General Description
Front Drive Shaft ConstructionS6RW0D3111001
A constant velocity ball joint is used on the wheel side of both right and left side drive shaft assemblies. For A/T
vehicle, a tripod type constant velocity joint is used on the differential side and center shaft side. For M/T vehicle, a
double offset type constant velocity joint (DOJ) is used on the differential side and center shaft side. The drive shaft
can slide through the tripod joint or the double offset joint (DOJ) in the extension/contraction direction.

For tripod joint 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 (1) and tripod
joint housing (2) are washed thoroughly and air dried.
Replace boot(s) (3) 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) 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.7) Fasten boot bands (1) securely 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.

Disassembly
1) Using hydraulic press (1), draw out center shaft (2)
from center bearing.
2) Remove oil seals from center bearing support (3).
3) Remove bearing support circlip (1) using snap ring
pliers (2).
4) Remove center bearing from center bearing support.
Reassembly
Install center shaft by reversing removal procedure and
noting the following points.
• When installing bearing support circlip (1), make sure
that if fits in circlip groove in center bearing support (2)
securely as shown.

3) Install caliper and tighten caliper pin bolts to
specified torque.
Tightening torque
Caliper pin bolt (a): 26 N·m (2.6 kgf-m, 19.0 lb-ft)
4) Install front wheel referring to “Wheel (with Tire)
Removal and Installation in Section 2D”.
5) Check brake effectiveness.
Front Disc Brake Pad InspectionS6RW0D4206004
Check pad lining for wear. When the wear exceeds limit,
replace with new one.
CAUTION!
Never polish pad lining with sandpaper. If
lining is polished with sandpaper, hard
particles of sandpaper will be deposited in
lining and may damage disc. When pad lining
requires correction, replace it with a new one.

Front disc brake pad thickness (lining thickness)
Standard: 10 mm (0.39 in.)
Limit: 10 mm (0.39 in.)
NOTE
When pads are removed, visually inspect
caliper for brake fluid leak. Correct leaky
point, if any.

Installation
S6RW0D4206005
Removal
1) Hoist vehicle and remove front wheel.
2) Remove brake flexible hose joint bolt (1) from caliper
(2). As this will allow fluid to flow out of hose (3),
have a container ready beforehand.
3) Remove caliper pin bolts (1).
4) Remove caliper from caliper carrier.
Installation
1) Install caliper to caliper carrier.
2) Torque caliper pin bolts to specification.
NOTE
Make sure that boots are fit into groove
securely.
