The axle wobble sounds like either a loose wheel clamp (the four around the perimeter) or a bad bearing. You'll want to get that fixed since a bad bearing will misalign the bull gear in that housing and (eventually) cause the bull and pinion to destroy themselves and chew the whole final drive up on that side. You don't want that to happen.
Bearings are all universal on it, there is nothing odd or special that you cannot get matched up.
Make sure you add oil in that final drive. They usually have been neglected through the years.
Thanks for the info, I'll look into the axle, I was going to check the oil in the rear end anyway, when you shift gears it sounds kinda "hollow". I don't think the PO took very good care of the old thing, for instances, he never put on the hood, grill and ect. It seems like if it wasn't a important part to make the tractor run, he didn't bother putting it back on after he took it off. He also fluid filled the rear tires with water, so I will need to ad anti freeze before this winter. He also ran the old tractor pretty hard in his garden and it just blows oil out the exhaust. I fired it up the other day on the trailer, after running for less then 2 minutes it had a 5" around puddle of oil on the trailer that was leaking out the manifold.
I haven't even unloaded this tractor off my trailer yet, I'm going to take it back into town and give it a good washing. There is a lot of old oil/grease all over the poor old thing. Once everything it fixed up on it, I'm going to get it a coat of paint.
If it is a bad bearing, any idea on how deep I half to go to get to it? I was just wondering if I'm needing to pull the whole rear end apart or not.
Thanks again for the info
