Front Differential Carrier Assembly

DIFFERENTIAL: FRONT DIFFERENTIAL CARRIER ASSEMBLY:

INSPECTION

1. INSPECT BACKLASH DIFFERENTIAL RING GEAR AND DIFFERENTIAL DRIVE PINION






(a) Using SST and a dial indicator, measure the ring gear backlash.
SST: 09564-32011
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.
2. INSPECT FRONT 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.)
If the runout is greater than the maximum, replace the companion flange.
3. INSPECT DRIVE PINION PRELOAD






(a) Using a torque wrench, measure the preload of the backlash between the drive pinion and ring gear.
Torque: 0.49 to 0.78 Nm (5 to 8 kgf-cm, 4.3 to 6.9 in-lbf)
4. INSPECT TOTAL PRELOAD






(a) Using a torque wrench, measure the preload with the teeth of the drive pinion and ring gear in contact.
Total preload (at starting):
Drive pinion preload plus 0.25 to 0.45 N*m (2.5 to 4.6 kgf*cm, 2.2 to 4.0 in.*lbf)
If necessary, disassemble and inspect the differential.
