My stepfather's truck has a Dana 60 limited slip rear axle with 3.73 gears. Today, when stuck in the snow(common in central New York), I noticed that only one tire was spinning, meaning that the limited slip diff isn't functioning as it should. Does this mean that the clutch packs in the diff are shot or would the truck not move at all if this were the case? I've never seen what happens when a limited slip wears out... does it act like an open diff?
Thanks for any input.
My '86 4Runner went to the bone-yard November 29, 2004 at 10am after roughly 430,000 miles on the original engine and transmission. :-( Looking for something else to wheel in...

Thanks for any input. Dead clutch pack? Maybe. Or, it could be as simple as the WRONG GEAR LUBE! There's a gazillion lubes out there, and not all of them have the friction additives for LSDs. Try some different grease. I think that you're looking for the API Spec GL-5. Or, you can buy the friction additive from many parts stores. Try that first. Anyone else know for sure? Zuk? 4Crawler? Anybody?

Nothing's wrong with it, it's acting as a LSD should when stuck in the snow and neither wheel has any traction.
Some light action on the brake pedal sometimes helps it send power to both wheels.

fourwd1: Seemed to me like one wheel had better traction than the other(one side was on packed snow, the other was on smooth ice, ice skating rink style :-P ).
As far as the oil in the differential, The bottle used to fill it says in very plain language that it is for limited slip differentials. In fact, it was purchased at a GM dealership(the axle is for a Chevy 3/4 ton diesel). Though there are no guarantees that the stealership wouldn't lead a customer astray, I'm reasonably certain it is the right stuff.
Thanks for the help, everyone.

Sounds like the clutch packs are worn. You might replace them and shim the spring. I haven't taken one of those apart but if it's anything like the Supra LSD's, shimming the spring hels a ton.
