Pinion Flange & Oil Seal: Installation

NOTE: If oil seal becomes cocked during installation, remove seal and install new oil seal.

Ensure pinion shaft splines are free of burrs. Remove burrs with fine crocus cloth if necessary. Lubricate area between oil seal lip, and install oil seal into axle housing using Pinion Oil Seal Replacer (T83T-4676-A).
Align marks on pinion flange and pinion. Apply a small amount of lubricant to pinion flange splines. Install pinion flange and NEW pinion nut. Hold pinion flange and gradually tighten nut while rotating pinion.

NOTE: If desired preload is exceeded, a NEW collapsible spacer must be installed. Tighten nut to obtain proper preload.

Check pinion bearing preload often, until correct preload is obtained. See DIFFERENTIAL SPECIFICATIONS . DO NOT back off pinion nut to reduce preload. Connect rear end of drive shaft to pinion flange, aligning scribed marks.
Apply locking compound to drive shaft bolt threads and tighten bolts to specification. See TORQUE SPECIFICATIONS . Fill differential with proper lubricant until fluid level is about 1/4" below bottom of filler plug hole. See LUBRICATION . To complete installation, reverse removal procedures.
