I'm about to raise a 72' US Tower equipped with a pair of TB2US thrust bearings spaced about 3'.  I'll be using a TailTwister2 Rotator.  Is there a procedure for centering these components to preclude binding?

I doubt there is a way to make the two bearings share the vertical load, so which one should I choose.  I'm thinking that the top bearing should take the load and use the lower bearing to stabilize the mast laterally.
