I've got what GMC refered to as a locking rear in my 2001 Sierra 2WD. I had expected a switch to lock it but I have nothing still I know it locks. I've tried but have never been able to find any information on how it works. It definitely behaves like it's locked not limited slip. Take for instance the day I backed off a paved drive into a rough area to have mulch loaded. I hit a slick spot and one wheel spun for a second then I get that clunk and back it goes. I got loaded and pulled forward unto the pavement turned hard to leave and it was actually slidding the front wheels a bit as they tried to turn the truck. It did turn but it was a fight. The inner back wheel scuffed and scraped the whole time. And I was just crawling. That's the way this rear works. It requires a spin of a certain speed or time and I hear a clunk and either it moves out or both start spinning. Once locked it remains locked until it is driven straight for a bit. Another time it locked backing onto a paved parking space off of grass at work. Later that day I went to leave not having to get on the grass again but as I turned out of the space it was locked. Being unloaded this time the rear didn't put up much of a fight--just a hint of push and the inner rear chirped away. I remember asking someone at the dealership about how it worked and he said like the old posi-traction rears, but personally I don't think so as I think they were limited slip.
Anyone here know what's in there and how it goes about locking it up?
