Side Gear Back Clearance

WARNING: This page is about a different car, the 2006 Nissan Titan. However, it is still accessible from the selected car via links, so may be relevant.
  1. Place the differential case straight up so that the side gear to be measured is upward.

    G04756689
  2. Using feeler gauges, measure the clearance between the side gear back and differential case at three different points, while rotating the side gear. Average the three readings to calculate the clearance. (Measure the clearance of the other side as well.)

    Side gear back clearance: 0.20 mm (0.0079 in) or less 

    • If the side gear back clearance is outside of the specification, use a thicker or thinner side gear thrust washer to adjust. Refer to "SIDE GEAR THRUST WASHER ".

      If the side gear back clearance is greater than specification: 

      Use a thicker side gear thrust washer. 

      If the side gear back clearance is less than specification: 

      Use a thinner side gear thrust washer. 

    CAUTION:
    • Insert feeler gauges with the same thickness on both sides to prevent side gear from tilting.
    • Each gear should rotate smoothly without excessive resistance during differential motion.
    • Select a side gear thrust washer for right and left individually.

    NOTE: Side gear back clearance is clearance between side gear and differential case for adjusting side gear backlash.
