Drive Pinion Seal: Installation
WARNING: This page is about a different car, the 2002 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
- Verify that the splines on the pinion stem are free of burrs. If burrs are evident, remove them with a fine crocus cloth. Work in a rotating motion to wipe the pinion clean.
- Clean the pinion seal bore.
- Install a new collapsible spacer.
- Install the original differential pinion bearing and the front axle drive pinion shaft oil slinger.
- Lubricate the pinion seal.
- Using the special tool, install the pinion seal.
- Lubricate the pinion flange splines.
- Align the index marks and install the pinion flange.
- Install the new nut hand-tight.
- Use the special tool to hold the pinion flange while tightening the nut to set the preload.
- Tighten the nut, rotating the pinion occasionally to ensure the differential pinion bearings are seating correctly. Take frequent differential pinion bearing preload readings by rotating the pinion with a Nm (inch-pound) torque wrench. The final reading must be 0.56 Nm (5 lb-in) more than the initial reading taken during removal.
- Align the index marks and position the front driveshaft.
- Install the universal joint spider retainers and bolts.
- Check the fluid level and, if necessary, fill the axle to specification with lubricant.
- Install the caliper and anchor plate assembly.
- Install the wheel and tire assembly. For additional information, refer to WHEELS & TIRES .
- Lower the vehicle.
NOTE:
Pinion seal must be fully seated all the way around or pinion seal damage will occur.
CAUTION:
Never use a metal hammer on the pinion flange or install the flange with power tools. If necessary, use a plastic hammer to tap on a tight fitting flange.
CAUTION:
Do not loosen the nut to reduce preload. Install a new collapsible spacer and nut if preload reduction is necessary.
