tighten the spindle nut while rotating the wheel until it is snug .Then back it off a bit now you should be able turn the nut by hand.Tighten the nut back up by hand if the pin does not line up then use your wrench to tighten to the next hole.Usually this is a very small amount. Once these bearings are seated they don't need to be torqued like the original roller bearings.
