How is this beating a dead horse? Please if you dont have any usefull information to contribute to my thread then dont bother posting.

This is a difficult decission for me, I have the cash to buy everything but want to make sure I have heard both sides so I can make an informed decission on which to buy. I still am not totally convinced but am probably leaning towards the OX for its simplicity. I just wish more people who had them would post....or maybe their just isnt really that many people that have them.

What does an 'x-ring' look like? First I've heard of such an animal...at least by that name...

*Just picked up a D30 and D44 this afternoon, packed with goodies including OXs.... Guess I won't get to use the Ruff Stuff covers....:(

Cut an o ring in half and look at its cross section, looks like the shape of an O. Correct.
Well, do the same to an x ring. it looks like the shape of an
X.
You now have multiple planes to seal with an X shape, as opposed to the O shape.

Hope this makes sense.
 
I'm running Ox lockers front and rear. D30 D44 No problems. Took a couple times to adjust the pull at first installation. But after that all good. Runing them four about two years so far.
 
3 ARB's going on 8yrs and no problems.They have been severely abused!!

but somethings is leaking and i cant find it which makes my compressor short cycle. So i believe its inside and there is really nothing i can do.

Yeah there is: Take it apart and FIX it.
10 bolts on the diff cover, Inspect the copper line and find the hole. If no hole, pull the 4 bolts on the carrier end caps, pull the carrier, pull the passenger side air input to the arb. Blow out the air hole in the carrier with compressed air, change the o rings and reinstall. 2 hours if your slow, and it's fixed.

Or just soap test the air lines from the compressor tank to the ARB and find the leak and tighten. The leak may not be in the ARB at all.
 
I love the fact that if you upgrade to the bigger compressor with an ARB you can air your tires back up at the end of the day!
 
Ive been running an ARB in the front for a few years now and have had my fair share of problems. Even with the issues I wouldnt run an OX, or any other locker in the front. Most of my issues were install related, since I have fixed those problems it has been great. I have mine powered from my AC compressor OBA and before that a CO2 tank

regarding the OX locker a good friend of mine has one and it just failed the other week. He hasnt pulled it apart but it sounds like the selector lever(or whatever its called) bound up and either bent or broke. Could also be in install issue but with the cable stretching makes it hard to dial in and leave it alone.

Hope that was any help and no bad info on the OX problem.
 
Only had my ARBs for a short while but I really like them. One of the advantages is that you get an air compressor on board to do other things like inflat tires, run air tools, etc. Can't inflat tires with a OX.
Installation is key, I know someone who zip tied his air line to his exhaust, that doesn't work. Have fun!
 
well i have a ox front 2 of my other buddies have them and they have been trouble free, u must install it correctly like anything eles but i feel there more simplistic. they always work and if ur cable does strech its real easy to adjust with just a screw driver. i have seen many rigs with air locker not working cause all types of things heck one day i was with 4 rigs that had arbs front and rear and non of them worked but thats my 2 cents
 
I said some of this in my last PM to you on the other forum, but I figured I'd throw my $.02 in here since I've got direct experience with both lockers.

OX vs ARB is a tough one... we like both and have been pretty happy with all of them. Personally I think I kinda lean towards the OX though, mainly because it's all mechanical -- you never have to worry about air leaks, or electrical issues, or anything like that. Not that our ARBs have given us any of those troubles though, but with an OX they aren't even a possibility.

The biggest downside to the OX is routing the cable and mounting the shifter -- this is probably the biggest issue for an XJ installation. That's where the ARB is nice because you only have to worry about mounting a rocker switch. The OX also comes with a bomb-proof diff cover which helps sway the cost benefits more towards the OX again.

Between our 2 Jeeps we've got 2 ARBs, 1 OX, and 1 Detroit. We got the OX (D30 in the front of our TJ) back right after their first came out. I think we got it the summer of 2001. The only real problems we've had with it were related to 1st generation design bugs which OX subsequently resolved. Aside from the cover all our OX components (shifter, cable, carrier) have been replaced/upgraded with their current generation of parts.

I've had the ARB in the front of my XJ since the fall of 2002, and it was used when I got it. Other than a pesky leak around the threads of one of the fittings on the compressor when I first installed it, my ARB has been absolutely trouble-free.

The only trouble we've had from the ARB in the rear of our TJ had to do with oil drainage from the driver-side tube back intot he diff. Despite drilling 2 drain holes into the tube from inside the diff oil would still build up enough on that side to start spewing out the breather tube. This was on the road, with the compressor off and depressurized (it never spewed off-road). I think some of that probably had to do with excess heat during the gear break-in period (I installed the ARB at the same time that I regeared our TJ to 4.88s).

As others have already stated, the biggest cause of problems with either locker is improper installation.
 
can you not install an Ox in a D30 if you have 3.55 gears? It is my understanding that only 3.73 and up (4.10? etc) will work on the D30 depending on spline count. Why not make one that works with 3.55s?
 
I think the bottom line is that you should just go with what you want/can afford. There will be an unending list of pro's and con's for both just as there is always going to be horror stories about both. I personally like the OX because it is a simpler design and it come with a robust diff cover, but that's just me. They are both excellent pieces of equpiment and they both have their flaws.
 
Been running OX front and rear for over a year now with zero issues. I think the main problem people have with the OX is the initial shifter/cable adjustment. Do that right and you'll have no worries. Super heavy duty forged diff cover is a major plus.

why would you do that kind of locker and still be running stock gearing?

Because I have an np242 and love my full time feature on the street if it calls for it. Selectable lockers would be to my benefit regardless because not all conditions call for a front locker anyway.

Regardless an OX WOULD work in my D30 if I had swapped in a 4.10 R&P correct?

Yes any ratio 3.73 and numerically higher, up to 4.88.
