REDUCTION DIFFERENTIAL: REASSEMBLY
Inspection and Adjustment Side Bearing Preload
Reduction Gear Backlash
Tie a wire on the reduction gear tooth and hook a spring scale to the wire. Tighten the side bearing nuts while reading the spring scale until the specified preload is obtained.
Adjust the backlash between the reduction gear and pinion after installing the differential carrier assembly to the transmission case. To measure the backlash, set a dial indicator with its spindle pointing squarely to the tooth face of the reduction gear. With the pinion held, move the gear back and forth to read the indicator. Adjust the backlash using the left and right side bearing nuts and pinion shims.
NOTE Before measuring the preload, tap the back of the reduction gear with a copper hammer while rotating the gear to center between bearing.
