Yup, cracked jockey wheel(pooey stinko), the kind with bearings rather then bushings. Just ordered a NOS set through Ebay and hope I am not getting screwed by the seller(promised to refund $27.00 US of the posted $34.00 cost to ship - we'll see but I do tend to trust first and grumble second).

Update on the seller of the jockey wheels. He sent the refund within minutes of my making payment. His selling name, on Ebay, is weinniroaster. Normally, I would not post someone's identity without permission but this is a different case. His efforts to help me out is noted and appreciated.
