REMOVAL OF DRIVE SHAFT NUTLoosen the drive shaft nut while the vehicle is on the floor
with the brakes applied.
DISCONNECTION OF FRONT SPEED SENSOR
Remove the mounting bolts which hold the speed sensor
bracket to the knuckle, and then remove the speed
sensor.
Caution
Be careful when handling the pole piece at the tip of the
speed sensor and the toothed edge of the rotor so as
not to damage them by striking against other parts.
REMOVAL OF CALIPER ASSEMBLY
Remove the caliper assembly and suspend it with wires.
9. DISCONNECTION OF LOWER ARM BALL JOINT Using the special tool, disconnect the lower arm ball joint
from the knuckle.
Caution
1. Be sure to tie the cord of the special tool to the
nearby part.
2. Loosen the nut but do not remove it.
11. DISCONNECTION OF TIE ROD END
Using the special tool, disconnect the tie rod end from the
knuckle.
Caution

2. REMOVAL OF CALIPER ASSEMBLY
Remove the caliper assembly and suspend it with a piece
of wire.
8. REMOVAL OF REAR ROTOR
Caution
Care must be taken not to scratch or otherwise damage
the teeth of the rotor. The rotor must never be dropped.
If the teeth of the rotor are chipped, resulting in a
deformation of the rotor, it will not be able to accurate- ly detect the wheel rotation speed, and the system will
not function normally.
INSPECTIONM27MFAAI
l Check the oil seal for crack or damage.
l
Check the surface of bearings for seizure, discoloration or
roughened raceway.
l Check the rear hub for wear or damage.
