520H Wheel wobbles

[Capt Beak 0]

Was taking the wheel weights off of a 520H to change from blowing snow to mowing grass and I noticed the right wheel wobbles a bit, meaning if you grab the tire at 3 o'clock and 9 o'clock you can move it forward and backwards a bit. Does any one have an idea of what might of worn or failed?  How in depth is it likely to be to repair?  If I have to I can use a Cub Cadet to mow and take my time getting the Wheel Horse fixed right as I mostly consider it as a riding snow blower that I can mow grass with. Or to ask the real question is the transaxle/axle in the Wheel Horse easier to fix than the oil leak and steering in the Cub Cadet?

Check your hubs set screw?

If there is no oil leak on the side that wobbles, it is, as Craig has said either a set screw or worn keyway problem.  Rarely is it just a set screw and if the keyway has wallowed out the axle shaft, then it is a different repair.  If there is oil leaking out the side that wobbles, then you probably have a failed needle bearing.

About 1/8" in and out is normal...side to side and up and down is not.  Hub or bearing, like was stated above.  If it is a bearing, that requires dropping the trans and opening up...not a hard job to do.    Let's see what you find.
