kingpin doesn't rotate in the wheel support, a steel sleeve can be used as it doesn't need to act as a bearing surface.
