HINT: Measure at 3 or more positions around the circumference of the ring gear. If the backlash is not within the specification, adjust or repair the side bearing preload as necessary. Fig. 38: Measuring Backlash Of Ring Gear 4. INSPECT DIFFERENTIAL SIDE GEAR BACKLASH a. Using a dial indicator, measure the side gear backlash while holding one pinion gear toward the case. Standard backlash: 0.05 to 0.20 mm (0.00197 to 0.00788 in.) If the backlash is not within the specified value, replace the side gear thrust washer with one of a Fig. 39: Measuring Side Gear Backlash 5. INSPECT DIFFERENTIAL DRIVE PINION PRELOAD a. Using a torque wrench, measure the preload of the backlash between the drive pinion and ring gear. Standard drive pinion preload (at starting): 0.85 to 1.37 N*m (9 to 13 kgf*cm, 8 to 12 in.*lbf) If necessary, disassemble and inspect the differential.
