Going to replace the rear wheel bearings in my 98 Sportsman 500 today.
I hope replacing them goes pretty smooth.Most likely getting the old ones out will be the hardest part as usual im thinking.
Anyone remember what auto parts store bearings work?
I think i remember reading about some car bearings out of a Kia will work or something.

Let me know how this project goes, and if these are the right bearings. I have 2 units that will need this job eventually.

These bearings were great but the only downfall is that they're 53 dollars a piece

Use a cheaper brand bearing. Use a Carquest #B510003 about $21.00 each at the Carquest i work at.
Sorry I didn't see this post earlier.
You can also buy u-joints,belt, and front wheel bearings at parts stores.

I realize this is kind of an old thread. Didn't wanna start a whole new one. I will be doing rears on my 2012 800. Any tips or tricks to the job? Looks pretty straight forward.

Throw the bearing carrier in the oven, put the bearing in the freezer overnight and like polman500 said it will drop right in.

Do not beat on the bearings, EVER. Use a press and warm the nuckle just enough where you cant touch it. Do NOT get it cherry red.

Do not use Polaris bearings. Id use SKF or Timken. I just ordered a Timken from amazon here Timken 510003 Wheel Bearing : Amazon.com : Automotive

Do not over torque your axle nut and do not use an impact to tighten it. Use a torque wrench.

While you have the nuckle off its a good time to pop the rear axles out and pack the splines with antiseize. They rust pretty badly on Polaris machines and can make axle removal impossible in the future.

The Timken bearing I ordered was made by NSK. They are the bearing supplier for honda automobiles and yamaha ATVs. Just so you know in a few hundred miles where to get a good bearing :cowboy:

I will inspect it when I get it for sure, if I think it is inferior it will go back. Mine is not shot yet, but on its way.
