The most crucial step when installing the new differential is to measure backlash on the ring gear using a dial gauge indicator. Measure four points on the ring gear within 90 degrees apart to get a reading in tolerances. The backlash is within standard if at one point of measurement, the ring gear backlash is within the standard, minimum measurement of 0.05mm or above and the difference between the maximum and minimum measurements do not exceed 0.07mm. Use a pair of needle-nose pliers to adjust the screws and tighten the endcaps to 33 lb-ft when complete.
