replacing axle shaft and hubs

Kenockee 8N · Sep 9, 2016

Hi all.

I just bought a 52 8N and it has the wobble in the rear end. With some help from members and research on here, I've identified that this must have been an issue for a while as it had a 2 piece axle nut on it and both the nut and axle shaft are stripped.

I bit the bullet and ordered both new hubs and axle shafts for both sides and figure I'll get this done and out of the way so that it should last me the rest of my life (I'm 32).

My question is if the bearings on the axles look ok, can they be pulled and reused on the new axles or should I order new bearings?

Also, I've seen some posts where people say to make sure you pack the bearings. Aren't these bearings lubricated by the oil in the diff/hydraulic system/trans? Would it really be good to be packing them with wheel bearing grease that will then get diluted into that oiling system?

Pressed on and can be pulled without damage with right eqmt. 52 is new enough that it should have inner seals & if it does you need to pack as those inner seals keep the diff oil from reaching bearings.

Thanks for clarifying that. I could have easily burned them up if I didn't pack them with my thought process.

I may just order them and if nothing else have them on standby if I damage the old ones or just go new with the whole assembly.

hen I go as far as all that work, I replace bearings & seals as I don't want to come back soon.

Just ordered the bearings. You are very correct there. I don't want to get this far into the rear end any time soon.

The bearings can be reused if OK but if they have been run as loose as described for a long time, they likely will not be.

If your tractor is indeed a 52, the rear axle bearings are not lubricated by the rear axle oil and must be properly packed with proper bearing grease.

Of course, you will want to replace both inner and outer seals while it is apart.

Thanks dean. The kit I ordered has the axle, hub, inner and outer seal, felt brake seal and axle nut with clip. I've also ordered the paper shim set and now the bearings (both cup and cone).

On my 50 both rear axles are doubled sealed and there is a small screw you remove and squirt grease in the bearing cavity. Works great and both brakes are in the dry. Apparently it was dealer modified or some previous owner did it.
