Differential Case and Ring Gear - Conventional: Disassembly

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.

NOTE: Differential bearing shims are available in thicknesses of 0.762, 0.787, 0.813, 0.838, 0.864, 0.889 and 0.914 mm (0.030, 0.031, 0.032, 0.033, 0.034, 0.035 and 0.036 in).

NOTE: If differential bearing shims are damaged, install new ones.

NOTE: Install new differential bearings whenever they are removed from the rear axle differential carrier.

Using the special tools, remove the differential bearings.
- Wire the differential bearing shims, differential bearing cup, differential bearing and outboard selective spacer together. Note from which side they were removed (ring gear side or opposite side).

NOTE: Use a vise with brass jaws or wood blocks.

Place the differential case in a vise.

CAUTION: Do not damage the anti-lock speed sensor ring when removing the ring gear. If the anti-lock speed sensor ring is removed, a new one must be installed.

NOTE: Whenever removing the ring gear bolts, always install new bolts upon assembly. Use grade 9 bolts for service replacement for all Dana rear axles.

Remove the bolts on the ring gear. Leave four bolts loosely assembled, 90 degrees apart.
Tap each bolt head alternately with a rawhide or plastic hammer to loosen the ring gear. Remove the bolts and the ring gear.

Place the differential case in a vise. Using a small drift, drive out the differential pinion shaft lock pin that secures the differential pinion shaft.
Using a drift, remove the differential pinion shaft.
