the clock spring to the column switch.
Mating mark alignment
Turn the clock spring fully clockwise, and turn bac k it
approx. 3 and
turns counterclockwise to align the
mating marks.
Caution
If the clock spring’s mating mark is not properly
aligned, the steering wheel may not be completely
rotational during a turn, or the flat cable within the
clock spring may be severed, obstructing normal op-
eration of the SRS and possibly leading to serious
injury to the vehicle’s driver and passenger.
9. Install the steering column covers, steering whe el and
the air bag module.
10. Check steering wheel for noise, binds of diffic ult operation.
11. Check steering wheel for excessive free play.

(2) Before installing the bearing cap bolts, check that the,
shank length of each bolt “meets the limit., If, th e limit’
is exceeded, replace the bolt.
Limit (A): Max. 71.1 mm (2.80 in.)
(3) Apply engine oil to the threaded portion
sur-
face of the bolt.
(4) Tighten the bolts to 25 Nm

tightening sequence.
(5) Make a paint mark on the head of each bolt.
(6) Make a paint mark on the bearing cap at the pos ition
to from the paint mark made on the bolt in
the direction of tightening the bolt.
(7) According to the specified tightening sequence, give a

paint mark onthe bolt and that on the cap are in alignment.
Caution
If the bolt is turned less than proper fastening

tightening the bolt, therefore, be careful to
a sufficient turn to it.
2. If the bolt is overtightened (exceeding
loosen the bolt completely and then retighten it by
repeating the tightening procedure from step (1).
