Differential Case and Ring Gear - Traction-Lok®: Assembly

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. Prelubricate each steel clutch plate and soak all friction plates with 118 ml (4 ounces) of friction modifier for at least 15 minutes.

  2. NOTE: Do not mix the differential clutch packs or shims from one side with the other.
    NOTE: The Belleville spring is a dished plate.

  3. Assemble the differential clutch packs (without the shims and Belleville springs) on the respective differential side gears.
  4. Clamp the bolt head of the special tool in a vise. Install the differential clutch pack and the differential side gear (without the shim or the Belleville spring) on the gauge.

  10. Place the shim and Belleville spring on the differential clutch pack.
    • The dished or concave side of the Belleville spring must face up and against the thrust face of the differential case.
      • Refer to the exploded view in the DESCRIPTION AND OPERATION .

  11. Insert the differential clutch packs with shims and Belleville springs and differential side gears into the differential case.
    • Hold the upper clutch pack and side gear assembly in place to prevent it from falling out of the differential case.

  12. NOTE: Apply a small amount of grease to the step plate bore.
    NOTE: If necessary, insert the dowel bar in the nut bore to keep the nut from turning as the hex screw is tightened.
  13. Assemble the special tool to the differential case.
    1. Position the step plate in the bottom side gear bore.
    2. Position the nut in the top side gear bore and hold it in place.
    3. Install the hex-head screw and tighten it two turns after it contacts the bottom step plate.

  14. NOTE: Prelubricate both sides of the differential pinion thrust washers with rear axle lubricant.
    NOTE: Make sure the differential pinion gears are 180 degrees apart so they will align correctly with the pinion shaft bore.

  15. Position the differential pinion gears and differential pinion thrust washers in the window of the differential case so they mesh with the differential side gear teeth.
  16. WARNING: Keep fingers and hands away from pinion gears when rotating the differential case with the differential rotating tool.
    NOTE: It may be necessary to loosen or tighten the forcing screw to allow the differential pinion gears and differential side gears to rotate.

  17. Insert the special tool into the pinion shaft bore and turn the differential case. This will cause the differential pinion gears to engage the differential side gears and "walk" into the differential case. Rotate the differential case until the pinion mating shaft holes are lined up exactly with the holes in the differential pinion gears.
  18. Loosen the forcing screw and remove the step plate and nut from the side gear bores. Install the differential pinion shaft in the differential case.
    • Install a new differential pinion shaft lock bolt finger-tight.

  19. Install new differential bearings, if removed.

  20. Check the torque required to rotate one differential side gear.
    • Mount the differential case and the Traction-Lok Torque Tool Set in a vise.
    • The initial break-away torque, if original clutch plates are used, must be within specification. The rotating torque required to keep the differential side gear turning with new clutch plates can vary.

  21. CAUTION: Make sure that the notches on the case flange and the anti-lock speed sensor ring are aligned.
  22. Install the ring gear and, if removed, a new anti-lock speed sensor ring on the differential case and tighten the bolts.
    • Apply sealer to the ring gear bolts before installation.
