    20. NOTE: Use a dial indicator with a minimum travel capability of 5.08 mm (0.200 in).
    NOTE: The rear axle uses a combination of differential bearing shims and selective outboard spacers to control differential case end play. The old outboard spacers provide a good starting point when setting end play. However, if additional shimming is necessary, beyond what the hardened differential bearing shims can provide, select and install different thickness outboard spacers.

  20. Mount the special tools as shown in Fig 17. Locate the tip of special tool 308-021 on a flat surface on one of the bolts.
    21. NOTE: Repeat this step and the following step until the same reading appears on the indicator each time. Record the reading. This is the total differential bearing shim thickness required, less preload. The final calculation occurs later during assembly.

    26. NOTE: Use a feeler gauge or flat, clean drive pinion position shims as a measuring devise.
    NOTE: Do not attempt to force the gauge or shim between the special tools. A slight drag indicates a correct selection.
  26. Using a feeler gauge or flat, clean drive pinion position shims, measure between the special tools. Record the measurement. Refer to PINION RING GEAR VARIATION NUMBER  for shim selection information.
    • Remove the special tools after making the correct shim selection.

    27. CAUTION: Follow the drive pinion bearing preload shim and drive pinion position shim assembly sequence as directed or unit failure can result.
  27. Install the correct thickness drive pinion position shim on the pinion.
  28. If the pinion bearing preload is within specification and the pinion position shim has changed, change the drive pinion bearing preload shims by the same amount.
    • The direction arrow pointing toward the pinion flange indicates that by removing the drive pinion position shim, the distance from the centerline of the tubes to the pinion backface increases, giving a plus (+) reading. The drive pinion bearing preload shim pack does not affect the pinion depth setting. However, if the pinion position is changed, the pinion preload will change and may require adjustment to bring the torque-to-rotate within specification. Arrows on the ring gear illustrate the method to increase or decrease backlash and differential bearing preload.

    29. NOTE: Always use the same new inner pinion bearing installed when taking the measurement for drive pinion shim selection.
  29. Using the special tool and a suitable press, install the pinion bearing.
    • For semi-float axles, use tool 205-092.

    30. NOTE: Use the thickness of the old drive pinion bearing preload shims as a starting point for setting pinion bearing preload.
  30. Inspect the drive pinion bearing preload shims for damage. Discard them if necessary. New shims are available in the thickness shown in AVAILABLE DRIVE PINION BEARING PRELOAD SHIMS .

  40. Remove the master bearings from the differential case.
  41. Place one shim, of the necessary thickness, as determined from the previous measurement, on the LH side of the differential case. If additional shimming is necessary, beyond what the hardened differential bearing shim can provide, select and install a different thickness outboard spacer.

    G03883526Courtesy of FORD MOTOR CO.
  43. Determine the correct shim thickness and place it on the differential case hub on the RH side.
    • To determine the correct shim thickness, first, subtract the reading of the previous measurement from the total differential case end play reading. Then, add 0.25 mm (0.010 in) to this amount. This is the correct thickness shim to place on the hub. If additional shimming is necessary, beyond what the hardened differential bearing shim can provide, select and install a different thickness outboard spacer.
  44. Using the special tools, install the differential bearing.
    1. Place the special tool on the differential bearing to protect it during the installation of the opposite bearing.
    2. Using the special tool, drive the differential bearing onto the hub.

  45. Assemble the differential bearing cups to the differential bearings.
    46. CAUTION: Do not spread the differential housing more than specified.
    CAUTION: Avoid nicking the ring gear teeth and the anti-lock speed sensor ring during assembly.
  46. Using the special tools, spread the differential housing to the specification.
    • Use a rawhide hammer to seat the differential into the differential housing pocket.

      G04414224Courtesy of FORD MOTOR CO.
  48. Confirm the total preload.
    • Using an inch-pound torque wrench, check the torque to rotate the pinion. The reading must be higher than the initial reading (taken without the differential case installed) with new bearings installed as recommended by the following:
      • 3.54 and 3.73 = 0.9 Nm (8 lb-in)
      • 4.10 and 4.56 = 0.8 Nm (7 lb-in)
      • 4.63 and 5.13 = 0.8 Nm (7 lb-in)
    • If the total preload is too high, remove an equal amount of differential bearing shims from each differential case hub. If the total preload is too low, add an equal amount of differential bearing shims to each differential case hub.
