Reassembling Differential

2004 Oldsmobile Bravada RWDSECTION Reassembling Differential
WARNING: This page is about a different car, the 2003 Chevrolet Corvette and 2002 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: If the pinion assembly components have not been replaced, reuse the original pinion housing shims. If the pinion assembly components have been replaced, see SELECTING DRIVE PINION SHIM for selection of the proper size shims.
  1. Assemble the drive pinion prior to rear axle assembly. See INSTALLING DRIVE PINION . Using the Installer (J 42157) and a hydraulic press, install the bearing into left cover.
  2. Install the oil seal into the left cover using the Installer (J 36797). Install the oil seal into the right cover using the J 36797.
  3. Install the pinion housing assembly and the selected shim or shims to the differential housing. See SELECTING DRIVE PINION SHIM . The use of M8 x 1.25 dowels or long bolts will ease in pinion housing/cage and shim installation and alignment.
  4. Install the pinion housing/cage bolts. Tighten the bolts to specification. See TORQUE SPECIFICATIONS .
  5. Install the "C" clip into the groove of the output shaft. See Figure. Apply Threadlocker® (1052942), or equivalent to the threads of the bolts and stud. Apply Threadlocker® only to the end of the stud that installs into the transmission mount. Install the transmission mount and bolts. Tighten the bolts to specification. See TORQUE SPECIFICATIONS . Install 2 M10 x 1.5 nuts onto the transmission stud. Install the stud into the mount. Tighten the stud to specification.
  6. Install the "O" ring to the groove of the right cover. Install the right cover and bolts. Tighten the bolts to specification. See TORQUE SPECIFICATIONS .
  7. Install the Dial Indicator Set (J 8001) onto the transmission stud. Position the tip of the dial indicator against the center of the ring gear tooth surface. See Fig 1. Install the Pinion Gear Holder (J 42164) into the splines of the pinion. J 42164 will retain the pinion in order to properly measure backlash. Move the right output shaft in both directions in order to measure the gear backlash. Measure the backlash in two to three locations. Measured backlash should be .0067-.0082 in. (.13-.21 mm).
