ARB Locker Problem

Was offroading in Coppinger Cove on Monteagle Tn couple of weeks ago, going down the mountain was fine but having to climb back up through wet leaves and boulders put a strain on just locking the center diff so started up the compressor and hit the switch for the rear locker. Noticed compressor would not go off, so got out and looked under truck for break in air line, could not find any air leak but did find air coming out the rear diff vent hose.
Guese an o-ring or seal broke inside the diff caussing all air presuure to come out through vent hose. What is the procedure for fixing? Do you have to remove the third member and tear down diff to fix?
Would I be better off putting a Detiot no-spin locker in the rear and move the ARB to the front?

Thanks for the any help/opinions!

If it was me I would do exactly what you are describing, put the Detroit in the rear and the ARB in the front and I think you would have the best of both worlds.

I have a detroit in the rear of my d2, and down the road, I hope to change it to an ARB... having a selectable locker is definitely better in a lot of situations, especially on rocks and trying to make tight turns.

Haha, it's a never-ending debate! But as someone who does have a detroit, and wheel it a lot, I do find there are times where I do not want to have a locker...

I have a Detroit and it works, this fellow's ARB let him down. If you want a bolt it in and forget it solution that will get you home then the Detroit is the way to go. Sure there are trade offs but I have seen too many ARB's fail to function when they are needed to want to go that route.

I agree, and that is the reason I didn't go with the ARB... more things to fail... compressor, electronics, air lines, etc..

no solution is perfect though, there are tradeoffs in every situation.

Price + Reliability = Detroit

Think about it, you actually NEED a locker about 1% of the time you drive your truck and how many times does the ARB let you down when called on, more times than can be justified by the extra cost. I would probably go to a selectable locker if ARB made an electrically activated locker but they don't and I don't want a Toy conversion so Detroit is it.

To answer you original question, yes, you need to pull the third member. It's not hard at all - pull the axle shafts and drive shaft and unbolt the third member. I bet one or both of the o-rings on the seal housing failed. It's a simple and cheap repair you can do yourself. I doubt the locker itself failed.

On the other hand the Detroit in the rear of a short light vehicle can be entertaining.
How many 90 owners have detroits in the rear of their trucks?
I love them but there in the rear of heavy Disco's and a 110.
The one in my Jeep was brutal.

Just wondering what you found to be so brutal about a Detroit in a short wheelbase vehicle? I've got the classic Detroit rear, TT front setup on my 90. It's been fantastic with no trouble at all (okay there is that occasional "CLUNK!!" where everyone looks to see what broke and/or fell off of your rig in some tight turns)

It could have been the loose suspension or maybe the 400 horsy's under the hood. I loved it though, never a worry. If it unlocked on the highway it was "exciting"

I have heard from a number of customers that they don't like their detroits in the rear of the 90's. That's only a smattering of users though. More opinions help form better decisions.

The detroit is by for the best bang for the buck when it comes to lockers, I'm a big fan of Detroit rear and selectable front.

Perhaps its all about what you can get used to.

I have had 2 trucks with dual ARBs and never had them fail My new Toy setup will have ARBs I set them up with pneumatic switchs to get rid of all the possible electrial problems and a barrel regulator to decrease the chances of blowing the seal with too much pressure.

I have seen some interesting off camber attempts with Detroits and snow and ice ... I agree that a locker is ony of use 1% of the time and because I do a few trials events the Detroit would be a huge hindrence but everyone has there own wheeling style so each should pick his poision

Try cleaning out the breather tube to the axel... Mine was packed with mud and it was pushing gear dope into the solenoid.

Air from the compressor was coming out the breather tube for the diff. Would a blocked breather tube for the axle cause this?was in mud and swollen streams most of the day so a blocked tube is not out of the question.

I think you will like the ARB much better than the Detroit if you ever drive icy roads. Even more the shorter the vehicle is.

The ARB is much faster to engage and disengage than the elockers that I have used.

Also, I can't speak for all brands, but the E-lockers have their fair share of problems as well. I know we have replaced quite a few LR3 E-locker rear diffs under warranty.

I would bet money it's not your O-rings, but the "U-ring" instead. Dig up your old install paperwork and check the exploded diagram for the location of this part. You will need to take out the carrier and open it up to perform the repair. It's and easy job though. Talk to the tech support folks at ARB to get the correct parts.
