Removing & Installing

WARNING: This page is about a different car, the 2005 Ford RV Cutaway, 2005 Ford Econoline, 2005 Ford E450 Super Duty, and 2005 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
  1. Raise the vehicle on a hoist or raise the rear end of the vehicle with a jack. Install safety stands under the frame rails and lower the jack or hoist enough to allow the rear axle to drop into the rebound position for working clearance. For additional information, refer to JACKING & LIFTING .
  2. Remove the differential housing cover and drain the lubricant.
    • Clean the gasket material from the differential housing cover and the differential housing.
  3. Remove the axle shafts. For additional information, refer to AXLE SHAFT - SEMI-FLOATING AXLE .
    4. CAUTION: Note the positions of the mating letters stamped vertically and horizontally on the bearing caps and the differential housing before removing the bearing caps. Matching the letters is important at the time of assembly.

  4. To ease removal of the differential assembly, loosen the bolts, then pry the differential case, bearing cups and outboard spacers outward until they are loose in the differential housing.
  5. Remove the bolts and the bearing caps.
    6. CAUTION: Do not spread the differential housing more than specified.

  6. Using the special tools, spread the differential housing to the specification. Remove special tool 100-D002 after spreading the housing.
    7. CAUTION: It will be necessary to use large pry bars to remove the differential assembly from the differential housing. Do not damage the differential ring rear when carrying out this step.
    CAUTION: Mark or tag the differential bearing cups, indicating from which side they were removed.
  7. Remove the differential assembly with the bearing cups.
    • Inspect the differential bearing cups for deep scores, galling and spalling. Discard them if necessary.

    8. CAUTION: Mark or tag the outboard spacers indicating from which side they were removed.
  8. Remove the outboard spacers.
    • Inspect the spacers for nicks, bending and grooved conditions. Discard them if necessary.

  9. Assemble the differential bearing cups to the differential bearings.
    10. CAUTION: Mark or tag the outboard spacers indicating from which side they were removed.

  10. Install the outboard spacers in their original positions.
    11. 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.
  11. Using the special tools, spread the differential housing to the specification.
    • Use a rawhide hammer to seat the differential into the differential housing pocket.
      • Remove the special tools.

  12. Install the bearing caps, aligning the letters with those on the differential housing. Tighten the bolts to specification.
  13. Using the special tools, measure the differential ring gear and pinion backlash at three equally spaced points.

  14. Carry out the Tooth Contact Pattern Check to verify the final pinion position is correct. For additional information, refer to CHECKING TOOTH CONTACT PATTERN AND CONDITION OF THE RING AND PINION .
  15. Install the axle shafts. For additional information, refer to AXLE SHAFT - SEMI-FLOATING AXLE .
    16. CAUTION: Clean both flat surfaces (differential housing and differential housing cover) with a suitable solvent to remove all traces of oil film.
    CAUTION: Install the differential housing cover within 15 minutes of applying the silicone, or it will be necessary to apply new sealant.
    NOTE: The differential housing cover uses silicone rubber sealant as a gasket.

  16. Apply a continuous bead of silicone sealant, of the specified thickness, to the differential housing cover.
  17. Place two bolts into the differential housing cover at the 8 o'clock and 2 o'clock positions. Install the differential housing cover.
    • Use the two bolts to position the differential housing cover on the differential housing.
  18. Install the remaining bolts. Tighten the bolts alternately and evenly.
    • Tighten Grade 5 bolts to 47 Nm (35 lb-ft).
    • Tighten Grade 8 bolts to 61 Nm (45 lb-ft).
    • Allow 1-hour cure time before filling the axle with the correct amount of specified lubricant.
