Sprocket and Rotor Hub Grooves

My axle got a little play in it after my last trip to WV. I pulled the carrier out and to my surprise, only one bearing was bad (it was toast, but i still changed all 3). I guess I shouldn't be too surprised though, the machine is still on it's original 2007 brakes, chain and sprockets.

I am concerned about the sprocket and rotor hubs, however. They have some grooves that look machined in but i would assume the surfaces should be smooth and flat so the seals can have a flat mating surface to keep water/dirt out.

I found a replacement rotor hub on RMATV for ~$45 but it looks like the sprocket hub can only be replaced by buying a new axle. My axle is straight and I really don't want to spend $250+ because of these little grooves if they're supposed to be there or if there is a way to replace the hub separate from the axle.

Anybody have any insight?

i had the same thing happen the carrier bearings were toasted on one side on i just bought a new axle and the brake rotor hub and a lonestar billet rear carrier and it is the tightest rear end out of all of my bikes. It is just when the bearings wear out and get lose and wear those parts out i went with the dominator 2 plus 4 axle for mine around 500 for all of it but well worth it it can corner way better and looks a lot better
