REAR AXLE - Differential Carrier <Vehicles with mechanical LSD> 27B-49 " HA BEARING CAP INSTALLATION/FINAL DRIVE GEAR BACKLASH ADJUSTMENT Adjust drive gear backlash as follows: race to the gear carrier. 2. Press the differential case to one side to measure the clearance of the side bearing outer race and the gear carrier. 3. Select two pairs of the side bearing spacer with the thickness derived from the sum of the clearance and a half of pre-load, 0.05 mm. 4. Remove the side bearing with special tools. NOTE Hook the claws of the special tool with the side bearing inner race by using the notches (two areas) of the LSD case side. 5. Assemble the selected side bearing spacers to each side. 6. Use special tools to press-fit the side bearing inner case into the LSD case. After installing the outer race, assemble the LSD case to the gear carrier. 7. Align the mating marks of differential carrier and the bearing cap with each other to tighten to the specified torque. · m 8. Measure the drive gear backlash. NOTE Measure at four points or more on the circumference of the drive gear. 9. If the backlash is not within the standard value, move the side bearing spacer as shown in the illustration to adjust the backlash. The increment of side bearing spacer must be coincided with the decreased amount. 10. Inspect the tooth condition at the final drive gear and make an adjustment if required. (Refer to P.27B-39.)
