4WD Tundras don't have hubs. The Tundra axles are permanently locked to the axle shafts and use ADD (automatic differential disconnect) to go in and out of 4WD mode. Not sure what you are asking.

That will vary from wheel to wheel. Are you talking about the stock wheels or aftermarket wheels? Why not just measure the center bore? My Ivan Stewart wheels were definitely less than 108mm which is why I changed to Helo Black Maxx 6 wheels which have a 108mm bore.
