Sportsman 850 Xp Rear Diff whine

johnb · Dec 21, 2009

When I'm driving about 10 mph theres a loud whine coming from the rear diff. It sounds like a honda civic backing up at 20 mph. Actually more like my 38" super swampers on my Chevy Blazer going 70mph.
Don't know if this is normal or a problem. Does anyone elses make this noise or found it a problem? . . . . I still have stock tires on it and it makes same noise on road, grass, mud, etc.... Thanks for any help

Ive read on the forum of clicking sounds coming from the reardiff, they were bad axles, some guys got them replaced. if your under warrenty get your dealer to look at it.

If I think I know what your talking about ours has done it since day and ours still runs like a charm with well over 1500 miles on it but, if its still under warranty get it to the shop and see what they can do for you.

Cool. I think i've heard a couple on you tube do it too. Guess I'm gonna still bring it in so they can check it out. Got a extended 2 yr warranty..... Shoulda just got a Snorkle! It would probably save me more money in the long run

do not waste your time taking it in it is normal. it is the cut polaris uses on the gears that make the whine. other quad companys do the same.my 800 outy was the same way.
