I do have a question on the spindle nut... I tightened it, beat the hub with a mallet, tightened it some more (per youtube). Then I backed it off so that the spindle nut has mark lined up with the nearest indicator and slipped the two locking screws in. The spindle nut was just beyond hand tight at that point I'd say... Does that seem right?

Too lose I'd say. I torque front to circa 50 ft lbs, spin a few times back and forth, back off and torque to 30, back and forth a few more times and torque to 30 again, and similar process for the rear however go a bit lower on the torque the second time around, 20 ft lbs probably not a bad place to start.

Yes they're probably too tight according to various experts, but IMHO more issues are caused by wheel bearings too loose than too tight, especially with big power or big tyres. Runs the hub a few (less than 5) degrees C hotter than a hub set up by the FSM, but doesn't become loose in 5000km.

I've always found the factory spec for taper roller bearings to be too conservative and use the FSM max as a minimum. Bearings are cheap, spinning bearings on a spindle can be very expensive.

I just today dropped off my rear axle at a machine show for metal spray repair due to the previous owner spinning bearings on the axle. Unlike in Australia they are unfortunately not common and cost more than a crate of beer in this part of the world.
