Front Differential Fluid Change - Polaris Sportsman 

Great Video I never did the 25hr check until now. If I could go I probably would have waited to install winch and front bumper. Very tedious and time consuming but well worth the $250.00 charge at the dealers to change all fluids. Knowledge is Power!!!!!!

You can get to the fill plug from under the front and don’t have to remove the winch. As for the front bumper, it would depend on your front bumper.

You can remove the bolt without removing the winch. Remove the lower screw on the plastic face that's inline with the bolt. Peal the plastic back a bit and you can fit a 10" 1/4" extension to the bolt. Use a 1/4" to 3/8 adapter since the 8mm hex bolt is probably in 3/8 drive. There'll be plenty of play in the connections. You can also try a flexible extension. 3/8 extension won't work as there's a bracket in the way. The 1/4" extension is thin enough to get past the bracket and have an almost straight shot at the bolt.

When winch is in the road. Just drain from bottom plug, flip quad on it's side and re-fill differential oil in same bottom plug. Takes exactly 1 quart 75W-90 hub oil fluid. If you are doing it at the same time as an engine oil change, it's best to empty that engine oil first. Keep engine oil empty until you refill front differential and flip quad back upward. Makes it a 5 minute job. Then finish your engine oil change last.

FYI I was able to access fill hole by cocking the winch forward (right side) without disconnecting winch conections

Demand drive fluid is for the front hubs only. The front diff uses angle drive fluid or a 75-90 gear oil.

Great instructional video … most appreciated

Thanks man, helped a lot! I found you by the search for diff change and I’m from Freddy differently a new subscriber😂

Definitely helps “OWT” 😂.. just kidding… Great video

When would the next oil change be? And if it was not ridden very much, would it still need a change at a certain time.?

Nice looking off road lights where did you get them from?

Okay I might be dumb! but how do u tell the difference between the front diff plug and the oil plug? Trying to change oil but don't want to drain the wrong one

I think I would you relocate the fill port Maybe using tubing that’s threaded And malleable this way you wouldn’t have to takeoff the winch and everything else... just a thought...I can’t help myself as a machinist and fabricating retired

I wish I didn’t have to remove my winch

quick question is the rear diff a separate unit or does it get lubricated by the transmission fluids?? I can not find a video or any instructions on changing the fluids in the rear diff on a 2015 570 sportsman.

Every 1000 miles I forgot to do mine and I'm at 1500 I know what I'm doing this weekend

what size and type tires are you running on that 570? thanks.

Is the rear just a transaxle

What would happen if you never changed the fluid?
