Great info, added the images for you.

Man that seems like a giant pain in the ass. Thanks for posting - I'm sure some members here will benefit.

That's so confusing. I say just take to the dealer..

not looking forward to the greasing procedure...

Yeah fer chur! Reading that was a massive centerlock turn-off.

Other than the greasing, this is not too far out of the norm.

Guys with traditional lugs--- you should be tightening with the wheel off the ground, as well.

Found this in you tube.
