Rear Diff. blowup

Recommended Posts

Not 100% clear on this yet but a friend of mine who also owns a T2 had his rear end go out on him the other day. He tore it down and found what looked like one of the bolts that hold the ring gear on had backed out and caused the pinion and ring gear to lock up and striped some of teeth off. He is still in the evaluation process and is in touch with Joyner. I will update as soon as I learn more. :(

If you need help, let me know.

I think differential info will become important and interesting.

Just had mine apart to look at it when i was redoing the back. Noticed that all the bolts on mine where saftey wired.

He said that also so thats why im not 100% sure as to what happened. I will see him at work tonight an hope I can get a little better understanding. I am on graveyards so it takes my brain a little longer to compute things :blink:

New update on rear diff. My friend said that the bolt holding on the ring gear did not back out but actualy busted off in the middle of the bolt and the threaded end went out the back side. The bolt head with retaining wire was still in the ring gear. He has some pictures and as soon as I get them I will download onto the trooperfolk webshots. He said that Joyner is working with him on the investigation to see who is going to replace the diff.

Sounds like a defective bolt or the bolt was over-torqued. Great to hear there was not any problems with the safety wire, silver lining!

How long has he had his T2? Is it still under warranty

We both took delivery of our T2's last spring. So no, the warrant was up a long time ago. It was determined that the bolt had to be faulty and Joyner was great about making it right.

exile, welcome to UTV Boards & sorry to hear that. I found this for you from Jeff at No Limits Powersports. It's the factory replacement but it has been checked for proper spacing & gear load. Price $925. You might get it cheaper from Joyner but at least you know this has had the once over inside. http://www.shop.nolimitspowersports.com/pr...p;productId=144

Cheers Mike.

My rear dif has had a clunking noise and my locker wasn't working. Finally get around to tearing it down and all the bolts holding on the ring gear are pulling out. The ring gear would rock back and forth. All the bolts had safety wire or I am sure one would have fallen out and caused big trouble.

All the bolts are soft I will be replacing them with harder ones on Monday and lock tight instead of safety wire. Has anyone else run into this problem?

I think this is a known problem by Joyner. My dealer called me up out of the blue one day and wanted to know my diffs serial number. He has seen this same thing twice and is trying to be proactive about the problem. This may or may not help but I'd give Joyner a ring and see what they can do for you.

The whole axle comes off of the rear end. The rear dif has stub shafts that the axle slips on to I just took a long pry bar and they popped right off.

Sound Like I have the same problem, all the bolts are sheared, the safety wire is strewn through out the diff and the inside is broken.

If I don't get one via warranty, any one know of any others, or have any ideas that might help?

Don't think I'll be going anywhere for some time.$$$$$$ :blink::(

The same thing happened to me but I heard the slop in the ring gear and no harm was done. I have also called Joyner and am waiting for a reply.

When did you have your problem, or you having it right now? Where you buy yours?

I heard it for the first time last fall but I did not ride but about 10 miles all winter. I tore it down about a month ago and found most of the bolts had pulled the threads off of them. I put in harder bolts with lock tight and hopefully it will not happen again.

Me too, but if it does, I hope they do as well with this issue as they did with the U-Joint problem. If they do have a problem, it would be sweet to let those who have the problem diffs know about it so the bolts can be replaced or what ever need doing can be done.

Sent email to Casey yesterday and got a call this morning, gave me pretty good deal on a new Diff, Thanks Casey. I'm kind of over a barrel of buy or don't ride, I bought it and it's on it's way :D , along with an unbroken fender, :( unlike mine. After it gets here, I plan to pull the front and check it out, especially if I drain it and the oil is silvery. I recommend the same for any diffs that make any noise, mine did when backing up, or if the oil is silvery.

I'm trying to find some super tough bolts, according to Casey they're jet bolts, M8 with 10mm head, probably a fine thread, titanium or something really tough. If you know where to find them, please post.

My Thanks to Casey, who seems to be trying to take good care of us and still take care of Team Joyner.
