With the spacers installed on the back of the differential side
gears, install the gears into the differential case. If reusingparts, install them in their original positions noted during disas-sembly.If using new differential side gears, install medium thicknessspacers 1.0mm (0.039in.).Install the washers on the back of the pinion gears. Install gearsinto the differential case, then insert the pinion shaft.Measure the backlash between the side gear and the piniongear.Backlash should be 0.025-0.150 mm (.0010-.0059 in.) and theright and left hand gear pairs should have equal backlash. If thebacklash is out of specification, disassemble and reassembleusing different spacers for the correct backlash.-
Standard value: 0.025-0.150 mm (.0010-.0059 in.)
