VPI Aries Motor noise

When i recently fired up my aries for a listen [it's been at least 3 years:-( ], i noticed some rotational noise coming from the motor.

It was quiet enough that i couldn't hear it from 3 feet away... but i was wondering if there was some basic user maintenance/lubrication that could be done. I don't see anything in the manual.

Figured i'd call VPI on monday, but in the mean time... anyone else have that issue or know about motor lubrication?
