Installation

1. Clean the pinion oil seal seat. Coat the sealing edge of the new seal with a small amount of Hypoid Gear Lubricant, C6AZ-1 9580-E (ESW-M2C105-A) or equivalent. Do not put sealer on the sealing lip. Drive the seal into the housing, using Tool T83T-4676-A for Econoline axles. Use Tool T8BT-4676-A for F-Super Duty Axles.

CAUTION: Installation without the proper tool may result in early seal failure. If seal becomes cocked during installation, remove it and install new one.




2. Coat the inside of the pinion flange with a small quantity of Hypoid Gear Lubricant, C6AZ-19580-E (ESW-M2C105-A) or equivalent, and install the flange on the pinion shaft, using Tool D81T-4858-A.

NOTE: The pinion flange must never be hammered on or installed with power tools.




3. Install the pinion attaching nut on the pinion shaft and tighten to specifications listed at the end of this Section. Hold the pinion flange with Tool T57T-4851-B while tightening the nut.




4. Connect the driveshaft to the axle pinion flange, secure with nuts and U-bolts or straps and bolts (F-Super Duty threaded flange) and tighten to specifications.

5. Raise the vehicle, remove the safety stands and then lower the vehicle to road position. Check the level of axle lubricant and add the specified lubricant as necessary.
