       09330-00030

       Limit Torque Value

       370 N*m (3773 kgf*cm, 273 ft.*lbf) or less

15. INSPECT DIFFERENTIAL DRIVE PINION PRELOAD

    1. Using a torque wrench, measure the preload.

       Standard Preload (at Starting)

       Item	Specified Condition

       Used bearing	0.49 to 0.78 N*m (5 to 7 kgf*cm, 4.3 to 6 in.*lbf)

       If the result is not as specified, adjust the preload.

       Standard Total Preload (at Starting)

       Item	Specified Condition
       New bearing	1.2 to 2.45 N*m (13 to 24 kgf*cm, 11 to 21 in.*lbf)
       Used bearing	0.71 to 1.66 N*m (8 to 16 kgf*cm, 7 to 14 in.*lbf)
