Rear Axle - 194RBI

REMOVAL
1. Raise and support the vehicle.
2. Remove wheel and tire assemblies.
3. Remove the brake drums.
4. Mark the propeller shaft and pinion yoke for installation reference.
5. Remove the propeller shaft from the yoke.
6. Rotate the pinion gear three or four times.
7. Measure the amount of torque necessary to rotate the pinion gear with a inch pound dial-type torque wrench. Record the torque reading for installation reference.
8. Hold the yoke with Wrench 6958 and remove the pinion nut and washer.





9. Remove the pinion yoke with Remover C-452 and Wrench C-3281 (Fig. 26).
10. Remove the seal with a pry tool or slide hammer mounted screw.

INSTALLATION





1. Apply a light coating of gear lubricant on the lip of pinion seal and install seal with an appropriate installer (Fig. 27).





2. Install yoke on the pinion gear with Screw 8112, Cup 8109 and Spanner Wrench 6958 (Fig. 28).

CAUTION: Do not exceed the minimum tightening torque 271 Nm (200 ft. lbs.) when installing the pinion yoke at this point. Damage to the collapsible spacer or bearings may result.

3. Install yoke washer and new nut on the pinion gear and tighten nut until there is zero bearing endplay.
4. Tighten the nut to 271 Nm (200 ft. lbs.).

CAUTION: Never loosen pinion gear nut to decrease pinion gear bearing rotating torque and never exceed specified preload torque. If preload torque or rotating torque is exceeded a new collapsible spacer must be installed.





5. Rotate the pinion shaft using an inch pound torque wrench. Rotating torque should be equal to the reading recorded during removal plus an additional 0.56 Nm (5 inch lbs.) (Fig. 29).





6. If the rotating torque is low, use Wrench 6958 to hold the pinion yoke (Fig. 30), and tighten the pinion shaft nut in 6.8 Nm (5 ft. lbs.) increments until the proper rotating torque is achieved.

CAUTION: If the maximum tightening torque 474 Nm (350 ft. lbs.) is reached prior to reaching the required rotating torque, the collapsible spacer may have been damaged. Replace the collapsible spacer.

7. Install the propeller shaft with the reference marks aligned.
8. Add gear lubricant to the differential housing, if necessary.
9. Install the brake drums.
10. Install wheel and tire assemblies.
11. Lower the vehicle.
