I had a RZR come in the shop last year with a front wheel locked up. The owner said a friend of his just put new wheel bearings in a couple months before and he couldn't figure out why it had failed so soon. When I took the wheel off it was obvious to me that his friend had tried to force the thing back together with one of the old races still stuck on the hub. He'd spacered the brake caliper up so it would align with the disc and it had all come apart locking the wheel... VERY DANGEROUS!! The guy was lucky it didn't happen at high speed or it could have been a disaster.
Holy crap! That's scary and sad... When I tried to put it back together without noticing the race was stuck, it was obvious that something was wrong. In today's day and age of the information highway and knowledgeable guys like you willing to help, there's not much of an excuse for that one.
As far as my situation went, you nailed it. You can't really tell unless you've seen it before or know what to look for. The grease makes it just look like part of the hub. Even without grease you'd be hard pressed to tell. I've done a ton of bearings in everything from my 69 Camaro to my F350 and several Harleys. Even Minis and a Benz. I've never run across the split race before though. I have seen bearings weld themselves to an axle on a trailer once or twice though when not greased.
Most all atv's use a double row ball bearing with a split inner race nowadays Hawk. You can get bearing greasers that slip over the axle and into the bearing so it doesn't have to be removed from the machine. They seal around the outside and pump grease through the split between the inner races to force out water and dirt and make your wheel bearings last way longer. I pump them full when new and then give them a few pumps anytime I have the wheels off doing something else. That's one of the first things I did to my new 1000 Sportsman when I got it home. New wheel bearings only have barely enough grease in them to prevent rust while in storage. Before I started greasing them, my machines would need new wheel bearings about every year. Now I do put a LOT of miles on in some really rough and often wet terrain, but according to where you ride, if you grease them a couple times per season you'll hardly ever need to replace them anymore. If you ride a lot and especially if its wet, the bearing greasers will pay for themselves within the first year.

Great advice to deal with maybe a not so great design. They're 35mm and 44mm front and back right? What do you think about a cheap kit like this: https://www.ebay.com/i/223455430363?chn=ps
I know the prices on them are all over the place, but it doesn't look like there's much to them. Would something like this be good for a backyard guy?

Yeah, the cheap ones work just fine. The more expensive ones have more grease ports. The cheaper ones only have one. You just need to put it in... give a few pumps... turn it about 1/8 turn... few more pumps... turn again... etc. etc....
The more pricey ones have multiple ports so you don't need to turn it to thoroughly grease the whole bearing. They grease all parts of the bearing at once. I have both types for different machines and its just a matter of knowing how to use the particular tool you have. They both will do the job if used correctly.

I bet I can machine a few more ports into it. Might not be worth the trouble though. Thanks again for the info.
