Limited slip, do I have it do I need friction modifer

Just use a little RTV.

There's one pretty obvious way you can tell if you lave limited slip. Put it in 2WD, get on a gravel road or grass and goose it. Do both wheels spin, or just one? If just one, LS is either not working or not there.

If it has a factory limited slip there will be a warning sticker on the inside of the glove box door. I have a 98 sport that I ordered with the LSD.

Look for a small rectangular metal tag that says friction modifer needed. I think you can cover all the bases by just using friction modifier, if you don't have one it won't hurt to use it, or just run synthetic, that already has the additive built in.

Rich, I also am unaware of what kind of rear diff I have and need to change the fluid. If I add synthetic then I will not have to worry about an additive? and is synthetic ok to use on a regular open diff if thats what I end up having? Thanks in advance!

Maybe. My 2000 had the factory Trak-Lok when I got it, but never had the glovebox sticker.

Synthetic is fine for all uses. If you believe you have a limited slip, check the bottle to make sure it says compatible with limited slips. Most synthetics are, although they also state that if you experience clutch chatter add the limited slip additive.
