Ring Gear Backlash

  1. Install bearing caps in original positions and tighten to 70-85 ft. lbs. Install dial indicator so plunger contacts ring gear teeth. Measure backlash at 4 locations around ring gear. Backlash should be 0.008 - 0.015". Readings should not vary more than 0.004" between any of the 4 readings.
  2. To decrease backlash, subtract from right shim thickness and add to left shim thickness. To increase backlash, add to right shim thickness and subtract from left shim thickness. Do not change total shim thickness, simply alter position of shims.
