Differential Case: Removal

WARNING: This page is about a different car, the 2010 Ford Pickup and 2010 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to JACKING & LIFTING .
Remove the 10 bolts and the differential housing cover.
- Drain the lubricant from the rear axle.
Clean the gasket material from the differential housing cover and the differential housing.
Remove the axle shafts. For additional information, refer to WHEEL HUBS AND BEARINGS - FULL FLOATING AXLE - DANA .

NOTE: Note the positions of the mating letters stamped vertically and horizontally on the bearing caps and the differential housing before removing the bearing caps.

Using the Differential Carrier Spreader and Dial Indicator Gauge with Holding Fixture, spread the differential housing.

NOTE: It will be necessary to use large pry bars to remove the differential assembly from the differential housing. Do not damage the differential ring gear when carrying out this step.

NOTE: Mark or tag the differential bearing cups, indicating from which side they were removed.

Remove the differential assembly with the bearing cups.
- Inspect the differential bearing cups for deep scores, galling and spalling.

NOTE: If damaged, install new differential bearing shims.

NOTE: Install new differential bearings and cups if removing the bearings from the differential case.

Using the Differential Carrier Bearing Collets, Bearing Tube Removal Screw, Bearing Tube Remover, Differential Carrier Bearing Step Plate and Differential Carrier Bearing Retaining Ring, remove the differential bearings.
- Tag the selective inboard spacers to identify the side from which they were removed.
