Should be a tag on the rear diff somewhere stating the rear end designation. If not you could go to a dealer and get them to print out a build sheet, and on there it will tell you what it has.

Easy way to tell is to jack up the back end, put it in neutral and spin the rear tires. If they both spin the same way trac-lok. If one spins one way and the other spins the oppisite; open diff.

the main diffrence between a trac-lok and an open carrier is the clutches inside of it ... the way it works is simple ! your wheels spin tthe oil heat between the cluches , they stick together and both wheels start spining ! but in normal driving , a trak=loc operats the same way as an open carrier axle ! so if you jack it up on a lift you ll have to spin your wheel real real fast if you want to check it its limited slip or not !! so either find the tag , ask at dealler ship or wait till you change your axle fluid , remove the cover and look at it !!
