Here's an image of the rotor/stator being cleaned.....apparently this motor is used in a few Nikkor lenses....
..the AF-S Nikon 28-70 2.8, AF-S Nikon 80-200 2.8.... and the Nikon AF-S 17-35 2.8........which is handy to know.
In general these motors do not go wrong......other than "micro surface corrosion" .....given that the lens hasn't had a fall or a bang...........the owner assured me that the lens hasn't suffered any fall and that motor was slowly dying, then packed up altogether!
