BACKLASH
1. Install a bolt to the companion flange.
2. Fit a dial gauge onto the bolt.
3. Measure the circumference backlash of the companion flange,
and check that it satisfies the standard below.
lIf outside the standard, disassemble it to check and adjust
each part.
TOOTH CONTACT
1. Remove the pinion sleeve assembly, and apply red lead to the
drive gear.
CAUTION:
Apply red lead to the both faces of 3 to 4 gears at 4 loca-
tions evenly spaced on the drive gear.
2. Install the pinion sleeve shims and pinion sleeve assembly.
3. Remove the plug on the upper side of the transfer case.
4. Rotate the companion flange back and forth several times, and
check the drive pinion gear to drive gear tooth contact by view-
ing from the plug hole.Backlash : 0.13 - 0.19 mm (0.0051 - 0.0075 in)

sion X) in the following manner:

lIf the tooth contact is near the face (face contact), or near the
heal (heal contact), thin the pinion sleeve shims to move the
drive pinion gear closer to the drive gear.
lIf the tooth contact is near the flank (flank contact), or near the
toe (toe contact), thicken the pinion sleeve shims to move the
drive pinion gear farther from the drive gear.
PRELOAD TORQUE
Pinion bearing preload torque
1. Remove the pinion sleeve assembly, and rotate the companion flange back and forth in 2 to 3 times.
Check for abnormal noise, rotation malfunction, and other malfunctions.
2. Rotate the companion flange at least 20 times to check for smooth operation of the bearing.

3. Using a preload gauge, measure the preload torque of the pin-
ion bearing.
CAUTION:
Every rotational part shall rotate smoothly with the speci-
fied gear oil.
lIf outside the standard, disassemble the pinion sleeve assem-
bly to check and adjust each part.
Overall preload torque
1. Measure pinion bearing preload torque (P1).
2. Install the pinion sleeve shims and pinion sleeve assembly.
3. Rotate the companion flange at least 20 times to check for smooth operation of the bearing.
4. Using a preload gauge, measure the overall preload torque.
lIf outside of the standard, disassemble it to check and adjust
each part. If measuring the overall preload torque after the disassembly, measure it with the transfer
case oil seals and gear ring oil seals removed, then install the oil seals.
COMPANION FLANGE RUNOUT
1. Fit a dial gauge onto the companion flange face (inner side of
the propeller shaft mounting bolt holes).
2. Rotate the companion flange to check for runout.
3. Fit a test indicator to the inner side of the companion flange
(socket diameter).
4. Rotate the companion flange to check for runout.
5. If the runout value is outside the repair limit, follow the procedure
below to adjust.
a. While changing the phase between companion flange and drive pinion gear by 90°at a time, check runout
and determine which phase angle minimizes the runout.
b. If the runout value is still outside of the limit after the phase has been changed, replace the companion
flange.
c. If the runout is outside the standard after the companion flange is replaced, adjust the assembly status of
the pinion bearings and drive pinion gear, or replace the pinion bearings.Preload torque
