RELEASE METHOD OF AIRBAG ACTIVATION PREVENTION MECHANISM
An airbag activation prevention mechanism is built into the connector for the squib circuit of the SRS.
When release of the airbag activation prevention mechanism is directed in the troubleshooting procedure,
as shown in the illustration on the following pages, insert paper which has the same thickness as the male
terminal, between the terminal and short spring.
CAUTION:
Never release the airbag activation prevention mechanism on the steering wheel pad connector.
NOTICE:

Do not release the airbag activation prevention mechanism unless specifically directed by the
troubleshooting procedure.

If the inserted paper is too thick the terminal and short spring may be damaged, so always use
paper with the same thickness as the male terminal.

REMOVAL
NOTICE:
The hub bearing could be damaged if it is subjected
to the vehicle weight, such as when moving the ve-
hicle with the drive shaft removed.
Therefore, if it is absolutely necessary to place the ve-
hicle weight on the hub bearing, first support it with
the SST.
SST 09608–16042 (09608–02021, 09608–02041)
w/ ABS:
After disconnecting the drive shaft from the axle hub,
work carefully so as not to damage the ABS speed
sensor rotor serration on the drive shaft.
1. REMOVE FRONT WHEEL
2. DRAIN OUT GEAR OIL
3. w/ ABS:
REMOVE BOLT AND ABS SPEED SENSOR
4. REMOVE DRIVE SHAFT LOCK NUT
(a) Remove the cotter pin and lock cap.
(b) While applying the brakes, remove the nut.
5. DISCONNECT TIE ROD END FROM STEERING
KNUCKLE (See Pub. No. RM599E on page SA–11)
6. DISCONNECT LOWER BALL JOINT FROM LOWER
SUSPENSION ARM (See Pub. No. RM599E on page
SA–11)
7. DISCONNECT DRIVE SHAFT FROM AXLE HUB
(a) Using a plastic hammer, disconnect the drive shaft from
the axle hub.
NOTICE:
Cover the drive shaft boot and ABS speed sensor rotor with
cloth to protect it from being damaged.
(b) Push the front axle hub toward the outside of the vehicle
to separate the drive shaft from the axle hub.
8. REMOVE DRIVE SHAFTS

(b) Coat the gear oil to the inboard joint shaft and differential case sliding surface.
(c) Set the snap ring with opening side facing downward.
(d) Using a brass bar and hammer, install the drive shaft.
NOTICE:
Be careful not to damage the dust cover of the drive shaft and oil seal lip of the transaxle.
HINT:
Whether the inboard joint shaft is in contact with the pinion shaft or not can be known from the sound or feel-
ing when driving it in.
(e) Check that there is 2 – 3 mm (0.08 – 0.12 in.) of play in the axial direction.
(f) Check that the drive shaft cannot be removed by hand.
2. RH drive shaft:
INSTALL DRIVE SHAFT TO TRANSAXLE
(a) Coat the gear oil to the inboard joint shaft and differential case sliding surface.
(b) Install the drive shaft with the center bearing bracket.

3. CONNECT DRIVE SHAFT TO AXLE HUB
NOTICE:
Be careful not to damage the boot and ABS speed sensor rotor.
4. CONNECT LOWER SUSPENSION ARM TO LOWER BALL JOINT
Torque: 127 N·m (1,300 kgf·cm, 94 ft·lbf)
5. CONNECT TIE ROD END TO STEERING KNUCKLE
(a) Connect the tie rod end to the steering knuckle.
(b) Install the nut and a new cotter pin.
If the holes for the cotter pin are not aligned, tighten the nut further up to 60.
Torque: 49 N·m (500 kgf·cm, 36 ft·lbf)
6. INSTALL DRIVE SHAFT LOCK NUT
(a) While applying brakes, install the nut.
Torque: 216 N·m (2,200 kgf·cm, 159 ft·lbf)
(b) Install the lock cap and a new cotter pin.
If the holes for the cotter pin are not aligned, tighten the nut further up to 60.
7. w/ABS:
INSTALL ABS SPEED SENSOR AND BOLT
Torque: 8.0 N·m (82 kgf·cm, 71 in.·lbf)
8. FILL AND CHECK GEAR OIL (See page MX–4)

INSPECTION
1. CHECK FLUID LEVEL
(a) Keep the vehicle level.
(b) With the engine stopped, check the fluid level in the oil
reservoir.
If necessary, add fluid.
Fluid: ATF DEXRON II or III
HINT:
Check that the fluid level is within the HOT LEVEL range on the
reservoir / reservoir cap dipstick.
If the fluid is cold, check that it is within the COLD LEVEL range.
(c) Start the engine and run it at idle.
(d) Turn the steering wheel from lock to lock several times to
boost fluid temperature.
Fluid temperature: 80
C (176
F)
(e) Check for foaming or emulsification.
If there is foaming or emulsification, bleed power steering sys-
tem (See Pub. No. RM599E on page SR–5).
(f) With the engine idling, measure the fluid level in the oil
reservoir.
(g) Stop the engine.
(h) Wait a few minutes and remeasure the fluid level in the oil
reservoir.
Maximum fluid level rise: 5 mm (0.20 in.)
If a problem is found, bleed power steering system (See Pub.
No. RM599E on page SR–5).
(i) Check the fluid level.

pump [See Pub. No. RM599E on page SR–21 (4A–FE
and 7A–FE engines), SR–24 (3S–FE engine) and see
page SR–8 (2C–T, 2C–TE and 1CD–FTV engines)].
(b) Connect SST, as shown in the illustration below.
SST 09640–10010 (09641–01010, 09641–01030,
