Except 2JZ±GTE M/T
0.5±0.8 NVm (5±8 kgfVcm, 4.3±6.9 in.Vlbf)
wIf the preload is greater than the specification, replace
the spacer and repeat the preload procedure.
wIf the preload is less than the specification, retighten the
nut 13 NVm (130 kgfVcm, 9 ftVlbf) at a time until the
specified preload is reached.

nut, replace the spacer and repeat the preload procedure.
Do not back off the nut to reduce the preload.
23. CHECK DRIVE PINION SHAFT RUNOUT
Measure the drive pinion shaft runout at a point 10 mm (0.39
in.) from the end of the shaft.
Maximum runout:
0.08 mm (0.0031 in.)
24. INSTALL DIFFERENTIAL CASE IN CARRIER
(See page SA±73)
25. INSTALL O±RING

(b) Coat MP grease onto the snap ring.
(c) Using a hammer and brass bar, install both side gear shafts.
NOTICE: Be careful not to damage the side gear shaft
and the oil seal.
HINT: Whether or not the side gear shaft is making contact
with the pinion shaft can be known by the sound or feeling
when driving it in.
30. INSPECT DIFFERENTIAL CARRIER

mating surfaces of the 2 side gear shafts, as shown.
Standard Distance:
2JZ±GTE M/T

1. DIFFERENTIAL ASSEMBLY REMOVAL
(See page SA±60)
2. REMOVE DIFFERENTIAL MOUNT CUSHION
Using SST, remove the differential mount cushion.
SST 09316±12010, 09570±24010
NOTICE:
wWhen driving out the mount cushion, be careful not
to touch the member with the SST.
wAlign the SST straight so that the bolt of the SST is
parallel with the center line of the mount cushion.
wWhen installing the bolts to the LH and RH
differential mount cushions, make sure the bolts are
passed through the correct holes in the SST, as
shown in the illustration.
3. INSTALL DIFFERENTIAL MOUNT CUSHION
Using SST, install the cushion so that the marks are posi-
tioned, as shown in the illustration.
SST 09570±24010
NOTICE:
wDo not make a mistake with left and right sides or top
and bottom.
wSet the SST after temporarily installing the
differential mount cushion into the member so as
not to be installed at an angle.
wTo confirm that the differential mount cushion is
aligned straight in relation to the member, check
that the SST is fully in contact with all of the cushion.
