Differential Case and Ring Gear - Conventional: Assembly

WARNING: This page is about a different car, the 2011 Ford Pickup and 2011 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

Place the differential case in a vise.
NOTE: Use a vise with brass jaws or wood blocks.
Lubricate and assemble both differential side gears and differential side gear thrust washers. Hold them in place. Then, lubricate and assemble the differential pinion gears with the differential pinion gear thrust washers to hold the differential side gears in place.
NOTE: The best way to assemble the differential side gears and the differential pinion gears is to lubricate all parts with the specified rear axle lubricant.

Using a suitable tool, line up the holes with those of the differential case.
NOTE: Rotate the differential side gears until the holes of the differential pinion gear thrust washers and the differential pinion gears line up with the holes of the differential case. If the differential pinion gears will not rotate by hand, install one of the axle shafts into the spline of the differential side gear and use a pipe wrench to turn the axle shaft.
Position the differential pinion shaft. Align the lockpin hole in the differential pinion shaft with the lockpin hole in the differential case.
Assemble the differential pinion shaft lockpin. Peen the metal of the differential case over the differential pinion shaft lockpin in 2 places, 180 degrees apart, to lock it in place. Note the location of the slot in the differential pinion shaft lockpin and peen it 90 degrees apart.

Start 2 new ring gear bolts through the differential case flange, the anti-lock sensor ring and into the differential ring gear to make sure the differential ring gear and the differential case align.
NOTE: If removed, install the anti-lock speed sensor ring.

Press the differential ring gear on the differential case. The differential case flange acts as a pilot for the anti-lock speed sensor ring.

Install the 10 remaining ring gear bolts alternately and evenly.
- Tighten the new bolts to 298 Nm (220 lb-ft).

Using the Differential Carrier Bearing Step Plate and Differential Carrier Bearing Installer, install the differential bearing.
1. Place the Differential Carrier Bearing Step Plate on the differential bearing to protect it during the installation of the opposite bearing.
2. Using the Differential Carrier Bearing Installer, drive the differential bearing onto the hub.
