SERVICE POINTS OF REMOVALM2618AH
1. DISCONNECTION OF FRONT SPEED SENSORRemove 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 asnot to damage them by striking against other parts.
3. REMOVAL OF DRIVE SHAFT NUT
Loosen the drive shaft nut while the vehicle is on the floor
with the brakes applied.
Caution
Do not apply vehicle load to the wheel bearing loosingthe drive shaft nut. If, however, vehicle load must be
applied to the bearing in moving the vehicle, temporari-
ly secure the wheel bearing by using the special tools,
MB990998-01, etc.
4. REMOVAL OF CALIPER ASSEMBLY
Remove the caliper assembly and suspend it with wires.
8. DISCONNECTION OF LOWER ARM BALL JOINT
Using the special tool, disconnect the lower arm ball joint
from the knuckle.
Caution1. Be sure to tie the cord of the special tool to the
nearby part.2. Loosen the nut but do not remove it.
IO. DISCONNECTION OF TIE ROD ENDUsing the special tool, disconnect the tie rod end 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. REMOVAL OF DRIVE SHAFTUse the special tool to push out the drive shaft from the
front hub.
14. REMOVAL OF HUBIn the case of AWD-vehicles with A.B.S., take care not to
damage the rotor for A.B.S. installed to the B.J. outer race
when removing the hub.

Caution
Be careful when handling the pole piece at the tip of thespeed sensor and the toothed edge of the rotor so as
not to damage them by striking against other parts.
2. REMOVAL OF CALIPER ASSEMBLY
Remove the caliper assembly and suspend it with a piece of
wire.
8. REMOVAL OF REAR ROTOR
CautionCare must be taken not to scratch or scar the rotor’s
toothed surface, and not to drop it.
If the rotor’s toothed surface is chipped or the rotor is
deformed, it might not be able to accurately sense the
wheel rotation speed and the system as a result mightnot perform normally.

(I) Using the MUT, force-drive the actuator and fix the damping force changeover.
(2) Check service data (Item No. 61 through 64) to verify that the actuator has been force-driven.
NOTE
lAll of the four actuators in the shock absorbers are simultaneously changed over by forced drive.
lThe damping force changed over and fixed by forced drive is cleared by the following three conditions.1. Ignition switch OFF
2. Vehicle speed 3 km/h (1.9 mph) or more
3. MUT disconnected
