- Lubricate the axle universal joint flange splines and the pinion seal (3N134).
- Use Motorcraft SAE 75W-90 Premium 4x4 Front Axle Lubricant XY-75W90-TQL or equivalent meeting Ford specification WSP-M2C201-A.
- Align the index-marks and position the axle universal joint flange on the pinion shaft.
- Using the special tool, install the axle universal joint flange.
- Install the special tool, and tighten the pinion nut. Refer to Torque Specifications , used bearings.
- Rotate the pinion gear occasionally to make sure the pinion bearings are seating correctly. Take frequent pinion bearing torque preload readings by rotating the pinion gear with a Nm (inch/pound) torque wrench.
- If the preload recorded prior to disassembly is lower than the specification for used bearings, then tighten the pinion nut to the specification. If the preload recorded prior to disassembly is higher than the specification for used bearings, then tighten the pinion nut to the original reading as recorded.
- Align the index-marks then attach the front driveshaft. Refer to DRIVE SHAFTS - F150 for driveshaft fastener tightening specifications.
- Install the front differential support.
- Check and, if necessary, fill the differential.
