When I removed the PTO shaft to replace the seal, I was also able to also fix a severely leaking and loose lift arm shaft. I did it by putting my arm in the large hole on the differential where the PTO shaft came out from. Using a long box wrench to hold the inside nut for the lift arm and had a helper tighten the outside nut with a breaker bar. There was no cotter pin on the inside castle nut on mine which likely allowed the shaft to loosen over time.
