Open diff acting like an LSD. What the fudge?
Alright so to give some background I do drive my truck quite hard some days, maybe more than I should but this has me wondering if I broke it or I'm just having bad luck. To give some background I was going around an intersection that is normally very empty in terms of traffic (Middle of nowhere with nobody around for miles so nobody to annoy) and was wanting to do the normal one wheel peel as I went around the turn. Weeeeeeell instead of spinning one wheel she was spinning both, now I'm all fine and dandy with that fact except because of the way it shifted around on me i about nailed a guard rail so it leaves me a need to investigate why my rear end is acting in this way. I have yet to check the fluid level but I will do so later this evening but I want some opionons from the rear end guys, mainly so it doesn't become the death of me the next time I wanna be a little wild.
Now I do realize some of you folks will call me an idiot for doing such a thing but let me assure you I only do this stuff in areas where nobody is around to be bothered and as safely as a possible, hence why I'm posting up so I know I'm not about to hurt myself or someone else. Because lets be real here if its gonna slide I'd like to at least know that I'm wanting to and not just when the rear end wants to.

Yeah that's normal. With an open diff, the tire that is NOT spinning only receives as much torque as the one that already has no traction. Normally this keeps it stuck to the road while the other one roasts away in a one tire fire. If you happen to go across some gravel or something, that one tire that wasn't spinning can now break loose and now you're sliding sideways. Great fun if you do it somewhere safe (sand, mud, gravel, open field, watch for ruts!) but not so fun when you look over and see a guardrail.
I have done this without trying in an 302 auto Thunderbird. Just making a left onto a divided highway, normal turning speed, road's a bit slick (had been raining nonstop for days) and the @ss end came loose. I let off what little throttle I was using to wait for traction to return but it never came til the poor car was almost 90 degrees sideways to the road. By then it was too late to power-slide the rear back around, I actually had to stop and back away from the median. I'm sure everyone in the two gas stations there pumping gas got a good laugh... I looked like an idiot and I would definitely laugh at someone if they did that in front of me.
