Rear Differential Carrier Assembly

DIFFERENTIAL: REAR DIFFERENTIAL CARRIER ASSEMBLY:

INSPECTION

1. INSPECT DIFFERENTIAL CASE
(a) Check that the differential case is not damaged.
If the differential case assembly is damaged, replace the differential case.
2. INSPECT RUNOUT OF REAR DRIVE PINION COMPANION FLANGE SUB-ASSEMBLY






(a) Using a dial indicator, measure the runout of the companion flange vertically and horizontally.
Maximum runout:
Vertical runout: 0.10 mm (0.0039 in.)
Lateral runout: 0.10 mm (0.0039 in.)
3. INSPECT RUNOUT OF DIFFERENTIAL RING GEAR






(a) Using a dial indicator, check the runout of the ring gear.
Maximum runout:
0.07 mm (0.0028 in.)
If the runout is greater than the maximum, replace the ring gear with a new one.
4. INSPECT DIFFERENTIAL RING GEAR BACKLASH






(a) Using a dial indicator, check the backlash of the ring gear.
Backlash:
0.13 to 0.18 mm (0.0051 to 0.0071 in.)
If the backlash is not within the specification, adjust or repair the side bearing preload as necessary.
5. INSPECT DIFFERENTIAL DRIVE PINION PRELOAD






(a) Using a torque wrench, measure the preload of the backlash between the drive pinion and ring gear.
Preload (at starting):
0.56 to 0.85 N*m (5.7 to 8.7 kgf*cm, 5.0 to 7.5 in.*lbf)
6. INSPECT TOTAL PRELOAD






(a) Using a torque wrench, measure the total preload with the teeth of the drive pinion and ring gear in contact.
(b) Using a torque wrench, measure the total preload.
Total preload (at starting):
Drive pinion preload plus 0.39 to 0.59 N*m (4.0 to 6.0 kgf*cm, 3.5 to 5.2 in.*lbf)
If necessary, disassemble and inspect the differential.
