Differential Case and Ring Gear - Model 70, Limited Slip: Assembly
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.
- Coat the rear axle disc and plate kit with rear axle lubricant.
- Install the rear axle disc and plate kit and the side gear in the flange half of the differential case.
Item Part Number Description 1 4236 Differential side gear 2 - Preload spacer (part of 4880) 3 - Clutch plates (part of 4880) 4 - Clutch friction discs (part of 4880) - Align the clutch pressure plate lugs, and install the side gear, the clutch pack and differential side gear in the button half of the differential case.
- Place the differential pinion shaft and 2 differential pinion gears in the button half of the differential case.
- Install the other differential pinion shaft and 2 differential pinion gears in the flange half of the differential case.
- Assemble the differential case.
- Place the button half of the differential case onto the flange half of the differential case assembly.
- Install the 8 bolts. Turn each one in a few threads.
- Tighten the bolts evenly and alternately.
- Tighten to 129 Nm (95 lb-ft).
NOTE: The bolts must be clean and dry or damage to the component may occur. - Install the ring gear if removed. For additional information, refer to Differential Ring And Pinion - Dana 70 .
- Install the differential case. For additional information, refer to Differential Carrier - Dana 70 .
NOTE:
After assembly, make sure that the side gear splines engage the clutch pack splines and the differential side gear is fully seated or damage to the component may occur.
NOTE:
For vehicles operating at close to their GVW rating, typically emergency vehicles and vehicles equipped with a fifth wheel, there may be circumstances of continuing chatter/bumping in turns despite the installation of new parts and lubricant. In cases such as this, it is permissible to reassemble the rear axle disc and plate kit with the clutch disc adjacent to the differential side gear, resulting in 2 clutch plates together. This results in 3 friction surfaces instead of the normal 5, lowering the torque to rotate the wheel by 40%.
NOTE:
Align the index marks made during disassembly or damage to the component may occur.
