Anyone know if there is a bushing for the pivot of the front axle? I seem to have developed a large amount of play that allows the axle to rock forward and aft about 1/16 of an inch....makes driving in road gear interesting. I haven't had a chance to take it apart. Can't seem to find a parts diagram for it but assume it to be close to the 80's ford 1710 or 1510 model.
