Install the yoke washer AND A NEW NUT on the pinion gear. Tighten the nut to 216 Nm (160 ft. lbs.).
CAUTION: Never loosen the pinion gear nut to decrease the pinion gear bearing preload torque. If the specified preload torque exceeds 352
Nm (260 ft. lbs.) a new collapsible spacer must be installed. The torque sequence will have to be repeated.
(9)
Use Flange Wrench C-3281 to retain the yoke. Slowly tighten the nut in small increments until the rotating torque is achieved. Measure the
preload torque frequently to avoid over-tightening the nut.

Check bearing preload torque with an inch pound torque wrench. The torque necessary to rotate the pinion gear should be;
-
Original Bearings: 1 to 3 Nm (10 to 20 in. lbs.).
-
New Bearings: 1.5 to 4 Nm (15 to 35 in. lbs.).
