34 FRONT AXLE - 4 X 4 Check ring gear and pinion backlash in the three equally spaced points with dial indicators. Fig. 59 Backlash tolerance is 0.13 mm to 0.23 mm and should not vary more than 0.08 mm between points checked. High backlash is corrected by moving the ring gear closer to the pinion. Low backlash is corrected by moving the ring gear away from the pinion. These corrections are made by switching shims from one side of the differential case to the others. Note : If backlash is to specification, check the right gear and pinion tooth contact pattern, and adjust accordingly. Refer to the Rear Axle section for details. Install axle shafts through side gear spline. Place the snap ring in the shaft's groove. Fig. 60 Assemble Cylindrical roller bearing in carrier housing using Dolley to pressing cylinder roller bearing in housing Pt. no. 2704 5809 3306. Assemble the oil seals using installer pinion oil seal Pt. no. 2698 5890 3513 and handle universal Pt. no. 2698 5890 3506. Install the mounting brackets, assemble the new ones, if required and torque the four bolts (each side) to 54-75 N.m. Fig. 61 Note : Brackets are not interchangable. Apply sealent to cover plate surface. Fig. 62 The bead must be 1/8 to 1/4 in high and wide. Tighten the cover screw evenly to a torque of 38-45N.m. Allow one hour curing time before vehicle operation. Fill specified oil after curing. Fig. 60 Fig. 61 Fig. 62 Fig. 59 CONTOUROF BEAD DIAL INDICATOR WITHBRACKETRY RINGGEAR
