Removal and Installation
1. Loosen the lock nut C, and loosen the A nut. Remove the cable
from the clutch cylinder.
CAUTION:
+Do not remove the B nut because this requires the inner
cable extension adjustment.
+Before installing the A and C nuts, use seal tape to wrap
the clutch cylinder thread area and cable thread area.
2. Remove the clamp and other fasteners which secure the cable.
3. Remove the stabilizer actuator connector.
4. Remove the stabilizer actuator.
5. Remove the clutch cylinder.
6. Before removing the stabilizer control unit, remove cluster lid C
and audio equipment. Refer to the BT section ``INSTRUMENT
PANEL''.
