Door tag axle code. If its a number and a letter then you have a limited slip.
the diff is a set of clutch packs and they are notorious for wearing out. If you have the limited slip then you can add a few ounces or friction modifier and possibly cure some of it if the wear isn't too bad.
Run a search for "door tag decoder" on here and you'll find a chart...id do it for ya but im on my phone and its not as easy.
