Question on Lockers

I recently bought an 02' TJ and it came with ARB front lockers. Does anyone have any use with this system? If so, what are the positives/negatives? Sounds like a good system, but haven't been able to use on trail yet...

ARB lockers are one of the best if not THE best lockers you can get. They act like an open differential when turned off, making them great for a daily driver. Then with the flick of a switch the compressor will turn on, supplying the locker with enough air pressure to lock it into how a full spool would act. Both tires are forced to move at the same speed, meaning if one wheel is off the ground or has low traction, you can keep going. Know that it may be harder to turn when the front axle is locked because the wheels cannot turn at different speeds like they would like to. Rear lockers don't have this problem as much, but it still can be noticeable. Congrats on the jeep purchase! Welcome!

If you bought a Jeep with ARBs that is great news. I put about $1500 into each axle to get them totally rebuilt with ARB lockers.

I bought a wrangler with front and back lockers but haven't used them yet.
What's the procedure for using them? Like turn on compressor first? and then switch rear on, then switch front on?
I am a bit lost. The guy that I bought it off didn't give me a full explanation.

Thanks

Yep, turn on the compressor to pressurize the system, then flip on the lockers. The pump won't run all the time, only when it needs to in order to keep the pressure up. Be careful if you need to turn a lot with the front locker on, it can be pretty hard to turn with a front locker at times. Just play with them and you will figure out what works best for you.

So I turn on the compressor....how long till I can expect the system to become pressurised? I'm guessing a pretty small time... And then I flip the switch for the lockers....do I have to move the car slightly for them to lock or they will engage straight away? Is there a characteristic sound that they have engaged?

So once it's engaged and I have turned off the compressor it will engage by itself when its needed to keep it engaged?

I only ask cause I was going driving today with a mate and turned them on....or how I thought you would and they didn't engage. Like I am pretty sure I would be able to tell if they actually did engage cause of the steering aspect you talked about.

Thanks for the help.

This is why I love this site. Everybody is helpful to newbies like myself

When you want them on, you just leave the compressor on and the locker switch you want on. It will only take a second to come up to pressure and the compressor will only run if it needs to (if there is a small leak somewhere). You don't have to drive at all to get them engaged. When you want them off again, just flip the switch for whatever axle you want off to the off position. Once you have flipped both axles off, you can shut down the compressor.

You need to keep the compressor on for them to stay engaged. If you turn it off it will release the pressure and disengage them.

There is no sound when they engage. Also depending on your switch set up you may have to engage the rear first before you can engage the front.

Once I hit the trails I typically turn on the compressor and lock the rear. Then I just lock the front when needed. The compressor will kick on every now and then as needed, not that often.

If I'm just running Forest Service Roads or other light duty stuff then I leave it off.

and thanks guys for the help. I think I was going wrong with the compressor. I wasn't leaving the compressor on. I was turning it on, flicking the switch for the lockers and then turning the compressor off cause I thought they were engaged.

I will try out your suggestions. Thanks very much.

I can see why people don't roll with their air lockers on all the time while on the trail....that little compressor can make quite a noise haha

Thanks

Properly wired using ARB's wiring kit, there is no need to have or use a separate on-off switch for the compressor. Using ARB's wiring kit, the compressor automatically turns on & off when needed by simply turning the locker on & off with its push-button locker switch.

I saw on another thread about the type of compressor. Mine is the one with the extra little tank so I can pump up my tyres as well so I have a separate on/off switch. Does this change anything???

Thanks

You'd need a separate on-off switch to air up tires.

But for just operating ARB lockers, a properly designed air system (like ARB provides in a pre-sired kit) would eliminate the need to have to turn the compressor on-off separately from the locker's usual on-off switch.
