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.
  1. Position the Drive Pinion Bearing Cup Installer and the inner and outer drive pinion bearing cups in their respective bores.
    1. After placing the inner and outer drive pinion bearing cups in their bores, place the Drive Pinion Bearing Cup Installer (inner) on the inner drive pinion bearing cup.
    2. Place the Drive Pinion Bearing Cup Installer (outer) on the outer drive pinion bearing cup.
    3. Install the Drive Pinion Bearing Cup Installer.

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

  3. Make sure the drive pinion bearing cups are correctly seated in their bores.
    4. 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)
  4. Assemble and position the Adapters.
    5. NOTE: This step duplicates final drive pinion bearing preload.
  5. Tighten the Adapter.
    • Tighten to 2.2 Nm (20 lb-in) rotational torque.

  6. Rotate the Adapter several half-turns to make sure of correct seating of the drive pinion bearings and position the Adapter.
  7. Install the Adapter.
    1. Position the Adapter.
    2. Install the 2 differential bearing caps.
    3. Install the 4 differential bearing cap bolts.
      • Tighten to 112 Nm (83 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 Adapter 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 final assembly of integral axle assemblies.
  8. 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 special tools.
