I get the joke but you really need to know much more than that unless you want to F up your new ride yo.

Just out of curiosity, do you have one button for each locker (front/rear) or one button for both?
Does the rear locker need to be engaged in order to engage the front locker or can you engage the front independently?

Jokes aside, it's actually one of my concerns. I've never had a locker so don't really know when to use them. Specially when to use the front vs rear vs both.

The Rubi has one button that controls both lockers - according to the manual:
- pressing once, switches on the rear locker
- pressing again, switches on the front locker also
- Unlocking follows the same process, press once - front's unlocked. Press again, rear unlocked.

I'd see people pose this question on the Jeep forums and you always get 10 different answers from 10 different people. Some say only once you get stuck and others will argue that they always have the rear locked once they leave pavement.

As for me personally I try to use them as little as possible. I'll give the obstacle a shot open 2 or 3 times, lock the rear and try another 2 or 3 times, then finally lock the front also and try 2 or 3 times. If I still can't get over I reassess and either take the bypass or break out the winch.

As you get used to the affect your traction and etc you'll know when to turn them on beforehand and they make a world of difference.

Locking the front makes steering a major PITA though so keep that in mind. I know some Jeep owners opt to install hydro assist just to help them steer with the front locked.

Check out these vids of Pizza Rock in Rausch Creek. We take the same line one had lockers the other was open. Though the higher lift and bigger tires on the 2nd vid don't hurt either. :D

Just watched this video. Thanks for posting. I'm mechanically inept and this really helped a lot to learn about my machine

Great videos! Your buddy “JB” must hate those one after the other like that.

When I first put in my rear locker I had that crap on all the time. I did not realize how much trouble I could get into. Now I’m like “Brunk” and try to use them as little as possible.

The locker(s) can cause my truck to “crab” sideways, down slope, in any type of slick off-camber situation because both wheels are rotating at the same speed causing them to fight each other, breaking traction in any situation but a straight line. When my diff is open (locker disengaged) the static wheel won’t fight, anchoring the truck and help it not to slide. The front locker will cause the front of my truck to “crab” even more because it is also fighting any steering input other than straight ahead. I now let my junk just idle through those situations, open, in 4LO, giving it the best chance to maintain traction.

If I use the rear locker to help get up an incline it has to be straight up otherwise I’m off-camber and the rules above are in effect. If it’s a rocky incline or one with a ledge or two I wait until I’m stuck to turn the rear or both lockers on to help.

In deep mud like at Robby’s the lockers make my truck go straight even if I’m trying to turn so I stay open unless I get stuck or its wide open and I want to throw a lot of mud at the bystanders. If I do need to turn the truck in this situation and don’t want to unlock I can slow down or coast, turn and then hit the gas; it will pull in that direction for a little bit before pushing the truck straight.

Sometimes you can use your locker to “crab” around an obstacle, tapping the throttle to purposely get the tires to break-away…fun when you plan and then do…

One of the only times I’ll lock before I’m stuck would be going straight down a steep decline. It is a blast all locked up in 4Lo (crawler gears); engine breaking, all four wheels with traction, no foot or hand brake…wheee.

I have never run my front more than a few seconds and have never forgot to turn it off because I can feel it fighting the steering. I have forgotten to shut off the rear many times and have had near disasters twice because of it.

Once at ECXC and another at the 2012 Northern Exposure Run;

Yikes!

As long as I’m not spinning my tires I can turn on and off my ARB rear locker whether I’m moving or not. I have my front ARB wired so that I can only turn it on when the rear is on (as ARB suggests) but can also do this whether I’m moving or not.

Lockers cause wear on any truck and I do not feel the front axles, IFS and steering in my Xterra are strong enough to handle being locked up by itself or for any length of time (one of my concerns with the Lokka). The front axles in my truck cannot push or pull the full weight of my truck. :cry:
