Also, with OEM axles you can replace the inner CVs, but to get new outer CVs you have to buy a whole new axle. (Or was it the other way around?)
Either way, by the time you look at buying a new axle, you're better off going to SuperATV Rhino 2.0 axles. They're stronger, have a lot more flex in the CVs, and you can buy replacement CVs for inner of outer as needed.
