You need new seals. There is a seal on each side of the trany where the axel comes out. There is also a seal where the axel goes into the bull gear housing. Replacing the seals on the side of the tranny is easier than the bull gear housing seals. You will need to support the tractor as you remove the axel housing. The seals are standard. I have replaced every seal and bearing in the tractor. This is what you call a learning experence. Be sure you take emory paper to the axel to smooth out any rough spots. The smoother it is, the longer the seals last Good luck.
