I'm gonna say it one more time...

If your rear wheels spin in opposite directions with the rear wheels jacked up, and it in park, IT IS NOT LOCKED.

If they will NOT spin at all with it in park, it is locked, and if they spin the same direction when in neutral, it is locked.

If you locker pump runs all the time, the diaphragm has a tear, or some other problem, and it's not going to mysteriously lock somehow, and become stuck.


I honestly think you're chasing the wrong thing. I bet you've got a transfer case stuck in 4hi.

It's a BUNCH eaiser to pull those hub slugs up front, and see if the binding goes away than it is to pull that rear differential.
