Companion Flange Replacer
TOOL-4858-E or equivalent
Differential Side Bearing Puller

Removal

  1. NOTE: The rear wheels and disc brake rotors must be removed to prevent brake drag during drive pinion bearing preload adjustment.

    Remove the rear disc brake rotors
  2. NOTE: If the companion flange is being replaced, it is not necessary to mark the driveshaft flange.
  3. Mark the driveshaft flange and rear axle companion flange for correct alignment during installation.

4. Remove the four rear driveshaft bolts and disconnect the driveshaft. Wire the driveshaft aside.

5. Install an inch-pound torque wrench on the pinion nut and record the torque required to maintain rotation of the pinion through several revolutions.

6. Use (B) Companion Flange Holding Tool to hold the (A) rear axle companion flange while removing the (C) pinion nut.

7. Mark the (A) driveshaft rear axle companion flange in relation to the (B) drive pinion stem for proper alignment during installation.

8. Use Differential Side Bearing Puller to remove the rear axle companion flange.

 

Installation

  1. Lubricate the rear axle companion flange splines.
    • Use Motorcraft Synthetic Rear Axle Lubricant F1TZ-19580-B or equivalent meeting Ford specification WSL-M2C192-ANOTE: Disregard the scribe marks if a new rear axle companion flange is being installed.
  2. Align the (A) rear axle companion flange with the (B) drive pinion shaft.

 

3. Use Companion Flange Replacer to install rear axle companion flange.

4. Position the new pinion nut.

5. Use (B) Companion Flange Holding Tool to hold the (A) rear axle companion flange while tightening the (C) pinion nut.

  • Tighten the pinion nut, rotating the pinion occasionally to make sure the cone and roller bearings are seated properly. Take frequent pinion bearing torque preload readings until the original recorded preload reading is obtained by rotating the pinion with a Nm (inch-pound) torque wrench.
  • If the original recorded preload is lower than specification, tighten to specification. If the preload is higher than specification, tighten to original reading as recorded.

6. Remove the Companion Flange Holding Tool.
