Pinion Flange & Oil Seal: Installation
- Install NEW spacer on drive pinion. Install rear bearing on drive pinion. Install oil slinger in original direction of installation.
- Install NEW oil seal to correct depth on differential carrier. See DRIVE PINION OIL SEAL DEPTH INSTALLATION SPECIFICATIONS table.DRIVE PINION OIL SEAL DEPTH INSTALLATION SPECIFICATIONS
Application In. (mm) All Models .177 (4.49) - Apply grease on lip of oil seal. Install companion flange on drive pinion. Apply grease to threads of NEW drive pinion nut. Install washer (if equipped) and drive pinion nut on drive pinion.
- Tighten drive pinion nut to MINIMUM specification. See TORQUE SPECIFICATIONS . Using INCH-lb. torque wrench installed on drive pinion nut, measure drive pinion rotating torque to determine drive pinion bearing preload. Drive pinion rotating torque should be within specification. See AXLE ASSEMBLY SPECIFICATIONS table.
- If drive pinion rotating torque exceeds specification, replace spacer and repeat procedure. If drive pinion rotating torque is less than specified, tighten drive pinion nut in small increments until correct rotating torque is obtained. DO NOT exceed MAXIMUM drive pinion nut torque. See TORQUE SPECIFICATIONS . If maximum torque is exceeded, replace spacer and repeat procedure. DO NOT back off drive pinion nut.
- Once correct drive pinion rotating torque is obtained, stake drive pinion nut against drive pinion. To install remaining components, reverse removal procedure. Ensure reference marks on drive shaft companion flange and companion flange on differential are aligned. Tighten bolts/nuts to specification. See TORQUE SPECIFICATIONS . Fill differential with gear oil.
