Backlash Adjustment

WARNING: This page is about a different car, the 2003 GMC Sierra, 2003 GMC Cab & Chassis Sierra, 2003 Chevrolet Silverado, and 2003 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.

Adjust the backlash by means of moving the side bearing adjuster sleeves which move the case and ring gear assembly closer to or farther from the pinion. Also use the adjuster sleeves in order to set the side bearing preload.

If the left side adjuster sleeve is moved in, along with an equal outward movement of the right side adjuster, the backlash will increase.
If the left side adjuster sleeve is moved out, along with an equal inward movement of the right side adjuster, the backlash will decrease.
