If the bearing is full of grease you don't need to worry about water and mud getting in with normal driving. No grease as it comes from the factory will fill up with mud and water in no time, guaranteeing a bearing replacement coming soon. The 2020 570 sportsman takes a 35mm on the front and a 40 mm axle on the back. Use red tacky grease and once a year is all that is needed.

OMG an actual atv how to video that is well done! Thank you!

Ok I'm really glad I found this video. I just got a 2022 sportsman 450 and the manual says it has sealed bearings. So does this still apply?

I love this bro!! Ur amazing Thank u so much!! Love the organization

Greasing every ride is overkill. You're doing more labor than just replacing bearings yearly. Lol.

Aren’t there sealed heavy duty bearings available now?

Super helpful, thanks!!

i use a 90 degree zerk fitting helps !! and a long straight hose too

excellent video!

Great video....! Im interested in all aspects of service.

I like my 2002 500 it has wet bath hubs no water issues ever ….. don’t forget the steering zerk under the headlight pod assembly ….I’d use Polaris purple grease or Amsoil grease

Thanks for the video 👍

Is this the same procedure on a 2008 sportsman 700x2

Very good

Is the sportsman 450 same foot pounds for the Center bolt? 75fp?.. I need to do this

Is it the 40 or 44 mm tool?

How do you grease to back one? The one without the brake!

Would you do a sportsman 700x2 efi 2008 the same way

Does all this apply to the 2024 Sportsman 570 eps as well? Or did they change something?

Yes other videos please....how to change out a wheel bearing. Do you just grease the fronts only or all 4(6) in my case 6x6 big boss 570.

are the 2010's the same? i have a 2010 Sportsman 850 & i've never greased the Wheel Bearings.

Is sportsman 450 ho 2019 35 mm front 40 mm back

How do you clean?

What tool size for 2018 570 ?

How about the rear?

I also can’t find any grease fittings but the one on the prop shaft, any idea where they would be on a 2021 sportsman 570? Thank you for the video, it was very helpful

I have a 2021 570 sportsman, can you share a part number for that tool? Thanks for the video it helped a lit

What mm are front and rear size tool? 35? 40?

you make some great videos man. i have a 2016 850sp but all the same idea. I have been dealing with clunking into reverse or high, almost when the clutch releases, sounds like either slop in the driveshaft or coming from rear diff. Im lost, the machine only has 50 hours and 400 miles. Any ideas?

I have a used 850 and i noticed one of the rear wheel bearings was installed with the removable race to the outside. I greased and reinstalled do you think its a big deal? Or should i change it?

anyone gotta link for the grease tool??

Did you replace the pinion cover? If so can you post video of how to?

Good video man! Do you know if the 570s are the same?

Where can i found that tool ?

I ordered a Polaris 850 Premium Trail model, should be here the first week of August. Can you provide any information on where to purchase the greasing tool? Thx in advance....

What size tool do you need for a 570/850 sportsman 44mm and/or 40mm? Thanks.

might as well use water proof grease, much thicker !!

What is the cleaning stuff you used?

Link to tool

that bugs me, just bought my wife a 23' Polaris 450 and that seems ridiculous to not have sealed bearings.

I highly doubt most owners ever grease their machine properly.

You're over greasing for there to be that much grease thrown up against the jnside of the hub. There should be barely any visible grease coming through the seal/dust covers.

Way too excessive. I'll just replace the bearings when they go lol

You do this every single ride? Geeze just grease them every 6 months and replace 1 when it needs it. You're doing way more labor and cost than just replacing then when needed

Why I would never buy this quad. It's junk ! A cfmoto is a better unit then these. Sad !

Piss poor Polaris…
