limited slip, it's just that, it limits the slip on the one wheel before the other side start to spin, there is a speed to it, if you punch it will engage and if you are on a slipery surface and you are going over 25 miles and start to slip it will slip to certain rpm than will engages,
a posi it's that it will engage as the wheel spin but it gives you that difference radious while turning, they have diferent one too
it's something like that, i can't remember well, there will be some body that will schime in and explain it better or say that i don't know what the hell i'm saying, :D
i just know how to install them

If you gonna replace it you might as well look for a bigger gear like 3.42's or 3.73's. I love 3.73'S. It mkaes the car feel like a 1,000 pounds lighter..

typically your looking at around 300 bux in labor to install it, even if the mesh pattern isn't off much at all(with a new carrier, but stock gears).

like it was mentioned averege $300, and it should not take more than 3 hours, the actual work, make sure you find a place that does rear ends, if not your rear will wind and you don't want that.
also get some gears too, like 3.42, that way you can keep the stock drive shaft, that's if you have 2.93 now, but if you have 2.56 you will need to rebalance the drive shaft, any higher than 3.42, you will need to replace the drive shaft.
if you put a posi you should get gears, since they are going to be in there, if not it will be another $300,to put gears

Theres actually quite a few people who have gone to 3.73's(from 2.56's even) with the stock driveshaft, and it didn't vibrate at over 100mph. Actually, the one I'm thinking of got his up to about 130, with 3.73's, and only 26" tires. IIRC, but I know it was atleast 120mph. It's more of a hit or miss kinda deal. Some can just go 3.73's and it's fine, others just flip the Drive shaft 180* if it vibes, and it's all good. and then a few have moved the DS a few spilnes at the trans side, and it was fine.

But yea, like he said, find a shop that does ALOT of rear end work, and will warrenty it. and adding gears while adding a posi, only costs as much as the gears them selves. Adding a posi, or adding a posi+gears will still only be about $300. I bet you could do it at your dealership if one of the guys knows how to do it, and is whilling to help you. READ how to do it, and with all the tools you have, I bet you could do it.

I haven't had any issues with my drive shaft with 3.73's either. I did replace the u-joints as preventive maintnence though, Seeing that I am a bit harder on my car than a usual pperson would be...
