Differential Ring and Pinion

Differential Ring And Pinion

























Removal

All vehicles

1. Remove the drive pinion flange seal. For additional information, refer to Drive Pinion Flange and Drive Pinion Seal Rear Drive Axle/Differential - Ford 9.75-Inch Ring Gear.

2. Remove the differential carrier assembly. For additional information, refer to Differential Carrier Differential Carrier.

3. Remove and discard the 12 ring gear bolts.





4. NOTE: Do not damage the ring gear bolt hole threads.

Insert a punch in the ring gear bolt holes and drive the differential ring gear off.





Electronic Locking Differential (ELD) equipped vehicles

5. Using the Bearing Puller plate, Step Plate and a suitable press, remove the LH differential bearing.





6. Using the 2 Jaw Puller and Step Plate, remove the RH differential bearing.





Non-ELD equipped vehicles

7. Remove the 2 differential bearings with the 2 Jaw Puller and Step Plate.





All Vehicles

8. Remove the drive pinion shaft oil slinger.





9. Install the Drive Pinion Thread Protector, then use a soft-faced hammer to drive the pinion gear out of the outer drive pinion bearing and remove the pinion gear.





10. Remove and discard the drive pinion collapsible spacer.





11. Using a brass drift, remove the 2 drive pinion bearing cups by tapping alternately on opposite sides of the 2 drive pinion bearing cups.





Installation

All vehicles

1. Position the Drive Pinion Bearing Cup Installer and the inner and outer drive pinion bearing cups in their respective bores.

1. Place the Rear Axle Pinion Bearing Cup Installer on the outer drive pinion bearing cup.

2. Place the Rear Axle Pinion Bearing Cup Installer on the inner drive pinion bearing cup.

3. Install the Drive Pinion Bearing Cup Installer.





2. Tighten the Drive Pinion Bearing Cup Installer to fully seat the 2 differential drive pinion bearing cups.





3. NOTE: If a feeler gauge of the specification shown can be inserted between a cup and the bottom of its bore at any point around the cup, the cup is not correctly seated.

Make sure the differential pinion bearing cups are correctly seated.





4. NOTICE: Use the same drive pinion bearings and the drive pinion bearing adjustment shim from the drive pinion bearing adjustment shim selection procedure for final assembly or damage to the component may occur.

NOTE: Install new drive pinion bearings without any additional lubricant since the anti-rust oil provides adequate lubricant without upsetting the drive pinion bearing preload settings.

Install the new drive pinion bearings and Adapters as shown.









5. Tighten the Adapter to the specified rotational torque.
- Tighten to 2.2 Nm (20 lb-in).





6. NOTE: The Adapter must be offset to obtain an accurate reading.

Rotate the Adapter several half-turns to make sure of correct seating of the drive pinion bearings.





7. Install the Drive Pinion Gauge Tube.

1. Position the Drive Pinion Gauge Tube.

2. Install the 2 differential bearing caps.

3. Install the 4 differential bearing cap bolts.
- Tighten to 105 Nm (77 lb-ft).





8. NOTE: Drive pinion bearing adjustment shims must be flat and clean.

NOTE: A slight drag should be felt for correct drive pinion bearing adjustment shim selection. Do not attempt to force the drive pinion bearing adjustment shim between the gauge block and the gauge tube. This will minimize selection of a drive pinion bearing adjustment shim thicker than required, which results in a deep tooth contact in the final assembly of integral axle assemblies.

Use a drive pinion bearing adjustment shim as a gauge for drive pinion bearing adjustment shim selection.

- After the correct drive pinion bearing adjustment shim thickness has been determined, remove the Adapters.





9. Using the Bearing/Oil Seal Plate and Drive Pinion Bearing Cone Installer, press the drive pinion bearing and selected drive pinion bearing adjustment shim until they are firmly seated on the pinion gear.





10. Place a new drive pinion collapsible spacer on the pinion gear against the pinion gear shoulder.





11. Install the outer drive pinion bearing and drive pinion shaft oil slinger.





12. Lubricate the pinion flange splines with grease.

13. Install the pinion gear in the pinion gear bore from inside the axle housing.





14. Using the Differential Carrier Bearing Installer, press the LH and RH differential bearing on the differential assembly.





SVT vehicles

15. NOTE: The differential flange and ring gear flange must be free of any old retaining compound material. Make sure both surfaces are clean and free of oil, dust and debris. Failure to clean the surfaces can result in ring gear runout concerns.

Clean all traces of the old retaining compound material from the differential flange.

- Use solvent and Scotch-Brite(R) pads to remove.

16. Apply a one-eighth inch bead of maximum strength retaining compound on the rear face of the ring gear in the pattern shown.





All vehicles

17. NOTE: If removed, press the speed sensor ring on with the differential ring gear.

Install the differential ring gear.

1. Place the differential ring gear on the differential assembly.

2. Hand-start 3 new ring gear bolts to align the holes in the differential ring gear and the differential assembly.

3. Place the differential assembly and differential ring gear onto the press bed blocks with the differential ring gear teeth facing downward.

4. Press the differential ring gear into place.





18. Install the remaining 9 new differential ring gear bolts.
- Tighten to 150 Nm (111 lb-ft).





19. Install the drive pinion seal and flange. For additional information, refer to Drive Pinion Flange and Drive Pinion Seal Rear Drive Axle/Differential - Ford 9.75-Inch Ring Gear.

20. Install the differential carrier. For additional information, refer to Differential Carrier Differential Carrier.
