I have two rotors, a tailtwister and a standby ham IV.

I have an older Wilson self supporting tower with the rotor mounting plate at 
the bottom.

Here's the problem.
Same control box...
The ham IV will turn the tower with no problem, back and forth.
The Tailtwister balks, some times it's turns, some times it stops part way.
It's not a brake issue as I hear the brake release, and it starts turning then 
it just 
runs out of gas.

It's not an issue with the tower binding as I can remove the rotor and EASILY 
TURN the 
tower by hand.
I do maintenance twice a year, it has multiple grease fittings on the large 
bearing the 
tower rotates on.

Same rotor control box, same cable to the milspec connectors on the rotors.
They both indicate the same.
It's just the Tailtwister that has started weakening..

Any suggestions before I open it up?

I've done normal cleanup and bearing lube before.

Sarcasm is just one more service we offer.
