CAUTION:
Do not hammer the end of the shaft. Hammering it will
loosen the plastic shear pins which maintain the column
length and impair the collapsible design of the column.
INSTALLATION
1) Install steering wheel to steering shaft with 2 lugs on combina-
tion switch fitted in two grooves in the back of steering wheel and
also aligning marks on steering wheel and steering shaft.
2) Tighten steering shaft nut to specified torque.

4) Tighten steering column cover screws.
CAUTION:
When installing lower cover and upper cover, be careful
so that combination switch lead wire is not caught be-
tween covers.
5) Install steering column hole cover.
6) Install steering wheel to steering column. Refer to ªSTEERING
WHEELº in this section.
7) Connect battery negative cable.
STEERING COLUMN ASSEMBLY
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 plastic shear pins which
maintain column length. Leaning on the column assembly
could cause it to bend or deform.
Any of the above damage could impair the column's col-
lapsible design.
When loosening steering column mounting bolts, make
sure that steering column assembly and steering shaft low-
er assembly have been separated. Loosening them with
steering column assembly and steering shaft lower assem-
bly assembled could cause damage to bearing in steering
shaft lower assembly.
NOTE:
When servicing steering column or any column-mounted
component, remove steering wheel. But when removing steer-
ing column simply to gain access to instrument panel compo-
nents, leave steering wheel installed on steering column.
REMOVAL
1) Disconnect negative battery cable at battery terminal.
