VPI rimdrive squeaks


Has anyone else got or had a problem with a VPI rimdrive making a regular chirruping or squeak (in time with the rim drive rotation, not the platter).
Rimdrive is on my SuperScoutmasterReference, converted from belt drive.
I've tried ensuring the contact is as light as possible but no joy.
Silence if rimdrive isn't in contact with the platter, twice per revolution squeak from (I think) contact point when rimdrive engaged.
At 45rpm squeak is audible from 3 or 4 feet away. Less at 33rpm but still there.
HELP ! This is driving me mad.

My rim drive is dead silent. My problem is with vibrations from the motor assembly being transferred to the platter and then to the tonearm. I find that great care needs to be maintained not to twist the rust colored O-ring as it is installed on the large drive wheel. It must be as straight as possible to maintain the precise edge to the platter, or unwanted vibrations are transferred to the arm. While viewing the Nordost wire loop that extends from the arm proper to the junction box, I can get it as quiet as possible, however there is still a very slight motion that can be seen if carefully scrutinized.
Rateourmover....Actually the rust colored belt is an updated version of the original black belt. Also, the feet of the motor assembly has been changed to a kind of sponge rubber...the original ones were solid aluminum.
Hiendmuse...isn't that odd....VPI changed to the rubber feet on the motor assembly from the solid metal original ones to allow the motor assembly to slightly rock so as not to transmit any out of roundness of the rim drive to the platter. You're saying the pointed solid feet are an improvement?
...just remembered....I DID have a squeek when I first got my Superscout. I was told by Harry to lube the motor shafts which I did and never had any squeeks thereafter. I used the VPI lube that looked like oil that was sent to me.
