Can't say how much Sweetness and I enjoyed the Unofficial Fall crawl at Superlift... Totally great group of guys. Very impressed how the low riding Green Jeep worked on the rocks and climbs. I thought lowering would have killed it, but it did great. In the end, my heavy foot killed it... Broke down on a level 5 trail, "Greg's Rock". Luckily limped out in front wheel drive. I broke something in the rear end and neither tire is spinning. So, help me trouble shoot this, I'm brain dead from the weekend and haven't pulled it apart yet. The drive shaft is spinning but nothing is going to the tires. I pulled the cover, ring gear looks good, and no loose metal in the oil. I threw it in neutral and turned the driveshaft, clean spin with no noise. The ring gear is turning and the wheels are just sitting there.
So what you guys think, is the ARB locker broke or did I snap both alloy shafts? Or something else... I am about brain dead, so it could be something simple.![](http://i27.photobucket.com/albums/c156/zboss86/null_zpsd409fa81.jpg) Details... Dana 44, ARB locker, Alloy shafts

Does it make any noise while turning?? Not fluent with the ARB's but if it was an open diff and the spider gears, and R&P looked fine I would have to say both shafts.. Quick way to find out.. take both side shafts out and look.. 4 nuts on the flange and it'll slide out..

Shad, the rear passenger tire was spinning on the trail before you winched out.

My vote is axles. It is extremely rare to break an ARB. Not to say you can't but typically those are bullet proof.

Shad, the rear passenger tire was spinning on the trail before you winched out. From what I understand if the ARB breaks it turns into an open diff where at least one side will spin.. Jack up the rear and have someone hold one side while you try and spin the other side.. see what happens..

I'm going with the ARB. While you can break both shafts...I'd say that is very rare.

We're at a dead heat with 2 votes on each item. Apparently, I didn't provide near enough info. My question, I've never dealt with a D44. I suppose it doesn't have C-clips like the factory D35 or 8.8 rear end. If it does, I sure as hell don't know how to get to them. So I'm guessing it has 4 flange bolts like a 9" or c-clip eliminators that hold the axle in place. I jacked the rear end up to spin each tire. No need for a second person to hold the other tire. It sits still while the other spins freely and quietly...

She ain't now... With the ARB, the axle is open until engaged. I would assume that if it broke, it would go back to open. While it's probably rare, I'm guessing its both axles. Maybe I'm just hoping its the axles and not the locker. Hell, I'm kinda excited about pulling it apart, my curiosity is getting to me.

In the first video you can see the inside of the locker spin... so Now I'm gonna say either the driver side axle shaft is broke or the locker is toast..
Either way you'll have to pull the axles to get the carrier out anyway..
And yes the 44 has the nuts on the outer flange like a 9" with no c clip.. Just take the drum off and you'll see the nuts. Use the hole at the axle end to get a socket thru... If you broke an alxe shaft the flange will more than likely be bent out in the middle due to the outward pressure caused from the break..

Yeah, I'll yank them today. I just didn't want to wake the neighbors last night with the impact. I got disc brakes in the rear. I'm wondering if the the flange on the inside of the caliper bracket or outside. Guess I'll know when I pull the wheel. The one time I prefer drum brakes is when pulling axles... Nahhh, I'd still would rather have disc, I hate to even look at drums.

If it is the locker, I know that Yukon has an awesome warranty and I believe they designed their air locker to stay locked if you lose air pressure. Basically reverse engineered from the ARB that requires air to lock it. Only downside on a street rig is that it requires air to stay open.

I wanted to vote but I couldn't find the 'I have no clue..." button. Wish I new more about the internals of the differential...dig into a motor, no prob (heck, I've even pieced together a few manual trans in my younger days), but auto trans and diffs are black boxes for me. I understand the theory/principles, but no actual hands on...gonna have to learn though so I'll keep watching this thread.

Have you tried engaging the locker and then try to spin the axles?

Have you tried engaging the locker and then try to spin the axles? No, I was too brain dead to think about that. But it did cross my mind at work. That maybe the reason I had the passenger wheel still turning on the trail. I'll do it for shits and giggles before I yank the shafts.

It made a hell of a noise when it let go, whatever it was...I was standing right beside it when it happened.
And yes, the passenger side was still spining.
