Differential Bearings: Installation
WARNING: This page is about a different car, the 2013 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
- Position the Drive Pinion Bearing Cup Installer and the inner and outer bearing cups in their respective bores.
- After placing the inner and outer bearing cups in their respective bores, place the Drive Pinion Bearing Cup Installer on the inner bearing cup.
- Place the Drive Pinion Bearing Cup Installer on the outer bearing cup.
- Install the Drive Pinion Bearing Cup Installer.
- Tighten the Drive Pinion Bearing Cup Installer to seat the pinion bearing cups in their bores.
- Make sure the differential pinion bearing cups are correctly seated.
- Assemble and position the Adapters.
- Tighten the Adapter.
- Tighten to 2.2 Nm (20 lb-in) rotational torque.
- Rotate the Adapter several half turns to make sure of correct seating of the drive pinion bearings and position the Adapter.
- Install the Adapter.
- Position the gauge tube.
- Install the 2 differential bearing caps.
- Install the 4 differential bearing cap bolts.
- Tighten to 112 Nm (83 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 all of the Adapters.
- Using the Shaft Bearing Cone Installer and Bearing Oil Seal Plate and a shop press, drive the inner drive pinion bearing and drive pinion bearing adjustment shim until they are firmly seated on the pinion shaft.
- Install a new drive pinion collapsible spacer on the pinion shaft against the pinion shaft shoulder.
- Install the drive pinion assembly into the axle housing.
- Install the outer drive pinion bearing and the drive pinion shaft oil slinger.
- Install the drive pinion seal and flange. For additional information, refer to DRIVE PINION FLANGE AND DRIVE PINION SEAL .
- Using the Differential Side Bearing Installer, install the 2 new differential bearings.
- 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:
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 | 205-105 | Adapter for 205-S127 (1.612 in OD) (T76P-4020-A3) |
| 2 | 205-111 | Adapter for 205-S127 (T76P-4020-A11) |
| 3 | 4621 | Drive pinion bearing (outer) |
| 4 | 205-109 | Adapter for 205-S127 (T76P-4020-A9) |
| 5 | 4630 | Drive pinion bearing (inner) |
| 6 | 205-129 | Adapter for 105-S127 (1.1884 in thick) (T79P-4020-A18) |
| 7 | 205-110 | Adapter for 205-S127 (1.7 in thick) (T76P-4020-A10) |
NOTE:
This step duplicates final drive pinion bearing preload.
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 Adapter and gauge tube. This will minimize selection of a drive pinion bearing adjustment shim thicker than required, which results in a deep tooth contact in final assembly of integral axle assemblies.
