I would think so.  I have, as several others have reported, had the worm
gear get really gummy stalling the motor.  Others have used a shot of
WD40, I used 3in1 oil.

Lubricating the worm gear requires disassembly of the motor itself.  To
reassemble, you will have to mess with the business of getting the brushes
back on the armature while ballancing the whole thing in a rather awkward
position.  Recommend lots of patience.  But I and others have done it.
