Differential Ring And Pinion: Installation
WARNING: This page is about a different car, the 2012 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
All vehicles
- Position the Drive Pinion Bearing Cup Installer and the inner and outer drive pinion bearing cups in their respective bores.
- Place the Rear Axle Pinion Bearing Cup Installer on the outer drive pinion bearing cup.
- Place the Rear Axle Pinion Bearing Cup Installer on the inner drive pinion bearing cup.
- Install the Drive Pinion Bearing Cup Installer.
- Tighten the Drive Pinion Bearing Cup Installer to fully seat the 2 differential drive pinion bearing cups.
- Make sure the differential pinion bearing cups are correctly seated.
- Install the new drive pinion bearings and Adapters as shown in illustration.
- Tighten the Adapter to the specified rotational torque.
- Tighten to 2.2 Nm (20 lb-in).
- Rotate the Adapter several half-turns to make sure of correct seating of the drive pinion bearings.
- Install the Drive Pinion Gauge Tube.
- Position the Drive Pinion Gauge Tube.
- Install the 2 differential bearing caps.
- Install the 4 differential bearing cap bolts.
- Tighten to 105 Nm (77 lb-ft).
- 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.
- 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.
- Place a new drive pinion collapsible spacer on the pinion gear against the pinion gear shoulder.
- Install the outer drive pinion bearing and drive pinion shaft oil slinger.
- Lubricate the pinion flange splines with grease.
- Install the pinion gear in the pinion gear bore from inside the axle housing.
- Using the Differential Carrier Bearing Installer, press the LH and RH differential bearing on the differential assembly.
Electronic Locking Differential (ELD) equipped vehicles and all vehicles equipped with 3.55, 3.73, and 4.10 ratio gear sets
- Clean all traces of the old retaining compound material from the differential flange.
- Use solvent and Scotch-Brite® pads to remove.
- Apply a one-eighth inch bead of maximum strength retaining compound on the rear face of the ring gear in the pattern shown in illustration.Fig 14: Identifying Bead Of Maximum Strength Retaining Compound Applying Area On Rear Face Of Ring Gear

All vehicles
- Install the differential ring gear.
- Place the differential ring gear on the differential assembly.
- Hand-start 3 new ring gear bolts to align the holes in the differential ring gear and the differential assembly.
- Place the differential assembly and differential ring gear onto the press bed blocks with the differential ring gear teeth facing downward.
- Press the differential ring gear into place.
- Install the remaining 9 new differential ring gear bolts.
- Tighten to 150 Nm (111 lb-ft).
- Install the drive pinion seal and flange. For additional information, refer to DRIVE PINION FLANGE AND DRIVE PINION SEAL .
- Install the differential carrier. For additional information, refer to DIFFERENTIAL CARRIER .
NOTE:
If a feeler gauge of the specification shown in illustration can be inserted between a cup and the bottom of its bore at any point around the cup, the cup is not correctly seated.
NOTE:
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.
| Item | Part Number | Description |
|---|---|---|
| 1 | 4621 | Outer pinion bearing |
| 2 | 205-160 | Adapter for 205-S127 |
| 3 | 4630 | Inner pinion bearing |
| 4 | 205-383 | Depth Gauge/Aligner, Drive Pinion |
| 5 | 205-159 | Adapter for 205-S127 |
| 6 | 205-377 | Drive Pinion Gauge Tube |
| 7 | 205-226 | Depth Gauge/Aligner, Drive Pinion |
| 8 | 4010 | Rear axle housing outer (front) pinion bearing |
| 9 | 205-111 | Adapter for 205-S127 |
NOTE:
The Adapter must be offset to obtain an accurate reading.
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.
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.
NOTE:
If removed, press the speed sensor ring on with the differential ring gear.
