Ring & Pinion Gear Backlash

WARNING: This page does not describe the selected car, but rather 17 other vehicles, including the 2002 GMC Yukon XL, 2002 GMC Yukon, 2002 GMC Sierra, 2002 GMC Savana Special, and 2002 GMC Savana Camper Special. However, it is still accessible from the selected car via links, so may be relevant.
  1. Mount Dial Indicator (J-39704) onto drive axle housing. See Fig 1 . Place dial indicator tip at heel end of ring gear tooth. Check backlash at 3 equally spaced locations around ring gear.
  2. Backlash should be .005-.009" (.13-.23 mm). Ensure variation between points checked is not more than .002" (.05 mm). High backlash is corrected by moving ring gear closer to drive pinion. Low backlash is corrected by moving ring gear away from pinion.
  3. To adjust backlash, remove both differential case side bearings. Move shims from one side to other.
  4. When backlash is correct, check ring gear tooth contact pattern. See DRIVE AXLE - GEAR TOOTH CONTACT PATTERNS article in GENERAL INFORMATION.
  5. To complete assembly, install cover using NEW cover gasket. Tighten cover bolts to specification. See TORQUE SPECIFICATIONS  . Install axle shafts. Fill drive axle with lubricant. See LUBRICATION  .
