REAR DIFFERENTIAL CARRIER ASSEMBLY DISASSEMBLY
PROCEDURE
FIX REAR DIFFERENTIAL CARRIER ASSEMBLY IN PLACE
INSPECT RUNOUT OF REAR DRIVE PINION COMPANION FLANGE SUB-ASSEMBLY REAR
*a
Vertical Runout
*b
Lateral Runout
Using a dial indicator, measure the runout of the companion flange vertically and laterally.
Distance from center to runout measurement point
30 mm (1.18 in.)
Maximum Runout
Item
Specified Condition
Vertical runout
0.14 mm (0.00551 in.)
Lateral runout
0.14 mm (0.00551 in.)
If the runout is more than the maximum, replace the companion flange.
INSPECT RUNOUT OF DIFFERENTIAL RING GEAR
Using a dial indicator, measure the runout of the ring gear.
Maximum runout
0.07 mm (0.00276 in.)
If the runout is more than the maximum, replace the ring gear with a new one.
INSPECT DIFFERENTIAL RING GEAR BACKLASH
Using a dial indicator, measure the backlash of the ring gear.
Standard backlash
0.10 to 0.18 mm (0.00394 to 0.00708 in.)
If the backlash is not within the specification, adjust the side bearing preload or perform repairs as necessary.
Tip:Perform the measurement at 3 or more positions around the circumference of the ring gear.
INSPECT DIFFERENTIAL DRIVE PINION PRELOAD
Using a torque wrench, measure the preload of the backlash between the drive pinion and ring gear.
Standard preload (at starting)
0.88 to 1.98 N*m (9 to 20 kgf*cm, 8 to 17 in.*lbf)
If necessary, disassemble and inspect the differential.
INSPECT TOTAL PRELOAD
Using a torque wrench, measure the preload with the teeth of the drive pinion and ring gear in contact.
Standard total preload (at starting)
Drive pinion preload plus 1.08 to 2.38 N*m (12 to 24 kgf*cm, 10 to 21 in.*lbf)
If necessary, disassemble and inspect the differential.
REMOVE REAR DRIVE PINION NUT
Using SST and a hammer, loosen the staked part of the rear drive pinion nut.
