Rear Axle - 267RBI

REMOVAL
1. Raise and support the vehicle.
2. Scribe a mark on the universal joint, pinion yoke, and pinion shaft for reference.
3. Disconnect the propeller shaft from the pinion yoke. Secure the propeller shaft in an upright position to prevent damage to the rear universal joint.
4. Remove the wheel and tire assemblies.
5. Remove the brake drums to prevent any drag. The drag may cause a false bearing preload torque measurement.
6. Rotate the pinion yoke three or four times.
7. Measure the amount of torque necessary to rotate the pinion gear with a (inch lbs.) dial-type torque wrench. Record the torque reading for installation reference.
8. Hold the yoke with Wrench 6719. Remove the pinion shaft nut and washer.





9. Remove the yoke with Remover C-452 (Fig. 22).
10. Remove the pinion shaft seal with suitable pry tool or slide-hammer mounted screw.

INSTALLATION
1. Clean the seal contact surface in the housing bore.
2. Examine the splines on the pinion shaft for burrs or wear. Remove any burrs and clean the shaft.

NOTE: The outer perimeter of the seal is pre-coated with a special sealant. An additional application of sealant is not required.

3. Apply a light coating of gear lubricant on the lip of pinion seal.
4. Install the new pinion shaft seal with an appropriate installer.
5. Position the pinion yoke on the end of the shaft with the reference marks aligned.





6. Seat yoke on pinion shaft with Installer D-191 and Yoke Holder 6719 (Fig. 23).
7. Remove the tools and install the pinion yoke washer and nut.





8. Hold pinion yoke with Yoke Holder 6719 and tighten shaft nut to 289 - 380 Nm (220 - 280 ft. lbs.) (Fig. 24). Rotate pinion shaft several revolutions to ensure the bearing rollers are seated.





9. Rotate the pinion shaft using an inch pound torque wrench. Rotating resistance torque should be equal to the reading recorded, plus a small amount for the drag the new seal will have (Fig. 25).

NOTE: The bearing rotating torque should be constant during a complete revolution of the pinion. If the rotating torque varies, this indicates a binding condition.

10. Install the propeller shaft with the installation reference marks aligned.
11. Tighten the universal joint yoke clamp screws to 19 Nm (14 ft. lbs.).
12. Install the brake drums.
13. Add gear lubricant to the differential housing, if necessary. Refer to the Lubricant Specifications for gear lubricant requirements.
14. Install wheel and tire assemblies and lower the vehicle.
