Steiner 420 leaky axle seal

[Frank Sorbello]

My uncle has a Steiner 420. It has an oil leak out of the front right axle. Is this a hard fix for someone with a limited mechanical experience? Is there a Steiner Service Manual I can purchase to repair this myself? I don't have the money to take it to shop to get repaired and I would like to fix this myself if at all possible.
Why doesn't TractorByNet.com have a Steiner category like all the other brands.
Thanks

Frank

TBN has a Ventrac section--same as a Steiner.
