I have an ARB in my Work truck. There are 12 other trucks at work that have them too...

I have never heard of that. Are you sure they are not just Eaton Roadranger air actuated locking diffs?

No, I am not sure. But they are Rockwell diffs. Either way, it is the same principal as ARB's. There are several systems on large trucks that are air actuated, and we rarely have problems with leaks or other air system glitches. The most common problem we see with our air systems is moisture in the lines which can block air passages in cold weather. Even my windshield wipers are air actuated.

Our Freightliner has 2 Rockwell drive axles w/ Air Lockers... I dunno if they are ARB's either, but they operate like 'em & sound like 'em.

I've driven it with the lockers engaged... :cool: Actually, we got out truck really stuck once, wheels off the ground and all... :rofl: We turned on the air lockers & stacked rocks just as if we were wheelin'! My boss didn't think it was going to get us unstuck, but he had no idea who he was talking to! :D

That is what I thought. I have actually worked on them and while they are air actuated the principile is kind of different and has as much in common with an ox as an ARB. If you pull an axle shaft you will see two sets of splines, the second set of splines is locked to the diff case by a shift fork. They don't have too many problems because 9 times out of ten a truck driver will destroy the power divider by spinning out first. :D

:rolleyes: Yeah, okay. We use them almost everyday, for the same reasons people use them on the trail, more traction. My point was, they are air actuated, and that seems to be what most people have problems with in their ARB's, the air supply reaching the locker.
