Rear Axle - 226RBA

REMOVAL
1. Raise and support the vehicle.
2. Remove wheel and tire assemblies.
3. Remove rear brake calipers and rotors.
4. Mark propeller shaft and pinion yoke for installation reference and remove propeller shaft.
5. Rotate pinion gear a minimum of ten times and verify pinion rotates smoothly
6. Record rotate torque of the pinion gear, with an inch pound torque wrench.





7. Hold pinion yoke with Spanner Wrench 6958 and remove pinion nut and washer (Fig. 35).





8. Remove pinion yoke with Remover C-452 and Wrench C-3281 (Fig. 36).





9. Remove pinion shaft seal with Remover 7794-A and slide hammer (Fig. 37).
10. Remove front pinion bearing using a pair of pick tools to pull the bearing off the pinion gear shaft.

NOTE: If the pinion bearing becomes bound on the pinion shaft, lightly tap the end of the shaft with a rawhide/rubber mallet.

11. Remove the collapsible spacer.

INSTALLATION
1. Install a new collapsible spacer on pinion shaft.
2. Install pinion front bearing on the pinion shaft.





3. Apply a light coating of gear lubricant on the lip of pinion seal and install seal with an appropriate installer (Fig. 38).





4. Install yoke with Installer C-3718 and Spanner Wrench 6958 (Fig. 39).
5. Install yoke washer and new nut on the pinion gear. Tighten the nut to remove all end-play. Tighten the nut to a minimum torque of 298 Nm (220 ft. lbs.).

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

NOTE: New collapsible spacers require high initial torque to start the collapsing of the spacer. This may reach 678 Nm (500 ft. lbs.).





6. Hold yoke with Spanner Wrench 6958 and a torque wrench set at 380 Nm (280 ft. lbs.), (Fig. 40) slowly tighten the nut in 6.8 Nm (5 ft. lbs.) increments until the rotating torque is achieved. Measure the rotating torque frequently to avoid over crushing the collapsible spacer (Fig. 41).





7. Check rotating torque with an inch pound torque wrench (Fig. 41). The rotating torque of the pinion gear should be, the reading recorded during removal plus an additional 0.56 Nm (5 in. lbs.).
8. Install propeller shaft with reference marks align.
9. Install rear brake rotors and calipers.
10. Add gear lubricant, if necessary.
11. Install wheel and tire assemblies.
12. Remove supports and lower vehicle.
