2013 Rear Diff explosion(s) Why..?

Ok, This is getting a little odd. My 2103 exploded the rear diff at 470 miles... then the 2nd one at 700 miles... and now the 3rd one at 960 miles.

Since I have other Rzrs, And the rear ends have let go on two different drivers, I think we can safely rule out driver error.

Believe it or not, Warranty stepped up in both the first replacements. I am waiting to hear about the 3rd time.

Tires are 26" Cerros, and I removed the braking clutch before the 3rd diff went in.

We do not moto cross, mud sling, or rock crawl... some tight trails, but mostly just going fast on fire roads.

I keep taking it to the dealer and thus far they have just replaced the broken parts. No one has looked for anything that could be causing this problem.

So, my question is... what could be out of alignment ? OR, can alignment be an issue at all ? The last time I was told something "may be out of align in the transmission"... so they replaced BOTH. It only lasted 260 miles.

What else could be causing stress on the rear end ??

What is it doing? Splitting the stock case at the pinion?

Got pics?

Yep. Then it locks down tight in the rear end. Front wheels won't move it at all.

All 3 times it has been making a clicking noise in the rear end while in reverse.
I usually hear it when backing it off the trailer. I have called the dealer before it exploded
All 3 times.. even took it by there one time and showed him the noise. All three times
He has said it has to be the axle making the noise.

I really think it is just my buggy. That is why I posted on here... hoping someone with
More knowledge than I ciuld help lead me in the right direction.

I know plenty of people who havent had this problem too.

And, I just traded a 2011 in that was going great with over 5000 miles on it.

Re: 2013 Rear Diff explosion(s) Why..?

Yep, same thing here (2012 rzr S) but 1600 miles so I got some more miles out of it. All fluids changed before rec's. Fire roads and mountain trails, never abused at all. We carry a lot of weight on steep mountain trails though so we thought that was why it happened. Locked up the rear end and split the rear diff case and leaked gear oil on the ground. Thankfully, warranty covered it as well.

Same clicking noise, but not in reverse, it was at moderate speeds on flat ground from 10-25 mph. After reading the forums I just thought is was the brake pads, but now, I don't think it was........if you have a clicking noise, check your rear diff main bearing(if you don't have a warranty). If you do, ride with a buddy who can give you a ride out when it breaks like I had to do!

Re: 2013 Rear Diff explosion(s) Why..?

It sounds like the dealer has not got to the root of the problem and continues to just fix the broken parts.

That's what we are hoping to find out this time.

I actually hate hearing other people are having the same issue. I have spoken
to several other owners who havent had any rear diff issues...And all have a lot more miles than mine.

I was even considering just trading this one for another 2013 570 because I have a buddy
who put 2800 miles of hard driving on his 2012 with out one issue.

Our 570 only has a few miles thus far so I am hoping this is not an ongoing
Problem for the 2012 and up models.

Re: 2013 Rear Diff explosion(s) Why..?

Curious what the build dates are on the failed units.......Mine says SCHAFER 3-26-13. Also has a serial #. I hate worrying about a differential blowing up.
