gen 2 can am anatomy of a rear diff failure

i wanted to make this video to show how these diffs fail. more importantly why they fail. they do not blow up because of reckless use of the throttle. axles should break long before a diff ever does. these failures start right out of the box. the pinion teeth wear thin to the point that they cant handle the stress and then break. if you dont believe me just drain your oil into a clean pail shine a light on it and look at the sparkle. all those tinny little fleck of metal come from some where, and its the pinion teeth. i have eliminated this problem of rapid wear, now the teeth wonnk break and the case will not split apart anymore as the broken teeth fight to stay meshed.
i will be making more vids in this series please sub like comment and share

I just ordered from you guys. My pinion bearing is hosed and she took on water due to that wearing out the pinion seal. Lots of recommendations to buy from you guys.

[@destrik]

Broke my rear right axle from being stupid and forgetting to take my parking break off and driving away, hoping my diff isn’t screwed also, guess I won’t know til I take her apart.

[@mmmcquoid]

the outer housing has got to be flexing if those gears are shimmed proper .Its the only part of the equation you have not shown .did you file test the gears to see if they are hardened?

[@mentalvmaxrider]

Gears aren't heat treated,they're face hardened. Improperly worn parts don't get pitted,it's called galling. Pretty simple fix....ink the gear tooth pattern and adjust backlash. There's no preload to set as they are ball bearing and not tapered roller.....which it actually SHOULD have. If you can find tapered roller bearings to fit the case you're golden.....that diff should last a lifetime. No secrets here,a diff is a diff and since you didn't mention any fixes this video was a complete waste of time.

[@mudNwheels]

oh the things you learn when you have rpaired more than 3000 of these

[@mentalvmaxrider]

@@mudNwheels they're the same as any other gear set. There's nothing magical or unique about it. Can am,jlg,cat,jcb,chevy,ford,dodge....the principal is exactly the same.

[@richardkertz7848]

Nice video. These machines are like work trucks. Need the oil changed more than normal in the differentials. They get abused. If you read up on a rear differential rebuild you are supposed to change the oil just like engine oil after heavy pulling. These ATV with people and in the mud basically haul a load all the time and not to mention larger tires. Most of that pitting is heat and makes the teeth brittle till they brake. Pattern was consistent enough to make a clear mark. So if you want your stock Diff to last then change the oil on a routine maintenance.

[@mudNwheels]

+Richard Kertz thanks for the comment, and you are right about the oil. but these diffs still have issues to this day. i have been fixing the g2 diffs for over 2 years now and had an amazing success. facebook.com/Mud-n-wheels-672787052788976/

[@richardkertz7848]

I haven't looked into my 11 Can am 800-XT. I checked the oil in the past for water by removing the fill plug and it all looked good. After I read this I changed mine but I have 250 miles on mine. Probably no time for wear anyways but thought more about it bc I have 28" Zillas so I changed my oil and no metal fur nor contaminants. Looked like new oil draining out. Went with 90wt Royal purple for now. Will check every 50hrs with oil change to see if any metal fur shows up this time.

[@mrjay4000]

Richard Kertz, hi just reading about these issues as I am looking at a used 2011 800xt and a 2012 Gen2. I understand only 2011xmr were Gen2? Then I read about the Gen 1 limp mode issues and I may just stay away from Can Am. I am thinking you have the Gen 1. Any limp mode or over heating issues? Any advice? Would you buy the 2011 or 2012?

[@ryanb2392]

Please tell me where I can get this issue fixed on my Outlander 1000R that I just bought. I do not want this issue to cause me problems at all. What do you recommend to fix this before I have to experience this very bad issue??????? Thanks - Ryan😁

[@mudNwheels]

+Ryan Bevil hi Ryan Bevil these diffs have gotten a little better over the years yo have brand new machine so ride it have fun if anything happens you should get warranty. should you ever need my services yo can check my out on facebook plus i will have a web site in the new year. you bought an awesome machine enjoy facebook.com/Mud-n-wheels-672787052788976/?ref=hl

[@TheShooter466]

I got a 2015 outy 500L that's got some kind of noise that sounds rod knock but comes from the rear diff area any idea is this diff related or drive shaft related? We just bought it for my GF and i want to make sure it's a solid bike before we do any big trips with it.

[@pieterpieterse2347]

Hi there my commander 800 2011 makes a winding noise while driving ,on the lift sounds like its coming from the gear box.is it normal? i got it now for 2 weeks

[@randallnevels229]

Question ??? My can-am 850 2017model sounded like something broke when I hit the gas in two wheel drive and I heard cling like someone broke then it wouldn't move in two wheel drive but if I put it in four wheel drive it would move but feels like the rear in in a bind it kinda squats when it moves!!! But will not move in two wheel drive!! What's your opinion on what broke ???? I'm not sure were to start to look for the problem !! Any help will be appreciated thanks

[@napieraustin]

Can you replace pinion bearing pretty easy?

[@FrankiesChannel]

Nice work!! I haven't had any issues on our 2 machines but very curious myself on a solution. Do you think this is the reason Can Am changed the oil spec from 75-90 to 75-140.

[@mudNwheels]

Affatato's Channel i think it is the other way around original spec was 75/140 now it is 75/90. i know i have had better luck with the 75/90 myself. hope you have better luck with diffs than i did. what year and size are your bikes? thanks for the comment

[@FrankiesChannel]

Both my machines are 2012. 800 & 1000. I thought 75/90 was original spec and in 2012 they changed it to 75/140. So is Can am back 75/90 now? Dam I just stocked up on 75/140.

[@freddyw4555]

Drain plug magnet must have had lots of metal on it

[@zacharyfineman7620]

Can you put a gen 2 crown gear in a gen one case ?

[@bradenpompu9702]

Had a 2011 xmr 800 for 6 years. Over 400 hours on it. Never a diff issue ever. My 2017, same thing. Have had it for 3 years now, never an issue. I run aftermarket clutches and 31 inch mud tires. Dont understand why you have this issue all the time. I ride hard too. Very weird

[@revo3423]

i have a 2014 can am outlander xt 1000 has about 10-15 hrs n the rear diff cracked n cause the load to go to the front n ended up breaking front axel. took to local can am shop n after 3 days can am said good luck fix it urself not covered. i had it n mud! did i buy a money pit??? i did not abuse it.

[@mudNwheels]

i have heard this story so many times. i hope can am starts to listen to the customer. bad news is your going to be out some money, good news is that this problem can be fixed!!! if you are interested contact me on face book facebook.com/pages/Mud-n-wheels/672787052788976?ref=hl

[@FTORC1]

revo3423 According to BRP, the 2014 lineup came with a newly designed differential, with spiral cut gears, instead of the straight cut gears in this video. They went that route, because it was quieter. So, this wouldn't actually pertain to you, as yours is more like the gen 3, rather than gen 2.

[@mudNwheels]

FTORC1 the xmr 1000 has helical gears. the short outty and renegade 2012 to 2014 have the same diff with bevel gears. in 2015 the regular g2 diff was redesigned but still with the same style of bevel gears. so far i have rebuilt to 2015 g2 diffs. the problem that i correct with my rebuilds is still there

[@RobWall1218]

my front diff is beginning to make a rubbing or grinding sound when the visco lok kicks in. I wonder if it's the teeth breaking? diff seal maybe?

[@Blackford86]

Do you make rear differentials and front differential for a 2021 renegade xmr 1000

[@joeperez3081]

Hello, good video and I have a question for you. I have an outlander L 450 2015 and in the manual says to use 75w90 oil in one Axle and 75w140 in the other and I live where is really hot all year round so my question is if I can use just one of both oils in the 2 axles and wich one would it be in case is positive. Thanks.

[@mudNwheels]

hey joe i recommend 75/90 year round in all climates even to my customers in tx and fl

[@joeperez3081]

pls sir i live all the way in lebanon middle east and was seriously considering buying a 2017 xmr 1000 outlander atv it costs 21k here...ya. but after this vid idk what to do.are the diffs on that machine like these plz i need advise are yamaha diffs better then can am. btw i will not be doing mud riding just trial on the xmr outlander.

[@grizzlyman700zr]

Bad drive shaft is the problem.

[@danmoffat956]

I have a 2013 Can Am Commander 1000 xtl !!Did you have an insane grinding noise when in reverse ??

[@mudNwheels]

+Dan Moffat usually ther is a noise in both directions. just make sure it is not your trans. look at all your fluids that will give you a good indication where the trouble is

[@danmoffat956]

Fluids are all good !!Grinds only in reverse

[@markbekkers8364]

which new model can am atvs have the best diffs? other than a 1000. 850 models or under. thanks.

[@mudNwheels]

in 2019 most can am are running the larger xmr diff now. this is a better diff than the one in this vid but still pretty suspect to failure

[@waltertaylor3413]

will your xmr diff hold up to a outlander that has over 95 rwhp that is running a 20 shot of nos? if so who's running these in there machines?

[@mudNwheels]

+Walter Taylor my xmr torque series rear diffs have been i bikes like this. check out extreme atv offroad and his 1020 gade with a 30 shot or rear time atv with a bom racing motor and a 20 shot. o how about dustin jones in the cmr race series. just a hand full of names for you to check out for your self.

i wont have these issues if i order the new resigned full diff from you guys? its for 1st gen outlander 800.

you will have much better luck but dont over look your prop shaft. we have vids on proper phasing also

[@TravisCadello]

@@mudNwheels I also didn’t see a wear ring come out when I pulled it all apart. & yes I was looking on your website but couldn’t find a 1st gen prop shaft. I’d like to change it all & be done with it

how many hours do you have before the first problem

[@skiwee96]

How much do you charge to fix it?

i can do my mod for a couple hundred bucks. most diffs i see need a complete rebuild that can get a bit costly

[@dgreen908]

All be calling you soon

[@olegk455]

People, it’s not the shitty heat treatment that everyone is talking about, or the so called flexing housings, or even the oil itself for the most part. The reason for all the failures is the INCORRECT SHIMMING of the crown gear in the housing. See those two little shims on each side????? Get it apart and re shim it properly then put good quality oil and forget about. That’s the secret!

[@mudNwheels]

you are correct but there is more to it than just the pre load and back lash shims. prelaod of the pinion bearings and pinion depth also play a big role. knowing how all of these settings affect each other is key

[@caseyknox2701]

Folks hating on here because you found a fix to this pain in the ass issue and wont tell them your secret when they should just be happy someone put in the time, work, effort and money to solve it. I dont blame you one damn bit i wouldnt tell either. Make that money .

[@julieandwally]

Interesting, already subbed awhile ago. Let's see the solution?

[@Pyr0Maniac01]

what's the saying? a magician never reveals his secrets?

[@adambarker3578]

The problem is can am should be using helical cut gears not straight cut gears in there diffs. Helical cut gears are quite and have more tooth contact at all times making them a lot stronger. Straight cut gears pull on one tooth at a time causing noise and excessive wear on teeth. It's just a cheap way to build a diff and F the consumer.

[@mudNwheels]

i tend to disagree yes spiral bevel gears are stronger and quite, however i have been building these diffs for more than 2 years now with huge success. my builds reduce the noise and wear and have bee running strong in the toughest conditions that i have tested them in. the xmr 1000 diff uses the spiral bevel gear and they still fail prematurely from stock. i also build these diffs with better than factory results. in fact this on of my strongest sellers.

[@dsmith3239]

Looks like quality control and durability of these diff gears are not a real priority for Can Am. Seen to many of these failures and then being told that it is not covered under warranty as it is suspected abuse. Well, if things were engineered, tested, put together correctly at the factory this stuff should never happen under any type of normal to moderate wear. Come on Can Am, fess up and admit to a total failure here.
