morning , just about to start servicing my ferret, have you actually got a problem with your ferret pigdog?only saying this because when i grab hold of hub at 3 and 9 o clock position and move mine back and forth it will feed back thru steering arm ,if u can post a video it will help a lot,like previous poster said if u get someone or something to lock steering wheel in one place and then try to move hub there should be little or no movement.
