Why is there trans oil leaking from where my axle meets the wheel

[Zachary Kosinski 1]

This wheel horse has sat for a while and recently pulled it out of its hole. It has the 8 speed transmission but recently started leaking out where the axle meets the rim (shown in pic). Obviously something is wrong so my question is what needs to be replaced?

Obviously something is wrong so my question is what needs to be replaced? My guess is the hub went bad. My reasoning for that is the other one seems to be newly replaced by previous owner.

Left something out

You have an axle seal leaking. May be due to old age, sitting or worse bad axle bearing causing the axle to squash the seal.

Probably just a seal, but I’d drive it a bit, clean it up, then see what it does… my guess is you’ll be putting a new seal on it…

As wet as that looks, you shouldn't have a problem getting the hub off   Once it's off check the keyways for wear.

I did a little looking. You seem to be right! Do you know where I find can find one or if you know the part number? Thanks a lot

Is that a 1" or 1-1/8" axle?

1”

[rmaynard 14,945]

1" seal is Toro 100863 or local auto parts store SKF9815

Your hub may also be loose.  The outside should be flush with the end of the axle.

Welcome @Zachary Kosinski Zachary!... looks like it needs a seal at least. The hub shouldn't be so far in on the axle so take a good look for wear in that area. Good luck

My guess would be the hub has been rubbing against the seal and has torn it. The set screws should be torqued to 35 ft/lb.

When you jack up the rear wheel see if the axle bearing is causing the seal to fail. If the axle moves in and out a quarter inch or so that is fine. If the axle moves up/down or front/back then the axle bearing is bad and would need replacement.

Turns out the keyway is worn so the only way to keep it tight is to have the axle sticking out

Don’t keep running it, a loose hub or bad bearing will cause additional damage.  Jack it up, remove the wheel and hub to inspect.

You can fix the axle and hub so it doesn't slide and sits where it should be.
