DISASSEMBLY

1.

CHECK COMPANION FLANGE RUNOUT

Using a dial indicator, measure the vertical and lateral runout of
the companion flange.

Maximum: runout: 0.09 mm (0.0035 in.)

If the runout exceeds the maximum, replace the companion
flange.

2.

CHECK RING GEAR RUNOUT

Using a dial indicator, measure the ring gear runout.

Maximum runout: 0.05 mm (0.0020 in.)

If the runout exceeds the maximum, replace the ring gear.

3.

CHECK RING GEAR BACKLASH

Using a dial indicator, while holding the companion flange, mea-
sure the ring gear backlash.

Backlash: 0.13 – 0.18 mm (0.0051 – 0.0071 in.)

HINT:
Measure at 3 or more positions around the circumference of the
ring gear.
If the backlash is not within the specified value, adjust the side
bearing preload or repair as necessary.
4.

CHECK TOOTH CONTACT BETWEEN RING GEAR
AND DRIVE PINION (See page 

SA–119

)

5.

CHECK SIDE GEAR BACKLASH

Using a dial indicator, measure the side gear backlash while
holding one pinion gear toward the case.

Backlash: 0.05 – 0.20 mm (0.0020 – 0.0079 in.)

If the backlash is not within the specified value, replace the side
gear thrust washer of the different thickness (See page 

SA–119

).

6.

MEASURE DRIVE PINION PRELOAD

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

Preload (at starting):
0.8 – 1.1 N·m (8 – 11 kgf·cm, 7.0 – 9.7 in.·lbf)

7.

CHECK TOTAL PRELOAD

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

Total preload (at starting):
Drive pinion preload plus 0.4 – 0.6 N·m (4 – 6 kgf·cm,
3.5 – 5.2 in.·lbf)

If necessary, disassemble and inspect the differential.
8.

REMOVE COMPANION FLANGE

(a)

Using a chisel and hammer, unstake the staked part of the
nut.

(b)

2WD:
Remove the companion flange nut.
(1)

Using a torx

®

 soket (E8), remove the stud bolt and

loosen the 3 bolts so that the heads come out 40
mm (1.57 in.).

(2)

Set the SST and install the 3 nuts to the companion
flange.

SST

09213–58013

(3)

Install the other SST to the set SST to hold the com-
panion flange, and remove the nut.

SST

09330–00021

(4)

Remove the 3 nuts, stud bolts and SST from the
companion flange.

(a)

Using SST, remove the bearing from the drive pinion.
SST

09556–22010

If the front bearing is damaged or worn, replace the front bear-
ing.
(b)

Remove the 2 washers and bearing spacer.

11.

(c)

Using SST and a plastic hammer, remove the 2 side bear-
ing plate washers.
SST

09504–22012

HINT:
Measure the plate washer thickness and note it down.
(d)

Remove the differential case with the bearing outer races
from the carrier.

HINT:
Tag the bearing outer races to show the location for reassem-
bling.
12.

REMOVE DRIVE PINION FROM DIFFERENTIAL CAR-
RIER
