When installing the steering column, finger-tighten all of the lower bracket and joint bolts; then tighten

them to specification. Do not apply undue stress to the steering column.

NOTE:

• With the wheels in the straight ahead position, align the slit of the

lower joint with the projection on the dust cover. Insert the joint until

surface (A) contacts surface (B).

• After installation, inspect the steering column for proper operation.

INSPECTION AFTER INSTALLATION

• Check the tilt device for proper tilt range.

• Check that the steering wheel turns smoothly to the left and right

locks.

• Check that the number of turns are the same from the straight-for-

ward position to the left and right locks.

• Check that the steering wheel is in the neutral position when driv-

ing straight ahead.
