Differential Case and Ring Gear - Model 70, Limited Slip: 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.
- Remove the differential case. For additional information, refer to Differential Carrier - Dana 70 .
- Index-mark the differential case.
- Index-mark the differential case flange (ring gear) and button (cover) halves.
- Index-mark the differential pinion shafts and corresponding ramps.
- Remove the ring gear if required. For additional information, refer to Differential Ring And Pinion - Dana 70 .
- Loosen, but do not remove, the 8 bolts.
- Place the differential assembly on a bench.
- Remove the 8 bolts and the button half of the differential case.
- Remove the differential side gear, rear axle disc and plate kit, 4 differential pinion gears and the 2 differential pinion shafts. Keep these parts in order for correct installation by placing them aside with the button half of the differential case.
- Remove the rear axle disc and plate kit from the flange half of the differential case. Keep these parts in order.
- Inspect the following components:
- The clutch plates and clutch discs for cracks, excessive wear and distortion. Always install an entirely new rear axle disc and plate kit on both sides if discarding one or more of the clutch plates or clutch discs.
- The differential pinion shafts for excessive wear or pitting.
- The differential side gear and differential pinion gear teeth.
NOTE:
It is not necessary to remove the differential bearings to overhaul the limited-slip differential.
NOTE:
In most cases it is possible to disassemble the unit without removing the differential ring gear, which saves the cost of new bolts.
NOTE:
An axle shaft held in a vise, with the shaft splines extending not more than 76.2 mm (3 in) above the vise jaws, makes an excellent holding fixture for the differential case.
