PROCEDURE

1. REMOVE STEERING LOCK ACTUATOR ASSEMBLY

(a) Secure the steering column assembly in a vise between aluminum plates.

NOTICE:

Do not overtighten the vise.

(b) Using SST, strike a punch mark for drilling in the center of the steering lock set bolt.

NOTICE:

When striking the punch mark, in order to prevent impact force from being applied to the steering lock actuator assembly, do not use a normal center punch.

(d) Using the screw extractor, remove the 2 steering lock set bolts, upper steering column clamp and steering lock actuator assembly.

Inspection

INSPECTION

PROCEDURE

1. INSPECT STEERING COLUMN ASSEMBLY
