If the air intake duct is removed from the throttle body take great care to keep fingers away
from the throttle plate. The drive motor has very high torque and is capable of random move-
ment at any time. Do not under any circumstances activate the throttle plate by hand.
When removing the throttle body from the intake manifold disconnect the wiring first. During
replacement connect the wiring last.
Do not activate the throttle body using a DC suppy to test the motor,as permanent damage to
the throttle body will result.

GENERAL DESCRIPTION
FRONT AXLE26-2
GENERAL DESCRIPTIONM1261000100370
The front axle consists of front hubs, knuckles, wheel
bearings and drive shafts, and has the following fea-
tures:
The wheel bearing incorporates double-row
angular contact ball bearing for reduced friction.
The front wheel hub assembly combines the hub,
wheel bearing, and oil seal in a single unit for
fewer parts, better durability, improved assembly
precision, and better structural organization.
The driveshaft incorporates BJ-PTJ type constant
velocity joints with high transmission efficiency for
low vibration and noise.
Due to the use of the inner shaft and bracket
assembly, the right and left drive shafts are
approximately the same in length. This reduces
noise, vibration and torque steer.L-RH>
The dynamic damper is mounted on the LH drive-
shaft.
ABS rotor for detecting the wheel speed is
press-fitted to the BJ.
NOTE: .

PTJ: Pillow Tripod Joint
BJ: Birfield Joint

REMOVAL AND INSTALLATIONM1261003500429
For vehicles with ABS, do not strike the ABS rotors installed to the BJ outer race of drive shaft
against other parts when removing or installing the drive shaft. Otherwise the ABS rotors will be
damaged.
For vehicles with ABS, be careful not to strike the pole piece at the tip of the front wheel speed
sensor with tools during servicing work.

4. If the inner shaft is hard to remove from the transaxle, strike
the bracket assembly lightly with a plastic hammer and
remove the inner shaft.
Do not apply pressure to the wheel bearing by the vehicle
weight to avoid possible damage when the drive shaft is
removed. If, however, vehicle weight must be applied to
the bearing to move the vehicle, temporarily secure the
wheel bearing by using special tools MB991000 and
MB990998.

REAR AXLE DIAGNOSIS
REAR AXLE27-3
SYMPTOM PROCEDURESM1271004400222
INSPECTION PROCEDURE 1: Abnormal Noise
DIAGNOSIS
STEP 1. Check the rear hub assembly installation bolts for
looseness.
Q: Are the rear hub assembly installation bolts loosened?
YES : Tighten the rear hub assembly installation bolts to the
specified torque 73
7 Nm (54 5 ft-lb). Then go to
St e p 4 .
NO : Go to Step 2.
STEP 2. Check the wheel bearing end play.
(1) Remove the caliper assembly, and suspend the caliper
assembly with a wire and remove the brake disc.
(2) Check the bearing's end play. Place a dial gauge against
the hub surface; then move the hub in the axial direction
and check whether or not there is end play.
Limit: 0.05 mm (0.002 inch)
Q: Is the wheel bearing end play within the limit?
YES : Go to Step 3.
NO : Replace the rear hub assembly, then go to Step 4.
STEP 3. Check the rear hub rotary-sliding resistance.
(1) Remove the caliper assembly, and suspend the caliper
assembly with a wire and remove the brake disc.
(2) Turn the hub a few times to seat the bearing.
(3) Wind a rope around the hub bolt and turn the hub by pulling
at a 90
angle with a spring balance. Measure to determine
whether or not the rotary-sliding resistance of the rear hub
is within the limit value.
Limit: 24 N (5.4 lbs)
Q: Is the rear hub rotary-sliding resistance within the limit?
YES : Go to Step 4.
NO : Replace the rear hub assembly, then go to Step 4 .
STEP 4. Retest the systems.
Q: Are abnormal noises generated?
YES : Return to Step 1.
NO : The procedure is complete.
