Pinion Flange & Oil Seal: Installation
- 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
).NOTE: If oil seal becomes cocked during installation, remove seal and install NEW oil seal.
- Align marks on companion flange and pinion. Apply a small amount of lubricant to companion flange splines. Install companion flange and NEW pinion nut. Hold companion flange or end yoke, and gradually tighten nut while rotating pinion.
- Check pinion bearing preload often, until correct preload is obtained. DO NOT
back off pinion nut to reduce preload. See DIFFERENTIAL SPECIFICATIONS
.NOTE: If desired preload is exceeded, a NEW collapsible spacer must be installed. Tighten nut to obtain proper preload.
- Remove plug from transmission extension housing. Install front end of drive shaft on transmission output shaft. Connect rear end of drive shaft to companion flange, aligning scribed marks.
- Apply locking compound to drive shaft bolt threads and tighten bolts to specification. See TORQUE SPECIFICATIONS . Fill differential until fluid level is about 1/4" below bottom of filler plug hole.
