You have found your lockup. That is the bearing ball retainer wrapped up in there. That bearing has to be replace. Bearings are not super expensive. You really need a thorough clean up and replace all the the bearings in what you have disassembled. That is bearing #59 on Hoye's drawing. The inner race of the bearing is still on the upper spindle shaft right below the steering arm. Yanmar Tractor Parts: 4WD INTERNAL
Looked up my invoice from Hoye back in 6-13-13 and I purchased $194 worth of parts which included knuckle seals, bearings, seals, etc. Mine was not near as nasty as yours. This was for both sides.
I didn't know Hoye did repair work?
