through several revolutions prior to removing the rear axle pinion flange (4851).
Remove the rear axle pinion flange. For additional information, refer to
Drive Pinion Flange in
this section.
11. Using a screwdriver, force the rear axle drive pinion seal metal flange up and strike it with a hammer.
12. Using gripping pliers and a hammer, remove the rear axle drive pinion seal (4676).
13. Remove the rear axle drive pinion shaft oil slinger (4670).
14. Using the special tool and a soft- faced hammer, drive the drive pinion gear out of the front
pinion bearing (4621) and remove it through the rear of the differential housing.
15. Remove and discard the differential drive pinion collapsible spacer (4662). Klj . 7 ba

16. Using the special tool and a suitable press, remove the pinion bearing (4630).
1. Position the special tool under the pinion bearing.
2. Using a press, remove the pinion bearing.
17. NOTE: Using a micrometer, measure the drive pinion bearing adjustment shim thickness. Use
this measurement as a reference to compare to the shim gauge reading taken prior to installing
the pinion bearing.
Remove the drive pinion bearing adjustment shim (4663).
18. Using a brass drift and a hammer, remove any damaged differential drive pinion bearing cup (4616) (4628) from the differential housing. Tap alternately on each side of the cup to prevent it
from cocking in the bore. Klj . 8 ba

19. If the differential ring gear backface runout measurement, taken at the beginning of this
procedure, did not exceed the specification, proceed to Final disassembly in this procedure. If
the differential ring gear backface runout measurement, taken at the beginning of this
procedure, exceeded the specification, the cause may be a warped differential ring gear, a
damaged differential case, or loss of differential bearing preload. Proceed to Excessive
differential ring gear backface runout in this procedure to verify the cause of the excessive
runout.

23.
NOTE: Apply pressure toward the left side to fully seat the differential bearing cup.
Install progressively larger differential bearing shims on the RH side until the largest differential
bearing shim selected can be assembled with a slight drag feel.
24. Install the RH differential bearing cap. zTighten both bearing caps to specification.
25. Rotate the differential assembly to make sure it turns freely. Klj . 10 ba
