INSPECT TOTAL PRELOAD
Using a torque wrench, measure the total preload with the teeth of the drive pinion and ring gear in contact.
| Standard total preload |
|---|
| Drive pinion preload + 0.39 to 0.59 N*m (4 to 6 kgf*cm, 3 to 5 in.*lbf) |

Tag the 2 bearing outer races and 2 adjusting nuts to show the location for reassembling.
REMOVE DIFFERENTIAL DRIVE PINION
Remove the drive pinion and bearing spacer from the differential carrier.
REMOVE REAR DRIVE PINION REAR TAPERED ROLLER BEARING
Using SST and a press, press out the rear drive pinion rear tapered roller bearing from the drive pinion.
Note
Do not drop the drive pinion.
If the drive pinion or ring gear is damaged, replace them as a set.

REMOVE DIFFERENTIAL OIL STORAGE RING
Using a brass bar and hammer, tap out the oil storage ring from the differential carrier.
REMOVE REAR DRIVE PINION REAR TAPERED ROLLER BEARING
Using a brass bar and a hammer, tap out the rear drive pinion rear tapered roller bearing outer race from the differential carrier.
REMOVE DIFFERENTIAL RING GEAR
| *a | Matchmark |
Place matchmarks on the ring gear and differential case.
Using a screwdriver and a hammer, unstake 5 ring gear plates.
Remove the 10 bolts and 5 ring gear plates.
Using a plastic hammer, tap on the ring gear to separate it from the differential case.
INSPECT DIFFERENTIAL CASE ASSEMBLY RUNOUT
Install the 2 rear differential case bearing outer races to the differential case.
Install the differential case to the differential carrier.
Install the 2 bearing caps to the differential carrier with the 4 bolts.
Using a dial indicator, measure the differential case runout.
| Maximum runout |
|---|
| 0.07 mm (0.00276 in.) |
