cpt, the 08's have a smaller spleen where the shaft mates with the hub body and fail where you noted. Now I need to preface this with the front hubs, where mine broke.
If I were you I would do a part # comparison between say an 08 vrs 10 to see if they upgraded. If the 08 comes with a bearing,that means that they did upgrade the parts. If they did, I would order two sets to strengthen your other side,

I have the same thing on11 s...just found it tonight...i wonder if dealers keep those hubw in stock

SENT FROM MY DROID

 

I had the same thing happen on my 2010 s. Its cause the rear hub is made out of cheap cast... my dealer had them in stock and it was like $50 bucks. shows you how cheap they are made.

 

Man i hope they have em...i got a big ride this weekend gotta get this thing rollin

SENT FROM MY DROID

 

something tells me they will have them .. i sometimes think they build these "weak" parts to guarantee parts sales

only thing that worries me is this happened after I put in a lift to get some clearance wondering if the different geometry could have made it snap

spare partsbox for rides just keeps growing

 

Hummmm, looks EXACTLY like mine 2011S. RT Rear also.

 

anyone making aftermarket ones ???

not a part i really want failing where we ride

 

I know none of the dealers near me stocked hubs or bearing carriers for an XP that we needed during Dune Fest. Maybe they will stock the standard RZR hubs, I don't know.

 

mine broke on the front left,found a used one on craigslist ,but ordered a new set from polarisparts.com for when i break another

 

utv inc makes billet ones. fireball does as well??? but they are both pretty spendy!!!

 

I replaced mine with a new factory hub. I replaced both rear bearings with Timken Bearings. Thinking the bearing play that they always had even when new led to the hub failure. After replacing with the Timkens the wheel has no wiggle . Only time will tell.

 

do you have a part number for the timken bearings? thanks keith

 

On my 11s I broke about 4 stock hubs fronts and rears. Got tired of fixing them and my rides being cut short so I went with the UTV billet hubs. No more problems.
Stock ones are weak and if you ride hard at all you will break them, also putting on wheel spacers will put more leverage on them and they will break a whole lot easier.

 

510003 is The Timken bearing # for 2011s probably fits others

 

im still concerned that its something to do with the lift

mine broke after the first ride with the new lift

i am going to go back through it and make sure there isnt anything binding
