Subaru Legacy Service Manual: Disassembly

To detect the real cause of trouble, inspect the following items before disassembling.

Tooth contact and backlash between hypoid driven gear and drive pinion

Hypoid driven gear runout on its back surface

Total preload of drive pinion

1. Set the ST on vise and install the differential assembly to ST.

Rear cover

4. Remove the bolts, and then remove the rear cover.

5. Remove the stud bolts from rear cover if necessary.

6. Remove the side retainer attachment bolts, set the ST to differential case, and extract the side retainers RH and LH with a puller.

NOTE:

Side retainer shim of each side should be kept together with its mating retainer.

Keep the side retainers separate by attaching tags or in similar ways to make it possible to identify RH and LH sides during reassembly.

7. Pull out the differential case assembly from the differential carrier.

NOTE:

Be careful not to hit the teeth of hypoid driven gear against the differential carrier.

8. Remove the oil seal and O-ring from the side retainer.

9. When replacing the side bearing, remove the bearing race from the side retainer using ST.

10. Using the ST, remove the bearing cone.

NOTE:

Do not attempt to disassemble the parts unless necessary.

Set the ST so that its claws catch the edge of the bearing cone.

Never mix up the RH and LH bearing races and cones.
