Rear end???

I'm trying to figure out if something is wrong with my rear end or if it's a different type. I am totally ignorant of what or how it works but if I get stuck in mud or on ice only one tire spins and the other does not engage. If I launch really hard and it breaks traction or if I burn out it's always only one tire, it gets annoying lol. I have a 2001 2500 with a 6.0 that does not do the same thing, it seems like it is always locked in. I have been told that it is a posi ( not sure if that's true or not). I would just like for both tires to spin when I need them to. Any help or suggestions would be a great help and sorry if this is a dumb post

The G80 locker isn't impressive and it sounds like it broke.

I'd look for alternative aftermarket rebuild options though.

What would guys recommend as a good option? And who makes them?

Thanks, who carries them? Is there some way to make the rear lock in so I can make sure it is broken or is it pretty much gone? Thanks
