DISASSEMBLY AND REASSEMBLY
Caution
(1) On the vehicles with ABS or ACD, when the drive shaft is disassembled or reassembled, be
careful not to interfere with the rotor for wheel speed sensor installed to the B.J. outer race
to prevent the rotor from damage.
(2) Never disassemble the B.J. assembly except when replacing the B.J. boot.

DISASSEMBLY SERVICE POINTS
AA"T.J. CASE/SPIDER ASSEMBLY REMOVAL
1. Wipe off grease from the spider assembly and the inside
of the T.J. case.
2. Always clean the spider assembly when the grease
contains water or foreign material.
Caution
Do not disassemble the spider assembly.
AB"T.J. BOOT REMOVAL
1. Wipe off grease from the shaft spline.
2. When reusing the T.J. boot, wrap plastic tape around
the shaft spline to avoid damaging the boot.
REASSEMBLY SERVICE POINTS
"AASPIDER ASSEMBLY/T.J. CASE INSTALLATION
1. Apply the specified grease furnished in the repair kit to
the spider assembly between the spider axle and the
roller.
Specified grease: Repair kit grease
Caution
(1) The drive shaft joint uses special grease. Do not
mix old and new or different types of grease.
(2) If the spider assembly has been cleaned, take
special care to apply the specified grease.
2. Install the spider assembly to the shaft from the direction
of the spline bevelled section.
3. After applying the specified grease to the T.J. case, insert
the drive shaft and apply grease one more time.
Specified grease: Repair kit grease
Amount to use: 120±10 g
NOTE
The grease in the repair kit should be divided in half
for use, respectively, at the joint and inside the boot.
Caution
The drive shaft joint uses special grease. Do not mix
old and new or different types of grease.Bevelled

"BAT.J. BOOT BAND (SMALL)/T.J. BOOT BAND
(LARGE) INSTALLATION
Set the T.J. boot bands at the specified distance in order
to adjust the amount of air inside the T.J. boot, and then
tighten the T.J. boot bands securely.
Standard value (A): 85±3mm
INSPECTION
DCheck the drive shaft for damage, bending or corrosion.
DCheck the drive shaft spline part for wear or damage.
DCheck the spider assembly for roller rotation, wear or
corrosion.
DCheck the groove inside T.J. case for wear or corrosion.
DCheck the boots for deterioration, damage or cracking.
DCheck the dust cover for damage or deterioration.
B.J. BOOT (RESIN BOOT) REPLACEMENT
1. Remove the B.J. boot bands (large and small).
NOTE
The B.J. boot bands cannot be re-used.
2. Remove the B.J. boot.
3. Wrap a plastic tape around the shaft spline, and assemble
the B.J. boot band and B.J. boot.
4. Install the groove in the center of the small diameter
part of the resin boot by fitting to the groove of the shaft.
5. Turn the adjusting bolt on the special tool so that the
size of the opening (W) is at the standard value.
Standard value (W): 2.9 mm

Tighten the adjusting bolt.

Loosen the adjusting bolt.
NOTE
(1) The value of W will change by approximately 0.7
mm for each turn of the adjusting bolt.

(2) The adjusting bolt should not be turned more than
once.
6. Install the boot band (small) in order to create clearance as
A and B in the illustration.
7. Use the special tool to crimp the B.J. boot band (small).
Caution
(1) Secure the drive shaft in an upright position and
clamp the part of the B.J. boot band to be crimped
securely in the jaws of the special tool.
(2) Crimp the B.J. boot band until the special tool
touches the stopper.
8. Check that the crimping amount (C) of the B.J. boot band
is at the standard value.
Standard value (C): 2.4 - 2.8 mm

Readjust the value of (W) in step 5 according
to the following formula, and then repeat the
operation in step 7.
W = 5.5 mm - C
Example: If C = 2.9 mm, then W = 2.6 mm.

Remove the B.J. boot band, readjust the value
of (W) in step 5 according to the following
formula, and then repeat the operations in
steps 6 and 7 using a new B.J. boot band.
W = 5.5 mm - C
Example: If C = 2.3 mm, then W = 3.2 mm.
9. Check that the B.J. boot band is not sticking out past
the place where it has been installed.
If the B.J. boot band is sticking out, remove it and then
repeat the operations in steps 6 to 8 using a new B.J.
boot band.

10. Fill the inside of the B.J. boot with the specified amount
of the specified grease.
Specified grease: Repair kit grease
Amount to use: 110±10 g
Caution
The drive shaft joint uses special grease. Do not mix
old and new or different types of grease.
11. Install the groove in the center of the large diameter part of
the resin boot by fitting to the groove of the shaft.
12. Follow the same procedure as in step 5 to adjust the
size of the opening (W) on the special tool so that it
is at the standard value.
Standard value (W): 3.2 mm
13. Install the boot band(large) in order to create clearance
as D and E in the illustration.
14. Use the special tool to crimp the B.J. boot band (large)
in the same way as in step 7.
15. Check that the crimping amount (F) of the B.J. boot band
is at the standard value.
Standard value (F): 2.4 - 2.8 mm

Readjust the value of (W) in step 12 according
to the following formula, and then repeat the
operation in step 14.
W = 5.8 mm - F
Example: If F = 2.9 mm, then W = 2.9 mm.

Remove the B.J. boot band, readjust the value
of (W) in step 12 according to the following
formula, and then repeat the operations in
steps 13 and 14 using a new B.J. boot band.
W = 5.8 mm - F
Example: If F = 2.3 mm, then W = 3.5 mm.
16. Check that the B.J. boot band is not sticking out past
the place where it has been installed.
If the B.J. boot band is sticking out, remove it and then
repeat the operations in steps 13 to 15 using a new
B.J. boot band.

REAR AXLE -General Information27B-2
GENERAL INFORMATION
The rear axle consists of rear hubs, wheel bearings,
drive shafts, and rear differential and, it has the
following features.
DThe wheel bearing is a unit bearing (double-row
angular contact ball bearing).
DThe drive shaft incorporates B.J.-T.J. type
constant velocity joints with high transmission
efficiency and low vibration and noise.DABS rotors for detecting the wheel speeds are
press-fitted to the B.J. outer wheels in vehicles
with ABS or ACD.
