Differential Case Installation

  1. Ensure drive pinion is installed in drive axle housing. Install assembled differential case, with Master Bearings (D-117 ) installed, into drive axle housing. Mount dial indicator on ring gear bolt side of differential case. See Figure.
    NOTE: Use Master Differential Bearings (D-136 ) on 10 1/2" and 11" drive axles.
  2. Place dial indicator tip on chalk mark made during step 3) of DETERMINING TOTAL DIFFERENTIAL SHIM PACK . Force ring gear mesh with drive pinion gear. Rock ring gear back and forth to allow teeth to mesh. While prying force is still applied to differential case, set dial indicator to zero.
  3. Force differential case away from drive pinion gear to obtain an indicator reading. Repeat this action of applying force to mesh ring gear into pinion and forcing gear away from pinion until a constant reading is obtained. Record reading. Remove dial indicator. Remove differential case from drive axle housing.
  4. Remove master bearings from differential case. Subtract reading found in step 3) of this procedure from total shim pack reading obtained under DETERMINING TOTAL DIFFERENTIAL SHIM PACK .
    NOTE: Reading found in step 3) of this procedure will determine shim size to be used on ring gear side of differential case. Use remaining portion of shim pack on opposite side of differential case after adding an additional .015" (.38 mm) on 9 3/4" axles or .010" (.25 mm) on 10 1/2" and 11" axles to preload the bearings.
  5. Place proper amount of shims on differential bearing hub (ring gear side). Drive or press differential bearing onto hub.
  6. Place calculated amount of shims on differential bearing hub (opposite ring gear side). Place additional .015" (.38 mm) on 9 3/4" axles or .010" (.25 mm) on 10 1/2" and 11" axles shim to preload bearings. Drive or press differential bearing onto hub.
  7. Mount dial indicator on differential housing to measure housing spread, in order to install differential case. See Figure. Preload dial indicator to .020" (.51 mm), then rotate gauge to zero dial. Using Drive Axle Housing Spreader (J-24385-01 ), spread drive axle housing .015" (.38 mm). DO NOT  spread housing more than specified, or housing damage may result.
  8. Remove dial indicator. Install races to differential case bearings. Install differential case into drive axle housing. If necessary, use a rawhide or rubber mallet to properly seat differential case into housing.
  9. Remove drive axle housing spreader. Install bearing caps and tighten to specification. See TORQUE SPECIFICATIONS  table.
