Drive Pinion Flange and Seal: Installation
WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
- Install a new collapsible spacer.
- Install the outer pinion bearing and the drive pinion oil slinger.
- Using the special tool, install the drive pinion oil seal.
- Align the index marks and using the special tool, install the pinion flange.
- Install the new washer and pinion nut. Only hand-tighten the pinion nut at this time.
- Using the special tool to hold the pinion flange, tighten the pinion nut to set the pinion bearing preload.
- Tighten the pinion nut, rotating the pinion occasionally to make sure the pinion bearings are seating correctly. Take frequent pinion bearing preload readings by rotating the pinion gear with a Nm torque wrench. The final reading must be 0.56 Nm (5 lb-in) more than the initial reading taken during removal.
- Install the disc brake caliper and disc brake caliper anchor as an assembly, then the disc brake caliper anchor bolts.
- Tighten to 108 Nm (80 lb-ft).
- Install the front driveshaft. For additional information, refer to DRIVESHAFT .
- Install the front tires and wheels. For additional information, refer to WHEELS AND TIRES .
NOTE:
Lubricate the drive pinion oil seal lips with axle lubricant.
NOTE:
Drive pinion oil seal must be fully seated all the way around or drive pinion oil seal damage will occur.
CAUTION:
Never use a hammer or install the pinion flange with power tools.
NOTE:
Lubricate the pinion flange splines with axle lubricant.
CAUTION:
Do not loosen the pinion nut to reduce pinion bearing preload. Install a new collapsible spacer and pinion nut if pinion bearing preload reduction is necessary.
CAUTION:
Always connect the front driveshaft to the axle first. Otherwise, the weight of the driveshaft can pinch the boot between the shaft and the flange and cause the boot to tear.
CAUTION:
Install the driveshaft with new bolts and washers and new bolts and universal joint retainers. If new bolts are not available, coat the threads of the original bolts with threadlock and sealer.
