Removal and Installation
REMOVAL
1. Remove the rear propeller shaft.
2. Remove the brake calipers and rotors.
3. Measure the total preload torque.
NOTE: Record the total preload torque measurement.
4. Remove the drive pinion nut using Tool.
Tool number: KV40104000 ( - )
5. Put matching marks on the companion flange and drive pinion using paint.
CAUTION: Use paint to make the matching marks. Do not damage the companion flange or drive pinion.
6. Remove the companion flange using suitable tool.
7. Remove the front oil seal using Tool.
Tool number: ST33290001 (J-34286)
INSTALLATION
1. Apply multi-purpose grease to the lips of the new front oil seal. Then drive the new front oil seal in evenly until it becomes flush with the gear carrier using Tool.
Tool number: ST15310000 ( - )
CAUTION:
^ Do not reuse front oil seal.
^ Do not incline the new front oil seal when installing.
^ Apply multi-purpose grease to the lips and differential gear oil to the circumference of the new front oil seal.
2. Install the companion flange to the drive pinion while aligning the matching marks.
3. Apply anti-corrosive oil to the threads of the drive pinion and the seating surface of the new drive pinion lock nut and new drive pinion lock nut washer. Then adjust the drive pinion lock nut tightening torque using Tool A, and check the total preload torque using Tool B.
Tool number
A: KV40104000 ( - )
B: ST3127S000 (J-25765-A)
Total preload torque: Refer to RFD-120, "Total Preload Torque". Assembly Inspection and Adjustment
^ The total preload torque should be within the total preload torque specification. When not replacing the collapsible spacer, it should also be equal to the measurement taken during removal plus an additional 0.56 Nm (0.06 Kg-m, 5 in-lb).
^ If the total preload torque is low, tighten the drive pinion lock nut in 6.8 Nm (0.69 Kg-m, 5 ft-lb) increments until the total preload torque is met.
CAUTION:
^ Do not reuse drive pinion lock nut or drive pinion lock nut washer.
^ Apply anti-corrosive oil to the threads of the drive pinion and the seating surface of the new drive pinion lock nut.
^ Adjust the drive pinion lock nut tightening torque to the lower limit first. Do not exceed the drive pinion lock nut specified torque. Refer to Exploded View RFD-119.
^ Do not loosen drive pinion lock nut to adjust the total preload torque. If the total preload torque exceeds the specifications, replace the collapsible spacer and tighten it again to adjust.
^ After adjustment, rotate drive pinion back and forth 2 to 3 times to check for unusual noise, rotation malfunction, and other malfunctions.
4. Installation of the remaining components is in the reverse order of removal.
CAUTION: Check the differential gear oil level after installation.
