WARNING: This page is about a different car, the 2004 Ford RV Cutaway, 2004 Ford Econoline, 2004 Ford E450 Super Duty, and 2004 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
- Remove the lock screw and the differential pinion shaft.
- Push the axle shaft into the axle tube and engage the differential side gear with the shaft splines.
- Push the axle shaft toward the center of the axle and install the U-washer. Pull the axle shaft outward until the U-washer locks into the differential side gear.
- Align the differential pinion shaft lock screw hole with the hole in the differential case. Correctly position the differential pinion thrust washers. Install the differential pinion shaft.
- Install the new lock screw.
- Apply a continuous bead of silicone sealant to the differential housing cover mounting surface.
- Assemble two bolts into the differential housing cover at the eight o'clock and two o'clock positions. Using the two bolts as a guide, position the differential housing cover on the differential housing.
- 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).
- Fill the differential housing with 3.0L (6.3 pints) of the specified rear axle lubricant. For additional information, refer to SPECIFICATIONS .
- Install the brake disc. For additional information, refer to DISC & DRUM .
- Install the wheel and tire assembly. For additional information, refer to WHEELS & TIRES .
- Lower the vehicle.
CAUTION:
Do not damage the wheel bearing oil seal when installing the axle shaft.
NOTE:
The threads in the differential case and on the lock screw must be free of dirt and oil.
CAUTION:
Clean the mounting surface on the differential housing cover and the differential housing with a suitable solvent to remove all traces of oil film.
CAUTION:
The differential housing cover uses silicone rubber sealant material as a gasket. Install the differential housing cover within 15 minutes of applying the silicone or it will be necessary to apply new sealant.
