Drive Pinion Flange and Drive Pinion Seal: Installation
WARNING: This page is about a different car, the 2006 Ford Pickup and 2006 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
- Lubricate the new pinion seal with clean premium long-life grease.
- Using the special tool, install a new rear axle drive pinion seal.
- Lubricate the pinion flange splines with clean synthetic rear axle lubricant.
- Align the pinion flange with the drive pinion shaft.
- With the pinion flange in place in the rear axle housing, use the special tool to install the pinion flange.
- Position the new pinion nut.
- Use the special tool to hold the pinion flange while tightening the pinion nut.
- Tighten the pinion nut, rotating the pinion occasionally to make sure the cone and roller bearings are seating correctly. Take frequent cone and roller bearing torque preload readings until the original recorded preload reading is obtained by rotating the pinion with a Nm torque wrench.
- If the original recorded preload is lower than specifications, tighten to the appropriate specification for used bearings. If the preload is higher than specification, tighten the nut to the original reading as recorded. Refer to TORQUE SPECIFICATIONS .
- Install the driveshaft. For additional information, refer to DRIVESHAFT .
- Install the brake calipers. For additional information, refer to REAR DISC BRAKE .
CAUTION:
If the rear axle drive pinion seal becomes misaligned during installation, remove the rear axle drive pinion seal and replace it with a new seal.
NOTE:
Disregard the scribe marks if a new pinion flange is being installed.
CAUTION:
Under no circumstances is the pinion nut to be backed off to reduce preload. If reduced preload is required, a new collapsible spacer and pinion nut must be installed.
