thanks for the help
so my next question is, do I fill the diff. until it leaks out the hole? or do I leave it 1/2" from the bottom of the fill hole?

According to the 2003 Silverado Owner's Manual for the Rear Axle, How to Check Lubricant p.5-55 " The proper level for the 1500 Series is from 5/8 inch to 1 5/8 inch below the bottom of the filler plug hole."
I am not sure if filling it to the bottom of the filler plug hole will cause any problems with expansion and potential leaking or not.
Edit: Well a day late and a $$ short I guess.

well I read about a guy that had a problem with expansion and leaking out, so he just unscrewed the fill plug, and it basically pushed out all the excess, and he's never had that problem since, but we'll see

It chatters bassically, as they are trying to resist slipping rather than slip smoothly in the corner.
Good luck!

If not you can purchase the additive at most parts stores. K&W(I think) is the company most parts houses sell. It comes in a tube and is usually near the rear end dope. You can also get it from the dealer. But if yours doesn't chatter when you go around a corner you shouldn't have any problem.

I am unsure if synthetics are ok in clutched units. I haven't ran one in years and when I did I used the cheap **** with an additive. Someone posted earlier in the thread about not using synthics or something of that sort. Just make sure the fluid says somewhere on it that it is compatible with limited slip differentials. If it chatters you should be able to feel it as well.
