PROCEDURE
REMOVE FRONT DIFFERENTIAL CASE OIL SEAL
Using SST, remove the front differential case oil seal from the front differential case.
REMOVE FRONT DIFFERENTIAL CASE FRONT TAPERED ROLLER BEARING
| *a | Turn |
| *b | Hold |
Using SST, remove the front differential case front tapered roller bearing from the front differential case.
REMOVE FRONT DIFFERENTIAL CASE REAR TAPERED ROLLER BEARING
| *a | Turn |
| *b | Hold |
Using SST, remove the front differential case rear tapered roller bearing from the front No. 1 differential case sub-assembly.
REMOVE FRONT DIFFERENTIAL RING GEAR
Mount the front differential ring gear in a vise between aluminum plates.
Note
Be careful not to damage the front differential ring gear.
Do not overtighten the vise.
| *a | Matchmark |
Put matchmarks on the front differential ring gear and front No. 1 differential case sub-assembly.
Remove the 16 bolts.
Using a plastic-faced hammer, remove the front No. 1 differential case sub-assembly from the front differential ring gear.
INSPECT FRONT NO. 1 DIFFERENTIAL CASE SUB-ASSEMBLY
REMOVE FRONT DIFFERENTIAL PINION SHAFT STRAIGHT PIN
Using a 5 mm pin punch and hammer, remove the front differential pinion shaft straight pin from the front No. 1 differential case sub-assembly.
REMOVE FRONT NO. 1 DIFFERENTIAL PINION SHAFT
Remove the front No. 1 differential pinion shaft from the front No. 1 differential case sub-assembly.
INSPECT FRONT DIFFERENTIAL PINION BACKLASH
REMOVE FRONT DIFFERENTIAL SIDE GEAR
Set SST as shown in the illustration and tighten it.
| *a | Turn | *b | Hold |
Note
Do not overtighten SST, as doing so will damage the front differential side gear, conical spring, front No. 1 differential side gear thrust washer and front No. 1 differential case sub-assembly.
Tech Tips
Tighten SST until there is a clearance between the front differential pinions and front differential side gears.
When removing the front differential pinions, do not overtighten SST, as it is necessary to rotate the front differential side gears.
| *a | Turn |
Install SST as shown in the illustration, rotate the front differential side gear, and then remove the 2 front differential pinions and 2 front differential pinion thrust washers from the front No. 1 differential case sub-assembly.
Note
Do not drop the front differential pinion and front differential pinion thrust washer.
| *1 | Front Differential Side Gear |
| *2 | Conical Spring |
| *3 | Front No. 1 Differential Side Gear Thrust Washer |
Remove SST from the front No. 1 differential case sub-assembly, and then remove the 2 front differential side gears, 2 front No. 1 differential side gear thrust washers and 2 conical springs from the front No. 1 differential case sub-assembly.
Note
Do not drop the front differential side gear, front No. 1 differential side gear thrust washer and conical spring.
