Upon review, I think Rhys has the answer, the bearings have to be different. They fit on the spindle just fine and are correctly seated into the shoulders of the hub. Unfortunatly, I tossed the old parts and they are long gone. The parts are Volvo parts - they must have changed what the sizes were...perhaps an older vs newer difference or just a frustration. Nylocs are out and I'll add a washer or two to take up the slack. The hub is going on fine, it is seated in the correct location relative to the rest of the suspension.

Sometimes these little part differences are enough to make you want to pull your hair out.

Back to the brake conversion...
