2008 Cadillac Escalade ESV Differential Seal

If the rotating torque is exceeded, the pinion will have to be removed and a new collapsible spacer installed. Tighten the pinion nut until the pinion end play is just taken up. Rotate the pinion while tightening the nut to seat the bearings. Tighten the pinion nut, in small increments, as needed, until the torque required to rotate the pinion is 0.40-0.57 N.m (3-5 lb in) greater than the torque recorded during removal.

When removing the propeller shaft, do not attempt to remove the shaft by pounding on the yoke ears or using a tool between the yoke and the universal joint. If the propeller shaft is removed by using such means, the injection joints may fracture and lead to premature failure of the joint. You should carefully remove the oil seal from the bore, and not distort or scratch the aluminum case.
