I'm a tad confused. Are you speaking of the play between the bearing inner race and the spindle? I'm not a geometrician good enough to figger the translation from .0004 at the spindle radius into displacement at the tire tread. I know it's more. Is it as simple as the ratio of the two radii? Or do I have to remember that old injun Soh Cah Toa stuff again and pull out the sine and cosine and tangent tables? If it's radii ratio, and you are running 31's, the ratio is 15-20ish. The movement at the wheel would be .006-.008, or thereabouts. Take out the feeler gauge set and look at a .008 blade. I agree it ain't zero, but to the hand, the movement of the tire wheel almost can't be felt. It feels like it want's to start to move, but you can't really feel the movement damped by the tire rubber. If you have a bare steel wheel bolted to the hub, you can just feel it if you have good hands.

That's what I mean by setting the wheel bearing by touch. You tighten until tightening more doesn't take out that last little tiny bit, then back off until it starts to wobble just a teeny bit more, then go about halfway back tighter for a minor preload. Align the locking holes to the closest index , pin it, and you are done. You did pack the bearing, right???
