Front Axle - 248FBI
REMOVAL1. Raise and support the vehicle.
2. Remove wheel and tire assemblies.
3. Remove brake calipers and rotors
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 lbs.) dial-type torque wrench. Record the torque reading for installation reference.
Fig. 12:
8. Remove the pinion yoke nut and washer. Use Remover C-452 and Wrench C-3281 to remove the pinion yoke (Fig. 12).
9. Use suitable pry tool or slide hammer mounted screw to remove the pinion shaft seal.
INSTALLATION
Fig. 13:
1. Apply a light coating of gear lubricant on the lip of pinion seal. Install seal with Installer 8108 and Handle C-4171 (Fig. 13).
Fig. 14:
2. Install yoke on the pinion gear with Installer C-3718 and Holder 6719 (Fig. 14).
CAUTION: Do not exceed the minimum tightening torque when installing the pinion yoke retaining nut. Damage to collapsible spacer or bearings may result.
3. Install a new nut on the pinion gear. Tighten the nut only enough to remove the shaft end play.
Fig. 15:
4. Rotate the pinion shaft using a (inch lbs.) torque wrench. Rotating torque should be equal to the reading recorded during removal, plus an additional 0.56 Nm (5 inch lbs.) (Fig. 15).
Fig. 16:
5. If the rotating torque is to low, use Holder 6719 to hold the pinion yoke (Fig. 16), and tighten the pinion shaft nut in 6.8 Nm (5 ft. lbs.) until proper rotating torque is achieved.
6. Align the installation reference marks and attach the propeller shaft to the yoke.
7. Check and add lubricant to axle, if necessary. Refer to Specifications for lubricant requirements.
8. Install brake rotors and calipers.
9. Install wheel and tire assemblies.
10. Lower the vehicle.
