Ring Gear and Pinion Backlash

WARNING: This page is about a different car, the 2004 Ford Pickup and 2004 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
  1. Install the outboard spacers in the side from which they were removed.

  2. Place the differential assembly with the special tool in the differential housing.

  3. Install the special tools. Locate the tip of the Clutch Housing Gauge on a flat surface of one of the bolts.

    4. NOTE: Repeat this step and the following step until the same reading appears on the indicator each time. This is the differential bearing shim thickness necessary between the differential case and the differential bearing on the differential ring gear side of the differential case.

  4. Force the differential case (differential ring gear) away from the drive pinion. With force still applied, set the indicator at 0.
  5. Force the differential ring gear into mesh with the pinion, to obtain an indicator reading. Record the reading.

  6. Remove the special tools and the differential case from the differential housing.
  7. Remove the Master Bearings from the differential case.
  8. Place one shim, of the necessary thickness as determined from the previous measurement, on the differential ring gear 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.
  9. Using the special tool, install the differential bearing on the differential ring gear side of the differential case.

  10. Determine the correct shim thickness, and place the shim on differential case hub on the drive pinion side.
    • To determine the correct shim thickness, first subtract the reading of the previous measurement from the total differential case end play reading obtained under DIFFERENTIAL CASE END PLAY CHECK . 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.
  11. 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.
