5. Using the special tools, mount a suitable backlash dial indicator allowing the indicator tip to contact the drive side of the ring gear tooth through
the drain plug hole.
6. Rotate the left halfshaft inner CV joint to move the ring gear fore and aft to measure the backlash between the ring gear teeth and the pinion teeth.
Record the backlash.
7. Remove the dial indicator and rotate the driveshaft to turn the differential ring gear. Position the dial indicator and record the backlash in four
places around the ring gear.
8. Proceed as follows:
-
If the backlash is outside the range of 0.254 mm-0.305 mm (0.010-0.012 in), remove the differential for further investigation.
-
If the backlash is within specification, remove the tools, install the drain plug and refill the axle to specification.
