(d) With SST and the transfer RH bearing sub-
assembly in close contact, install the transfer RH
bearing retainer sub-assembly together with SST
into the transfer case.
NOTICE:
Avoid interference between the case and the
retainer, and between the SST and the transfer
ring gear mounting case.
HINT:
If the engagement is tight, tap SST with a hammer
placing a brass bar on the center of SST.
(e) Make sure that the transfer RH bearing retainer sub-
assembly and transfer case contact closely.
(f) Tighten the 7 bolts evenly in order shown in the
illustration.

(g) Remove the SST.
15. INSPECT DIFFERENTIAL RING GEAR BACKLASH
(a) Set the dial gauge perpendicular to the ring gear
face, fix the driven pinion, and check backlash by
moving the ring gear.
Backlash:
0.10 to 0.15 mm (0.0039 to 0.0059 in.)
NOTICE:

17. ADJUST TOTAL PRELOAD
(a) Using SST(s) and a torque wrench, measure the
initial torque with the driven pinion bearing contact
with the ring gear face.
SST 09326-20011
Torque: New bearing
+0.2 to 0.4 N*m (+2.3 to 3.9 kgf*cm, 1.8
to 3.5 in.*lbf)
Used bearing
+0.15 to 0.30 N*m (+1.6 to 3.1 kgf*cm,
1.3 to 2.7 in.*lbf)
NOTICE:
Before measurement, rotate the bearing in both

bearing retainer sub-assembly together with SST
into the transfer case.
NOTICE:
• Avoid interference between the case and the
retainer, and between the SST and the
transfer ring gear mounting case.
• Carefully check the retainer's O-ring for
damage and incorrect fitting.
HINT:
• If the engagement is tight, tap SST with a
hammer placing a brass bar on the center of
SST.
• If SST and retainer are not in close contact, the
seal for the inner end of the retainer may not be
properly aligned when the retainer goes into
position. This may result in the lip of the oil seal
being rolled back during installation.
• If SST and retainer are not in close contact, the
center of the retainer or transfer ring gear
mounting case may come out of position when
the retainer is being installed. This can cause the
lip of the oil seal to be rolled back.
