Loosen the mast clamp and turn mast/antenna by hand.
This will tell you if there is a binding problem.
It will also tell you if mast/rotator are aligned as you will see the mast
Then still with mast loose, run rotator through is limits.
This will give you the idea where the problem is.

Subject: [TowerTalk] rotator problems
> Hi all. I have a ham IV turning a TH-11DX which has been working fine for
> over a year. Prior to that, it turned a KT-34A for about 10 years. When
> put up the TH-11DX last year, I performed normal maintenance on the tower
> including greasing the thrust bearing. Everything seemed to be aligned
> I haven't used the antenna for a few months.
> Today, I went to turn the antenna and noted that it works from about NW to
> East but that it binds up beyond these directions and stops turning. I've
> checked the rotator bolts and they are tight. The rotator makes all the
> normal sounds in the sectors in which it rotates.
> Any thoughts would be appreciated.
