Differential Bearings: Installation
WARNING: This page is about a different car, the 2014 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 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.
-
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.
-
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.
Install the new drive pinion bearings and Adapters as shown.
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 7 205-937 Depth Gauge/Aligner, Drive Pinion 8 4010 Rear axle housing outer (front) pinion bearing 9 205-111 Adapter for 205-S127 -
NOTE: This step duplicates final drive pinion bearing preload.
Tighten the Adapter.
- Tighten to 2.2 Nm (20 lb-in).
-
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.
- 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).
-
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.
- 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.
- Install the differential carrier. Refer to DIFFERENTIAL CARRIER .
- Install the drive pinion seal and flange. Refer to DRIVE PINION FLANGE AND DRIVE PINION SEAL .
