Well, if you look back up this thread you'll see where I listed all the parts to use the XP900 steel hubs...

Not the cheapest, but it gives you the latest bearings, steel hubs and all the parts to install without finding yourself without something!

Is this directed toward me???

 

[Pirate]

Nope, just saw people looking at other options and thought I would comment again that there is a fix that can be done with no guesswork whether something will work.

Just sayin'

I agree with you there Stuart. I'm gonna use the xp900 front hubs and parts. My main goal is and has been to come up with some steel rear hubs for the 800 to go with the xp900 front hubs. I'll know for sure how the 570 rear hubs work in a week or 2.

 

[Pirate]

Best of luck on the rear hubs.

Can't say I've ever had a problem there, in better that 9000 miles.

Have you had a problem? I believe that when Polaris upgraded the bearing in the rear hub, the carrier didn't change. The front hubs, when Polaris upgraded the bearing you had to have the new hubs as well.

No I've never had problems with the rear. I know people that have, but most were from rolling the rzr on it side. I'm considering going to 30'' tires soon, so I thought it maybe a good idea to upgrade the hubs too. I dont ride too rough, but if I need to hit something hard I dont want a broken hub to ruin a ride either. And me and the wife do alot of riding alone, so I like eliminating any weak spots. I have broken 3 front aluminum hubs, but never so bad that I couldnt ride it out.

 

[Pirate]

We're like you. Do a lot of riding on our own.

I'm running 28.5" tires, and have been for about five years now...no problems with the rear hubs at all.

Unfortunately have barrel rolled it once and laid it over on the passenger side real hard...but no hub damage at all.

I think you could let that one go.

Now I did do as a post recommended years ago and drilled and tapped the bearing carrier for a grease zerk on the lower bolt. That seemed like a good idea.

I'm sure you are correct, I have put 2600 miles on our rzr in 3yr and had no problems with the rear hubs. And more than likely would never break one, especially since I tend to ride easier and take less chances every day that passes! Lol! But I found a set on ebay for a decent price and figured I would be the guinea pig and give it a shot. Seems like anytime there is a thread about broken hubs, everyone always asks if the xp900 rear hubs will fit. So if the 570 hubs work we will have an upgrade for the rear to go with the xp900 fronts.

 

[sheriflittle]

i have an 09 800 are you saying ya cant get a replacement bearing for the front?

 

[RMR Man]

2204717 is the Kit that gives you the larger OD front hubs (stronger than the originals) and a larger ID bearing. You can't even buy the old original 2008-2010 small diameter hubs, because they proved to be weak.

 

[Clothier]

If I had an 08/09 that hadn't already had the newer 44mm OD updated hubs put on, I would seriously consider just going ahead and retro fitting the xp900 hubs. It will cost alittle more but You wont have to worry about breaking the front hubs. And I see you are planning to run 30" Carnivores Sheriflittle, That will put alot more strain on the hubs. Just my opinion. Oh and as I said earlier I've broken 3 front 800 aluminum hubs. Not from rough riding either, 1 from bumping the passenger front tire into a tree, not straight on either, just rubbed the sidewall enough to put alittle bark in the bead area! The other 2 I have no idea what caused em? Didn't know they were broke until I was doing maintenance and felt play in the front wheel, thought it was a bad bearing until i pulled the hub off and part of it stayed in the bearing!

Correct. You have to buy the new style bearings and updated hubs. Unless you can find some NOS bearings but good luck!

Jamie,
You can get a replacement bearing for the 08 RZR (take old one to bearing supplier to match).
The original hub has been superseded.
If your hub breaks, you will need to buy the stronger hub the bearing that fits it.

I already got sum newer 570 rear hubs on the way to try out. I havn't had any problems with the 3/8" studs myself, so not too concerned with necessarily going with the ranger hubs. Only problem I could see with the ranger hubs vs the 570 hubs is if a person is running the oem crusher wheels, I'm thinking the bolt holes are too small to fit over the 12mm studs.

Brian,

Does this mean you will have 3/8 lug nuts in the front, and 12mm lug nuts in the rear?
If your new hubs come without studs, could you measure the holes in the them?
There may be a 3/8-24 stud that would press in.

No, sorry for the confusion. I should have given more info there. Rush2252 and I were discussing some take off Ranger hubs his friend had used. Those particular Ranger hubs have 12mm wheel studs. The hubs I am getting to try(and am 99.99% sure will bolt right up, I will know next week sometime) are rear hubs for a 2014 to 2017 RZR 570. They have the same part# 3/8" studs as the RZR 800 rear hubs. The differences are that the RZR 800 rear hubs are aluminum and use 4 - 3/8" O.D. bolts to hold the brake rotor on where as the RZR 570 rear hubs are steel and use 4 - 10mm O.D. bolts to hold the brake rotor on. But both use the same wheel studs. Hope that clears it up.

 

[CA 800]

Yes, that clears it up.

Did you order partno 5139163, HUB, WHEEL, REAR [EAI][EAW]?

 

[Clothier]

Yes, that clears it up.

I actually found a used set on ebay, but yes that is the correct part #. The thing you have to be careful about is the 2013 RZR 570 had the same front hub and same rear hub as the 2011-2014 RZR 800 which are aluminum. And on ebay alot of the hubs listed for the 570 are the aluminum ones. Some even list the aluminum hubs under the steel part numbers! So you have to really research what you are buying from ebay and such. Now if you go to the dealer and ask for part# 5139163 you should get the steel hub, but you will still need to get part# 7519343 rotor bolts to do the swap. You could re-use your original wheel studs.

 

[Clothier]

Ok guys, I installed 2014-2017 RZR570 steel rear hubs part# 5139163 and rotor bolts part# 7519343(these must be used to do this swap, as the 800 uses different rotor bolts), these use the same rotor and wheel studs as the 800's. I've been looking for an upgrade for the rear aluminum hubs since I have owned my RZR. Also did the XP900 front steel hub upgrade, hub part# 5137659-067, rotor part# 5254999, rotor bolts part# 7518978 and wheel studs part# 7517871(all of these XP900 parts must be used to do this swap). All worked perfectly and an easy upgrade! Here are a few pics of the rear hubs.

Installed on RZR





Sorry I didn't take any pics comparing the front hubs or install, I figured they have been covered before. This should stop any and all of my hub breaking!

 

[Pirate]

I dunno Brian, looking at your Avatar pic...go driving like that...and now have steel hubs...what can break next? Aluminum bearing carriers? Axles....

We'll hope nothing!!!! Good to feel like you have something "bullet proof" tho doesn't it? Always my goal...bullet proof!!!

Pirate

 

[Clothier]

Yea it's always my goal to have it as buletproof as possible but still have a cheap easy to fix weak link. My wife keeps me from driving like an idiot these days, well her and my wallet! Funny you mention the avatar, it looks deceiving. I was actually just pulling up a short steep rock ledge, just boucing the front wheels off the ground. After the picture was taken I backed down and never did actually climb it! Lol! I didnt see the need to risk breaking something!
