Differential Case and Ring Gear - Traction-Lok: Assembly
WARNING: This page is about a different car, the 2003 Ford RV Cutaway, 2003 Ford Econoline, 2003 Ford E550 Super Duty, 2003 Ford E450 Super Duty, and 2003 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
- Prelubricate each steel clutch plate and soak all friction plates with Additive Friction Modifier C8AZ-19B546-A or equivalent meeting Ford specification EST-M2C118-A for at least 15 minutes.
- Assemble the differential clutch packs (without the shims) on the respective differential side gears.
- Place the base portion of the special tool in a vise. Install the differential clutch pack and differential side gear (without the shim) on the gauge.
- Position the special tool hand-tight on top of the differential clutch pack.
- Install the special tool over the disc and differential clutch pack.
- Install the nut of the gauge over the top and base stud.
- Select the thickest blade of a suitable feeler gauge that will enter between the tool and the differential clutch pack. The reading will be the thickness of the new clutch shim.
- Remove the special tool from the clutch pack and side gear assembly.
- Install shims on the clutch pack and side gear assembly.
- Install the differential side gear in the differential case.
- Install the differential pinion gears with differential pinion thrust washers in the differential case.
- Install the differential clutch spring, using a soft-faced hammer.
- Install the differential pinion shaft and install a new differential pinion shaft lock bolt finger-tight.
- Using the special tool, install the differential bearing on the differential case. Repeat for the other side.
- Install the anti-lock speed sensor ring by aligning the tab on the anti-lock speed sensor ring with the slot on the differential case.
- Start two of the ring gear bolts through the differential case and into the ring gear to make sure the ring gear bolt holes align with the differential case bolt holes correctly.
- Press the new anti-lock speed sensor ring and the ring gear on the differential case.
- Install the ring gear bolts.
- Apply Stud and Bearing Mount EOAZ-19554-BA or equivalent meeting Ford specification WSK-M2G349-A1 to the ring gear bolts.
- Check the torque required to rotate one differential side gear.
- Mount the differential case and special tool in a vise.
- The initial minimum break-away torque, if original clutch plates are used, must be within specification. The minimum rotating torque required to keep the differential side gear turning with new clutch plates may vary.
- For additional information, refer to DRIVELINE SYSTEM-GENERAL INFORMATION .
- Install the differential case. For additional information, refer to DIFFERENTIAL CASE .
CAUTION:
118 ml (4 oz) of the specified Additive Friction Modifier must be used in the axle.

CAUTION:
Do not mix the differential clutch packs or shims from one side with the other.
CAUTION:
Select the correct mandrel to use with the Traction-Lok Differential Gauge.
CAUTION:
Make sure that the notches on the case flange and the anti-lock speed sensor ring are aligned.
