CAUTION: Once the steering column is removed
from the vehicle, the column is extremely
susceptible to damage. Dropping the column
assembly on its end could collapse the steering shaft
or loosen the slide block which maintains column
rigidity. Leaning on the column assembly could
cause the jacket to bend or deform. Any of the above
damage could impair the column's collapsible
design. If it is necessary to remove the steering
wheel, use only the specified steering wheel puller.
Under no conditions should the end of the shaft be
hammered upon, as hammering could loosen the
slide block which maintains column rigidity.Removal
1. Turn the steering wheel so that the vehicle's wheels
are pointing straight ahead.
2. Turn the ignition switch to ªLOCKº.
3. Disconnect the battery ground cable, and wait at least
5 minutes.
4. Disconnect the yellow 2-way SRS connector located
under the steering column.
