Sincere Thank you for the link, exactly what I needed.
So is the seal, bearing, or bearing damaged and therefore the knuckle is pushed up through the axle knee?
My guess is the bearing key 14 in the drawing beenthere posted has failed. I would ALSO replace the seal key 13 and check both bushings key 15, since you will have it apart.
Also check the other side, since it might be close to failing too. This is the kind of repair I do both sides if one side failed.
Thrustbearing failed !
When setting up these tractors at its widest that axle tend to brake at the wheelbearings ! Do not repair it . Just replace it !
