Rear Differential Carrier Assembly Disassembly

Using a dial indicator, measure the runout of the companion flange vertically and laterally.

Maximum runout:

Runout	Specified Condition
Vertical runout	0.10 mm (0.0039 in.)
Lateral runout	0.10 mm (0.0039 in.)

1. If the runout is greater than the maximum, replace the companion flange.
   

Using a dial indicator, check the runout of the ring gear.

Standard maximum runout:

0.07 mm (0.0028 in.)

1. If the runout is greater than the maximum, replace the ring gear with a new one.
   

Using a dial indicator, check the backlash of the ring gear.

Standard backlash:

0.13 to 0.18 mm (0.0051 to 0.0071 in.)

1. If the backlash is not within the specification, adjust the side bearing preload or repair as necessary.
   

   HINT:

   Perform the measurements at 3 or more positions around the side bearing preload.

Using a torque wrench, measure the preload of backlash between the drive pinion and ring gear.

Standard preload (at start of torque):

0.56 to 0.85 N*m (6 to 9 kgf*cm, 4.9 to 7.5 in.*lbf)

1. If necessary, disassemble and inspect the differential.
   

Using a torque wrench, measure the preload with the teeth of the drive pinion and ring gear in contact.

Using a torque wrench, measure the total preload.

Standard total preload (at start of torque):

0.39 to 0.59 N*m (4 to 6 kgf*cm, 3.4 to 5.2 in.*lbf) + drive pinion preload

1. If necessary, disassemble and inspect the differential.
