After lots of searching and reading. It sounds like the Detroit TrueTrac is the better limited slip to drop in. The factory limited (or unlimited) slip has been replaced at least once and it still never performs as it should.
The most frustrating thing is make a right hand turn and trying to accelerate into traffic. One wheel peel-outs are not cool. I've lost a lot of tire life and it's not safe when the power isn't getting to both tires. I usually let off the throttle to stop the wheel spin, but then the tranny upshifts and starts lugging the engine.
I've added friction modifier, but I think the clutches are shot. It's open.
It's too bad I didn't do this when I bought the truck 8 1/2 years ago.
Anyway, along with the carrier, I'd replace the bearings, fresh gear oil and upgrade to the '08 cover (with the longer bolts). After that, I'll feel better about getting new tires.
Where's the best place to get/order one? It seems the best price is around $500-$525 + shipping. Some are showing a 14 day to ship date.
