After market axles…experience or ideas?

Seems like one of the rear axles on my 14 Sportsman XP850HO has some issues.
It is not rotating at the same rate as the other axle. I turned the hub by hand and something does not feel right. Broken CV joint or busted axle. I have not torn it apart…yet.

Has anyone had any experience with aftermarket axles?
Polaris wants $330. Others are available for lots less. Ya know…that long river in S. America!

Ideas? Experiences? Comments.

Thanks.
