Just pull your rear cover. So you spend $3.50 on a gasket ... count teeth, and look for the zexel -- you'll find out what you have inside. And, no, it's not an always-locked diff.

The torsen is torque sensitive, not speed sensitive, so putting it on a lift and spinning one wheel will make it act like an open differential.

Since its a torsen, thats perfectly normal, do not get furious!
