I have heard of the 14's doing this but not on the '15 yet. Which do you have? I read yesterday Polaris changed the front diff for the '15 and I am wondering if it was to solve this issue.

 

I have heard of the 14's doing this but not on the '15 yet. Which do you have? I read yesterday Polaris changed the front diff for the '15 and I am wondering if it was to solve this issue.

My 14' just started doing this yesterday...guess I'm going to have to tear it apart. I've never had to tear into anything like this. Are there any seals or other things I should replace while I have it apart? Anything I need to pay real close attention to?

I would also like to know exactly why Polaris changed the differential (if this is indeed so beyond the sprague 'mystery') and what parts are involved (if you are somebody who simply replaces everything wear-related) 'if any' in doing the spring pin replacement.

Thanks.

 

I have the 15 just got it 2 weeks ago

 

I've read that changing diff fluid will help but what fluid to run?

I had the same issure...turned out to be a sheared spring pin on the ring gear. Very easy repair and i can finally spin them freely in 2wd without the terror of self engagement. hopefully your issue is the same cheap repair.

 

XS speed thanks for the tip! Exactly what I have going on. I'm originally from Eau Claire.

a buddy's highlifter started doing that on the last ride.

 

My 15 xp4 does the same

 

My 14 front diff self engaged, polaris replaced the front diff and it was good again.

 

My 2015 high lifter started doing this at 85 miles so I guess I gotta take it back in 2nd time in 5 days of owning it first a axle and now front diff! Starting to feel a little unsure about my purchase.

 

The pin in the diff is broken when it does that. Most likely it had also junked the carrier. I have 14 year models that have the aluminum carrier, they say the 15's have a plastic one on the early models. Idk if Super Atv had the replacement for the 15 yet. Hope it's still under warranty bc if you have to buy a polaris one its expencive...

 

Yea it's under warranty

 

My early 15 started doing this at 63 miles. The plastic carrier had busted completely. I actually broke it on the second ride I did with it, but didn't realize it until the third ride.

About 30 miles later it was making all sorts of noise and randomly engaging/disengaging. I bought a replacement 2014 differential and swapped it in.

Took it apart and yep, destroyed. The housing is still good though.
