When replacing the rear drive pinion companion flange and rear differential carrier oil seal, be sure to check the preload.
If the rear drive pinion companion flange and rear differential carrier oil seal were replaced without checking the preload, replace the torque vectoring differential carrier assembly.
Before installation of each part, thoroughly clean and dry it. Then apply gear oil to it. Do not use alkaline chemicals to clean aluminum parts, rubber parts or ring gear set bolts. Also, do not use non-residue solvent or other cleaning oils to clean O-rings, oil seals or rubber parts.

5.INSPECT RUNOUT OF REAR DRIVE PINION COMPANION FLANGE SUB-ASSEMBLY
| *a | Vertical Runout |
| *b | Lateral Runout |
| *c | 30 mm (1.18 in.) |
Using a dial indicator, measure the runout of the rear drive pinion companion flange vertical runout and lateral runout.
| Item | Specified Condition |
|---|---|
| Vertical runout | 0.1 mm (0.00394 in.) |
| Lateral runout | 0.1 mm (0.00394 in.) |
Measure the runout of the rear drive pinion companion flange horizontally at a position 50 mm (1.97 in.) away from the center of the differential drive pinion shaft.
If the runout is more than the maximum value, replace the rear differential carrier assembly.
6.INSPECT TOTAL PRELOAD
When replacing the rear drive pinion companion flange and rear differential carrier oil seal, be sure to check the preload.
If the rear drive pinion companion flange and rear differential carrier oil seal were replaced without checking the preload, replace the torque vectoring differential carrier assembly.
Using a torque wrench, check the starting torque (total preload) with the teeth of the drive pinion and ring gear in contact.
The torque wrench should be installed as shown in the illustration.
Record the measured value as it is used during assembly.
For a more accurate measurement, rotate the bearing forward and backward several times before the measurement.
