For example, if the measurement is 40.869 mm (1.609 in), select the 40.792 mm (1.606 in) 14. If the measurement obtained in step 11 is less than 40.488 mm (1.594 in), then reduce the left side gear thrust washer or the right side gear shim thickness in order to increase the 15. If the measurement obtained in step 11 is greater than 41.120 mm (1.622 in), then increase the left side gear thrust washer or the right side gear shim thickness in order to decrease the 16. Recheck the left and/or right side gear backlash and adjust as necessary. 17. Recheck the thrust block clearance and adjust as necessary. LOCKING DIFFERENTIAL ASSEMBLE (9.5 INCH AXLE) IMPORTANT: The backlash must be rechecked and adjusted to specification anytime the left and/or the right thrust washers IMPORTANT: The left and right side gear backlash and thrust block thickness measurement must be completed before the components of the
