NOTE:

Once the steering column is removed from the vehicle, the
column is extremely susceptible to damage. Dropping the
column assembly on the end could collapse the steering shaft
or loosen the plastic injections, which maintain column
rigidity. Leaning on the column assembly could cause the
jacket to bend or deform. Any of the above damage could
impair the columns collapsible design. Do NOT hammer on the
end of the shaft, because hammering could loosen the plastic
injections, which maintain column rigidity. If you need to
remove the steering wheel, refer to Steering Wheel
Replacement procedure in this section.

NOTE:

The front wheels of the vehicle must be maintained in the
straight ahead position and the steering column must be in the
LOCK position before disconnecting the steering column or
intermediate shaft. Failure to follow these procedures will
cause improper alignment of some components during
installation and result in damage to the SIR coil assembly.
