31 FRONT AXLE - 4 X 4 Note : Tighten the nut only enough to remove the shaft end play. Then continue to tighten the nut in small increments until the correct bearing preload torque is attained. Exercise care during the bearing preload torque adjustment. DO NOT OVERTIGHTEN or loosen and then retighten the nut. Do not exceed the bearing preload torque. If exceeded the collapsible preload spacer on the pinion gear shaft will have to be replaced. The bearing preload torque will have to be readjusted afterward. Using a torque wrench, ensure that the rotating torque of pinion is between 1.7 - 3.9 N.m. with new bearings Fig. 49 Clean & Assemble dummy differential bearings Pt. no. 2704 5890 3309 onto case. Fig. 50 Assemble differential case into carrier [Less Ring Gear] Mount dial indicator and locate tip of indicator on flat surface of case. Force the differential case as far as possible in the direction towards the indicator. Fig. 51 With force still applied, set indicator to zero (0). Force the differential assembly as far as it will go, in opposite direction. Repeat until the same reading is obtained. Record the reading. Fig. 52 This is the total amount of shims required. This is measurement A. Fig. 50 Fig. 51 Fig. 52 Fig. 49
