Was wondering how far to tear down the componets of the wheel to take for tire replacment. I'm looking at the spanner nut , an it appears to be tightened down for the purpose of preload on the bearing. Not sure if I want to remove if its posible, for the tire shop, to change the tire without it ,an the bearings removal. Plus I don't have the proper tool, and no service manual for the proper specs to re-set. Any advice would really help here
