(b) Coat the threads of the rear drive pinion nut with hypoid gear oil LSD.

(c) Using SST and a torque wrench, hold the rear drive pinion companion flange and tighten the rear drive pinion nut.









SST : 09330-00021

Torque : 338 Nm (3447 kgf-cm, 249 ft-lbf) or less

NOTICE:
* Tighten the rear drive pinion nut to approximately 100 N*m (1020 kgf*cm, 74 ft.*lbf), and then tighten it further while checking the differential drive pinion preload.
* Apply hypoid gear oil LSD to the rear drive pinion nut and the threads of the differential drive pinion.

24. ADJUST DIFFERENTIAL DRIVE PINION PRELOAD

(a) Using a torque wrench, measure the starting torque of the differential drive pinion.

HINT
* The backlash between the differential drive pinion and differential ring gear should allow enough movement of the differential drive pinion to allow this measurement to be performed.
* Make sure not to include the preload of the differential ring gear (rear differential case sub-assembly) in the measurement of the differential drive pinion preload.





Differential Drive Pinion Preload (at Starting):





* If the preload is less than the specified minimum value, check the preload while retightening the rear drive pinion nut by 5 to 10° to adjust it so that it is within the specified range.

Torque:

338 N*m (3447 kgf*cm, 249 ft.*lbf) or less

* If the preload is less than the specified minimum value even when the tightening torque of the rear drive pinion nut is more than the specified maximum value, loosen the rear drive pinion nut and check that the threads of the rear drive pinion nut and differential drive pinion are not stripped.

* If the threads are not stripped, replace the rear differential drive pinion bearing spacer. Apply hypoid gear oil LSD to the threads of the differential drive pinion and repeat the procedure.
