This is a dumb question, but as I just "don't know", I figured I'd ask it here. Had an '86 Chevy C10 2WD with a 3.08 LSD/Posi/Whatever. Just after we bought the truck, I drove it over to my parent's house that had a fairly steep paved driveway, with Iceplant on the side. People were forever and always getting stuck in the Iceplant - VERY slick. So to test my fancy new truck, I purposely drove one side into the Iceplant on my way up the hill. As expected, that wheel started to spin, so I backed out of the throttle. As I did so, there was a VERY "hollow sounding" clunk and the rear of the truck kind of twitched. I then gave it throttle and the the other wheel that was still on the pavement pulled it on up the hill.
Was this the "normal" clutch pack type LSD, or something else? What was going on?
The only other experience I had with it was a couple of years later was learning that "positraction" can mean you have to dig out two wheels instead of just one! Both rear wheels dug in on a sandy-soiled hill until the pumpkin stopped further downward travel of the axle! No clunking that time - they just both quietly dug in! Shovels are good things...
