    Torque spec and socket size reference guide

    Hi. You should remove this info before someone causes catastrophic damage to their jeep. The manual specifically says do not tighten past 160 ft lbs on the pinion nut or you could destroy the bearing This list says 210 ft lbs. Anyone that saw this and just went for it is going to be ******.
