Its actully in good shape. Didnt leak at all when it was in my rig, ball joints seem fine as my tires wore even and the Jeep tracked well with the axle. currently the passenger side looks as if it was leaking, but it wasnt. I took the unit hub off because I was going to use it on an other axle (has good hubs) but ended up not doing anything with it, so it sat without a hub for a few weeks in my garage and it dripped out what little oil was in the vac-dico housing. Has 3.55's.
