STEERING WHEEL AND COLUMN 6E – 15
DAEWOO V–121 BL4
STEERING COLUMN
(Left–Hand Drive Shown, Right–Hand Dirve
Similar)
Important : Remove the steering column only if the follow-
ing conditions exist:
S The steering column requires replacement.
S The steering and the ignition lock housing require
replacement.
S Another operation requires the removal of the
steering column.
Notice : The steering column is extremely susceptible to
damage after it has been removed from the vehicle. Drop-
ping the column assembly on its end or hammering the
end of the steering shaft can collapse the steering shaft or
loosen the plastic injections which maintain column rigid-
ity. Leaning on the column can cause it to bend or deform.
Any of the above damage can impair the column’s collaps-
ible design. If it is necessary to remove the steering wheel,
use only the specified steering wheel puller.
Removal Procedure
1. Disconnect the negative battery cable and let the
vehicle sit for 1 minute to deactivate the airbag.
2. Remove the the lower instrument trim panels. Refer
to Section 9E, Instrumentation/Driver Information.
3. Remove the upper and the lower steering column
cover panel by removing the screws.
