Oil should be right at the lowerest portion of the fill hole. 4) With a catch pan placed below the drain plug, remove the drain plug with the 14mm Allen socket. 5)When the oil has completely drained, place back the drain plug with a new seal-ring and torgue to 48ft-lb. 6)Refill the diff with the correct oil until the oil begins to just trickle out the fill plug. 7)Place back the the fill plug with a new seal-ring and torque to 48ft-lb.
