Anyone hearing anything about DIFF improvements on the ATV's. I know the XMR diffs are stronger than the regular one's, and Gen II's are better than Gen I's but they are still having issues. When are we going to see them fix the problems? Needle bearings, larger hubs in general etc are all a good thing, but it is the Metal problem with heat on the ring gears that still are biting us. Just make it stop, or I will by taking my dollars to a competitor. Something I said I would never do....

 

Haven't heard anything personally. Anyone?

 

Don't get me wrong... I love Can-Am. Used to race flat track on one. Also Used to only own Ski-Doo snowmobiles back when I lived in real snow country. Would never ride anything else, and made a lot of yellow snow.. (Old timer joke) I bleed yellow blood. That is why it kills me to see this happening. There are guys out there making a good living re-building the diffs. That is a red flag to me. The problems with the ring gears, bearings, seals etc are pretty consistant. All point to heat, AND wear patterns related to reversing. It has to be costing a ton of money replacing them on warranty. Not sure why this is such a hard nut to crack. (Buy better steel and heat treat the gears better?) For the premium price we pay for these things, we deserve a better product.

 

I personally haven't seen that problem. Squeaky rear suspension, whiny transmission, yes. For years, at least up here in New England, Polaris ruled the roost for 4x4 quads. Seems to be a shift to Can-Am. I haven't found either to be any more reliable than the other.

 

I've heard that it's a backlash issue that's causing the rear diffs to blow apartment on some Outlanders and renegades. I've also heard that it's an engineering default, NOT a assembly issue . Only solutions so far seems to be changing to a XMR rear differential. Still, most people seem to not be having an issue. I've been lucky so far with my 800r.

 

Yeah that is what I am hearing too. The ones that are failing are the guys who really push the limits in mud, Muskeg riding, have the throttles pinned all the time etc. which is causing heat buildup, and guys that are running larger than stock tire combinations. I think you are right, the way to go is to get an XMR. Lot's of guys get the XMR, then swap for less aggressive tires. Don't seem to have any issues after that.
