Front Axle - 181FBI

REMOVAL
1. Raise and support the vehicle.
2. Remove wheel and tire assemblies.
3. Remove brake rotors and calipers.
4. Mark propeller shaft and pinion yoke for installation reference.
5. Remove propeller shaft from the yoke.
6. Rotate pinion gear three or four times.
7. Record rotating torque of the pinion gear with an inch pound torque wrench for installation reference.
8. Hold pinion yoke with Wrench 6958 and remove the pinion nut and washer.





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

INSTALLATION





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





2. Install yoke on the pinion gear with Installer W-162-D, Cup 8109 and Holder 6958 (Fig. 28).

CAUTION: Do not exceed the minimum tightening torque when installing the pinion yoke retaining nut at this point. Damage to the pinion bearings may result.

3. Install the pinion washer and a new nut on the pinion gear shaft. Tighten the nut only enough to remove the shaft end play.
4. Tighten pinion nut to 217 Nm (160 ft. lbs.).





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 Holder 6958 to hold the pinion yoke, and tighten pinion shaft nut in 6.8 Nm (5 ft. lbs.) increments until proper rotating torque is achieved.
7. Install propeller shaft with reference marks aligned.
8. Check and fill the gear lubricant.
9. Install the brake rotors and calipers.
10. Install wheel and tire assemblies.
11. Lower the vehicle.
