Differential Case and Ring Gear - Conventional: Disassembly
WARNING: This page is about a different car, the 2008 Ford RV Cutaway, 2008 Ford Econoline, 2008 Ford E450 Super Duty, and 2008 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
All axles
- Remove the differential carrier. For additional information, refer to Differential Carrier - Dana 60 or Differential Carrier - Dana 70 .
- Using the Drive Pinion/Differential Carrier Puller, 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).
- Place the differential case in a vise.
- Remove the bolts on the ring gear. Leave 4 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.
- Remove the differential pinion shaft lock screw.
- Using a drift, remove the differential pinion shaft.
- To remove the differential side gears and the differential pinion gears, rotate the differential side gears. The differential pinion gears will turn to the opening of the differential case.
- Remove the differential pinion gears and the differential pinion gear thrust washers behind the differential pinion gears.
- Lift out the differential side gears and the differential side gear thrust washers.
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.
NOTE:
Use a vise with brass jaws or wood blocks.
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.
Full-float axles
NOTE:
Use a vise with brass jaws or wood blocks.

Semi-float axles
NOTE:
The semi-float axle differential assembly is equipped with either a Loctite® coated differential pinion shaft lock screw or a differential pinion shaft lock screw with torque prevailing threads. The Loctite® treated differential pinion shaft lock screw has a 5/32-in hexagram socket head. Never, under any circumstance, reuse a Loctite® coated screw after removing it. Always discard the screw and install a new one. The torque prevailing differential pinion shaft lock screw has a 12-point drive head. This type of screw is reusable for no more than 4 installations. When in doubt of the number of installations of a torque prevailing differential pinion shaft lock screw, discard it and install a new one or damage to the component may occur.
