Well maybe not THAT bad. But I'm not happy. Broke a left side output shaft last night. Climbing a steep 100ft or so rocky mountain and half way up.....clunk and sharp left turn. Got home fortunately. Thought it was a CV joint again. I just replaced the left joints and axle in June. After inspection it was the output shaft. Don't know where to go from here. Doing some searching on the net I found out that latter in '08 the Sand Vipers came stock with open diffs. Mine is an '07 closed, or locked diff. Maybe I should look for an open diff as a replacement. Any suggestions? Thanks in advance.

left out put shaft on a viper, would that be the same as the rear output shaft on a trooper, the output is not that hard to replace, just time consuming and you have to pull the engine. I may be wrong, you may have an actual differential in there, but I'll bet that other than that, they're the same.

went looking at the part list for a 2008 viper, http://www.jmcmotors.us/manuals/1100sandviper_parts_manual2008.pdf , and it does look like what I had to replace.

I beleive your talking the rear left axel. If its the same axel as the Trooper uses, I have some for sale. I dont think the locked diff has anything to do with it. If your engine is turned 90 degrees to how the Trooper engine sets, then Kinarfi may be right.

Here is a link about the two diffs.

Here is a link about someone else having the same break.

One of my friends said to pull the oil seal and try to get a hold of the shaft and pull it out. Then replace the shaft and seal. That shaft is probably locked in pretty tight.

Off the subject, hi jack, but I wonder how that differential would work in a Trooper, you would have to put it 4 X 4 and leave it, and I guess that if any tire got off the ground, that would be the only tire to spin. Bad idea I guess. Unless you can find a lockright to put in, actually I'd want 3 of them.

I'm not sure. I think you have locked differentials like what I have now but you have the levers to lock and unlock them. I've been talking to Kinarfi and when I get my parts I am going to send him pictures. He can explain things a lot better than I can.

Oh so you was looking to use locker in sand viper using trooper's locker?

The Trooper and Viper have the same Motor and Trans...Yes...BUT The Trooper uses a SOLID OUTPUT shaft, it drives both front and rear drive shafts while the Differentials do the locking and unlocking. The OLD Viper used to have a SOLID OUTPUT Shaft, but now has an OPEN OUTPUT shaft, and YES they are interchangeable. The seperation comes where the operation happens....the Viper Trans drives the Axles directly....the Trooper Trans drives the Differentials which drive the Axles....I hope this makes sense....lol

Yes it do...so best fix for Bruce would be the later open one?

Any idea why change from locked to open on those?

Yes...however, we are out of stock at the moment.

The reason was simply due to the Failure Rate and the fact that the Viper PUSHED thru corners real BAD. Not to mention customer complaints about it being hard to push around.

A little clarification about diffs

Vipers and Trooper have the same motor and transmission ---- I think

This is exactly right. Mine is an '07 Viper with a closed diff and in late '08 they changed it to an open diff. I am going to replace mine with an open diff. See Kinarfi's diagram.

This is true and why I am changing to an open diff.

I just got an crazy idea lol but i was wondering if i could get that piece that's between the front differential and front driveshaft that makes the trooper 2wd and put it on rear differential..maybe whole another front differential case if it have special boss for that piece but anyways i want to know if i can use that piece to make rear disconnect so i can have only front drive like dig unit on atlas transfer case and such as?

Those are found in crawler and all kind of trail trucks

**DISCLAIMER**

Joyner USA does not recommend changeing your vehicle from its original manufactured state.

That being said....

In theory yes....use a Front Diff flipped upside down in the rear....Drill a NEW drain plug...clock the cover 90 degrees to get the vent tube on top....shorten the rear drive shaft....and run another cable to operate the rear engagement.

ALSO...this will add a lot more stress to the FRONT drive shaft in those cases when only using front wheel drive so beefing up the U-Joints might also be in order....
