Symptoms of worn stock LSD?

I'm pretty confident my 135k mile stock LSD is no longer functioning. We were pulling on gravel and I saw 1 wheel spin while the other just sat there. Its not that big of a deal for me as is, but i was wondering if it would present similar symptoms as a slipping transmission? Is there a loss of mileage possible? Does it prevent power from making it to the wheels?

No, nothing like that. The worst thing that can be happening is those frictions (clutches) are so worn that you have a conventional "open" diff. No loss of getting the power to the road.

Did it ever work for you though? See the problem with the Factory LS is that Ford adds Way too much Friction Modifier to the oil and kind of prevents it from working well (I think it's less complaints for them to deal with). So, if you don't know the history of it's performance you could try to change the fluid that contains no modifier then put in about 1/4 of what's recommended and see it it actually Does work (then add just enough modifier to stop excessive clutch chatter).

You can also replace those clutches if that's all it needs....

My LS actually works pretty well
