Here's how to tell: Jack the rear up by the center section and support the axle with jack stands. Put the Jeep in park or in gear if it's a manual. Grab a tire and see if it'll turn. If it will, you ain't gotta posi. If it won't turn you do. It's normal for a standard opened faced differential to spin one, the other or both on slippery surfaces such as snow mud ice and the like.
