MY son in laws c.c clarke has a seized steering system ,we have pulled out the steering mechanism and cable in one piece and i still cant see how to get the cable out to see if that is what is causeing the problem or if it is the part that the steering wheel attaches to ,are they one piece or is it possible to disconnect the cable at the steeering end the main bit at the steering end says not to disasemble just replace it. Does anyone have any useful info on this problem or do we have to replace the whole lot the unit is about 13yr old thanks in advance for any help ....matt
