steiner 415

Hello all, I have a 415 Steiner and the rear axle seals are leaking. Is this an easy fix? can it be done without dis assembling the complete axle assembly?

I am in the market for a tractor and came across the Steiner 415. Looks like a well built machine. The Steiner dealer in my area is willing to take my Power King(1212) in on trade(have had a difficult time trying to sell it outright). Any thoughts/opinions on the Steiner-I need to move some...
