    Just got a 04 TJ unlimited and am changing all the fluids so I know when it was done last and look at the diff gears to make sure they are ok. Added Mobil 1, 70 w - 140 but how do I know if I have Trac -Loc or not? The rear didn’t look like a possi set up but was beefier than the front. Tags on the rear dif show - 52114210AA T-L (traction lock?) and 80w90 60 oz + FM4 oz (quantity with additive ?). Front tag had 52099200 AE, 3 78 611312-4.

    The way I have done this, is jack up the axel, with both tires off the ground, and spin one by hand. If the other side spins the same way, you have a No-Slip, or Trac-Lok. If it spins opposite, then its an open diff.
