9) Remove drive shaft assembly.
10) Remove center bearing support bolts (3) and remove
center bearing support (2) with center shaft (1) from
differential side gear, if equipped.
Installation
CAUTION!
• Be careful not to damage oil seals and
boots when installing drive shaft.
• Do not hit joint boot with hammer.
Inserting joint only by hands is allowed.
• Make sure that differential side joint is
inserted fully and its snap ring is seated as
it was.

Install drive shaft assembly by reversing removal
procedure and noting the following points.
• Tighten each bolt and nut to the specified torque
referring to “Front Drive Shaft Assembly Components
Location”.
• Tighten brake hose mounting bolt to specified torque.
Tightening torque
Brake hose mounting bolt: 25 N·m (2.5 kgf-m,
18.0 lb-ft)
• Fill transaxle with oil as specified referring to “Manual
Transaxle Oil Change in Section 5B” or “A/T Fluid
Change in Section 5A” and “Transfer Oil Change in
Section 3C” (4WD model).
• Check toe setting referring to “Front Wheel Alignment
Inspection and Adjustment in Section 2B” and adjust
as required.
Front Drive Shaft Disassembly and ReassemblyS6RW0D3116004

For DOJ type
CAUTION!
Disassembly of wheel side joint is not
allowed. If any noise or damage exists in it,
replace it as assembly.

1) Remove differential side (or center shaft side) boot
big band (1) as follows.
• For boot big band without joint [A]:
Remove boot big band by tapping boot and band
with plastic hammer. If it is hard to remove boot
big band, cut it using a nipper or an iron saw with
care not to damage joint housing.
• For boot big band with joint [B]:

For tripod joint type
CAUTION!
• Disassembly of wheel side joint is not
allowed. If any noise or damage exists in it,
replace it as assembly.
• Do not disassemble tripod joint spider. If
any malcondition is found in it, replace it
as differential side joint assembly.

1) Remove differential side (or center shaft side) boot
big band (1) as follows.
• For boot big band without joint:
Remove boot big band by tapping boot and band
with plastic hammer. If it is hard to remove boot
big band, cut it using a nipper or an iron saw with

band.2) Wipe off grease from shaft and take off snap ring (1)
using snap ring pliers (2).
3) Remove tripod joint spider (1) using 3 arms puller
(2).
CAUTION!
To prevent any problem caused by washing
solution, do not wash tripod joint except its
housing. Degreasing of tripod joint with cloth
is allowed.

4) Remove differential side (or center shaft side) boot
small band, and then pull out differential side (or
center shaft side) boot from shaft.
5) Remove damper from shaft, if equipped.
6) Undo caulking (5) of wheel side boot big band (1)
and small band (3) using flat end rod (2) or the like,
then pull out wheel side boot (4) from shaft.

Reassembly
For DOJ type
Judging from abnormality noted before disassembly and
what is found through visual check of component parts
after disassembly, prepare replacing parts and proceed
to reassembly.
Make sure that wheel side joint assembly and DOJ
housing are washed thoroughly and air dried.
Replace boot(s) with new one(s).
CAUTION!
• Do not wash boots in degreaser such as
gasoline or kerosene. etc. Washing in
degreaser causes deterioration of boot.
• To ensure full performance of joint as
designed, be sure to distinguish between
two types of grease in repair set and apply
specified volume to respective joint
referring to the followings for identification
of the grease.

1) Wash disassembled parts (except boots). After
washing, dry parts completely by blowing air.
2) Clean boots with cloth.
3) Apply grease to wheel side joint. Use specified
grease in tube in wheel side boot set as a spare
parts.
Grease color
: Black
Amount
: 55 – 75 g (1.9 – 2.6 oz)
4) Install wheel side boot on shaft.
5) Fill up boot inside with specified grease.
6) Fit boot (1) to grooves of shaft and housing (2).
7) Insert screw driver into boot and allow air to enter
boot so that air pressure in boot becomes the same
as atmospheric pressure.
8) Place new wheel side boot big band (3) and small
band (4) onto boot putting band outer end (1) against
forward rotation (2) as shown in figure.9) Fasten boot bands (1) using special tool as shown in
figure.
CAUTION!
Do not squeeze or distort boot when
fastening it with bands.
Distorted boot caused by squeezing air may
reduce its durability.
