Stock, you can lock the rear, and not the front:

This is from my `04 manual, s/b the same in `05
The Axle Locker switch is located on the lower center of the instrument panel. This feature will only activate when the following conditions are met:
• Key in ignition, vehicle in 4L (Low) range.
• The vehicle must be traveling at 10 mph (16 km/h) or
less.
To activate the system, press the switch once to lock the rear axle only (the REAR LOCK indicator light will illuminate), press the switch again to lock the front axle (the FRONT LOCK indicator light will illuminate). Once the rear axle is locked, pressing the switch again will lock or unlock the front axle.
NOTE: The indicator lights will flash until the axles are fully locked or unlocked. A chime will sound three times and the indicator lights will continue to flash at a different rate if the key is removed while the axles are still in the locked position.
To unlock the axles, pull up on the switch.

The only way to lock the front separately is to add a switch that controls the front. Search around and you will find threads were others have rewired their Rubicon lockers with individual front and rear switches. If you know basic electrical, it doesn't look too difficult.

Also, look up the rubicon locker switch mod. It isn't what you are asking for, but it does give you more flexibility for locking options. It's a 5cent upgrade that allows you to lock in any t-case position. I have made use of it often enough.

The Superchip has no affect on the lockers. I might suggest researching that as well. Many will argue that isn't doing a thing to help your engine.

I installed locker over rides in mine. With these I have true independent control and they work any time, any gear, any range, any speed.

Not a problem in the world. All it is are two switches and two ground wires.

2003 rubicon air lockers will not engage

Scroll down to post#14 for the diagrams.

That looks familiar!

Jeepit, this is what I described earlier. While it does not allow you to engage the front lockers separately from the rear, you will be able to do everything else. Being able to lock while in 4H is the practical reason to do this. You can even do silly things like lock both ends while in 2H (don't do this). I would suggest jumping wires 1 & 4 which still enables the 10mph speed restriction.

You can do this with a paperclip if you wanted to.

Other than locking in 2H (not sure I'd need that ), what do they do that can't be done with the stock switch?

The stock switch only allows you to lock while in 4L and while under 10mph. Modifying the switch allows you to lock in any t-case position. You also have the ability to over-ride the 10mph limitation, though I would not recommend going this extra step.

Don't over think it. I modified my switch within the first week after I bought the Jeep. It took about 15 minutes and an inch of wire bent into a U-shape that is shoved into the back of the plug. Most of the time is spent taking the dash apart and re-assembling.

CJChet has gone a step further and has bypassed the stock switch entirely. This allows him to independently lock the front and bypass the speed limitations. If I were to guess, i would say his stock switch, if anything, is now just an on/off switch for the 2 switches he added.

The speed override can be very handy. We had some snowy/icy/muddy conditions up here a few weeks ago and the club attempted this huge hill. Only way up it was fully locked in 4Hi with decent speed. Otherwise you were playing the winching game. (It was so slick that if I stopped on the hill, I would gain speed sliding back down the hill with all 4 tires locked up)

Here is a better writeup. It allows TRUE INDEPENDENT control of the lockers. Yes that means I can lock my front only, and I can also lock my rear in 2 HI! I do it all the time and it works like a champ. Its also very easy to do. I can lock any axle, any time, any speed, in any gear, in any range. Obviously, some caution has to be exercised here, that's why I used the "missile" switches".

How fast did you need to go? If I recall correctly, the Rubicon lockers automatically disengage at 40mph. I found this out several weeks ago on a snowy, gravel road and had to do a full shutdown to re-engage.
