I was working on my spindles and hubs this morning and when I go to put the hubs on the spindles they don't slide all the way on. When I measure them with the caliper,!the hub is .01 inches smaller, which I assume is why they don't slide on. I don't think I should hammer them on because no one else's threads mention having to do this. So the question is what should I do? Put some grease on the spindle, and tap them in place, sand the spindle down a bit, or something else?
