Check
-
Remove the differential.
Refer to: Differential Carrier (205-03 Front Drive Axle/Differential, Removal and Installation).
-
Remove and discard the ring gear bolts.
-
NOTICE:
Care should be taken not to damage the differential ring gear bolt hole threads.
Using the general equipments, remove the ring gear.
Use the General Equipment: Punch
Use the General Equipment: Copper Hammer
-
Install the Differential carrier, differential carrier bearing cups and differential bearing preload shims.
-
Install the differential bearing caps and bolts. Align the differential bearing caps in there original location.
Torque:
94 lb.ft (128 Nm)
-
Rotate the differential carrier to make sure the bearings have seated correctly.
-
Using the dial indicator, rotate the differential carrier and measure the differential carrier runout.
-
If the runout does not exceed the specification, install a new ring gear and pinion.
Use the General Equipment: Dial Indicator
-
If runout exceeds the specification, the ring gear
is true and the condition is due to differential carrier/differential
bearing damage.
-
Inspect the differential bearings and the
differential carrier. Always install new differential bearings when
installing a new differential carrier, or if a bearing condition is
questionable.
-
Remove the bolts and the differential bearing caps.
-
Remove the differential carrier, differential bearing cups, and differential bearing preload shims.
-
NOTE:
If necessary.
Using the special tool and the general equipment, remove and discard the differential bearings.
Use Special Service Tool: 205-D061
