Differential Case and Ring Gear - Model 60, 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.
- Soak the clutch packs for 20 minutes in friction modifier.
- Pre-lubricate the differential side gear thrust faces and assemble the clutch plates and clutch discs onto the differential side gears.
- Pre-lubricate each component of both stacks with rear axle lubricant or with friction modifier.
- Assemble the retainer clips to the clutch plate ears. Both clips must seat completely onto the clutch plate ears.
- Install the rear axle disc and plate kit and differential side gear in the differential case.
- The rear axle disc and plate kit must stay assembled to the differential side gear splines. The retainer clips must seat completely in the differential case pocket.
- Install the bottom differential clutch pack and differential side gear in the differential case.
- The rear axle disc and plate kit must stay assembled to the differential side gear splines. The retainer clips must seat completely in the differential case pocket.
- Install the Step Plate.
- Apply a small amount of grease to the centering hole of the Step Plate.
- Screw the Limited Slip Preload Tool into the step plate.
- Position the differential case onto the holding fixture.
- Position both differential pinion gears opposite one another in the differential case. Align the differential pinion gear holes with each other. Hold the differential pinion gears in place by hand.
- Tighten the Limited Slip Preload Tool enough so that the differential side gears move away from the differential pinion gears and relieve the loaded condition.
- While holding the differential pinion gears in place, insert the Rotating Handle into the differential pinion shaft bore. Rotate the differential case until the holes of both differential pinion gears align with those in the differential case.
- Tighten the Limited Slip Preload Tool enough to allow clearance to assemble the differential pinion thrust washers.
- Assemble the differential pinion gear thrust washers into the differential case.
- Use a very small screwdriver to push the washers into place.
- Remove all the tools from the differential case.
- Install the differential pinion shaft.
- Install the differential pinion shaft lock pin.
- If removed, install the differential ring gear.
- Tighten the 12 Grade 9 bolts to 176 N.m (130 lb-ft).
NOTE:
Always install an entirely new stack of clutch plates and discs on both sides if discarding one or more of the clutch plates or clutch discs or damage to the component may occur.
NOTE:
Assemble the rear axle disc and plate kits to the differential side gears in exactly the same order as removed or damage to the component may occur.
NOTE:
Hold the rear axle disc and plate kit to keep it from falling out of the differential case.
NOTE:
Slightly loosen or tighten the Limited Slip Preload Tool to apply the necessary load to allow the differential side gears and differential pinion gears to rotate.
NOTE:
Do not overtighten the Limited Slip Preload Tool. Overtightening can damage the rear axle disc and plate kit.
NOTE:
During assembly, the differential pinion thrust washer and the differential pinion gear holes must align exactly with those in the differential case.
