RAM 3500 Truck 4WD V10-8.0L VIN W (1997)
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.
12. The seal replacement is unacceptable if the final pinion nut torque is less than 285 Nm (210 ft. lbs.).
13. Install the propeller shaft with the installation reference marks aligned.
14. Tighten the universal joint yoke clamp screws to 19 Nm (14 ft. lbs.).
15. Install the brake drums.
16. Install wheel and tire assemblies and lower the vehicle.
17. Check the differential housing lubricant level.
Rear Axle - 248 or 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, or equivalent. Remove the pinion shaft nut and washer.
9. Remove the yoke with Remover C-452, or equivalent.
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.
3. Inspect pinion yoke for cracks, worn splines and worn seal contact surface. Replace yoke if necessary.
NOTE: The outer perimeter of the seal is pre-coated with a special sealant. An additional application of sealant is not required.
4. Apply a light coating of gear lubricant on the lip of pinion seal.
