CAUTION: The wheel of the vehicle must be straight
ahead and the steering column in the "LOCK"
position before disconnecting the steering column
from the steering gear. Failure to do so will cause
the SRS coil assembly to become uncentered which
will cause damage to the SRS coil assembly. (with
SRS air bag)
