Question about warn hubs and Aussie locker

I was in Harlan a while back and I was going up Pinball when I heard a loud "pop" and the front passenger tire stopped spinning. I replaced the passenger hub with a drive slug and wheeled the rest of the weekend and didn't seem to have any problems.

Today I took out the drive slug and replaced it with a new Warn Premium, I also replaced the driver side with a new Warn Premium hub.

The instructions with the hubs say to lock both hubs, jack up one side of the axle, turn the tire and see if the drive shaft turns. Here is my question... There is a popping sound when I turn the tire and the tires does not move very easily. Is this just the Aussie locker doing what it is supposed to do, or is the aussie's pins Brocken, or is there something else it could be?
 
Is the transfer case engaged? If so it's probably just the locker ratcheting because of to enough torque applied. If not it's certainly possible the pins are sheared.
 
Ahhh, didn't know that, thanks!

If the pins were broken it would act like a spool.

I'm no expert, but it seems to me that if the pins are broken the inner pieces can separate from the drive, outer, gear and it would not act like a spool. The inner parts would be able to disengage from the part splined to the axle shaft. The springs and pins are what makes it lock.
 
Yeah, it wouldn't necessarily become a spool. I can say that if you snapped a shaft or hub while getting on it, lunchbox lockers don't usually fair well. Why not pull the diff cover and look? And throw the warn hubs away for some stock spicer hubs.
 
Conclusion is, I think the locker is fine. I jacked up the front end this evening, locked both hubs and spun one tire, the other turned in the same direction. Then if you change directions, I could hear the Aussie unlock and then start ratcheting. Thanks for all the opinions.

It's in the way the drivers are camed where the cross shaft goes through. The springs and pins align the two drivers to keep the relief or cam where the cross shaft goes through perfectly in line with each other. Yes they also keep the whole works centered with the side drivers too, but it's the torque transferred through the cross shaft that actually "locks" the drivers together. If you look at the relief where the cross shaft goes through, you'll see that it's not perfectly round, but is a cam. The more torque applied by the cross shaft, the tighter the engagement of the teeth. Now, snap those pins or lose springs, and the drivers will go out of alignment with each other, but will still be acted upon by the cross shaft. It'll turn into a ball of misaligned shit. In theory, it will be spooled until everything falls apart.:lol:

I know, my explanation of the failure part sucks, but the pins actually do no part of the locking. They just align the drivers.
