•Before removing the clock spring, refer to GROUP 52B, Service Precautions (P.52B-5) and Air Bag
Module and Clock Spring (P.52B-210). Also, put the front wheels in straight-ahead position.
Failure to do so may damage the SRS clock spring and render the SRS air bag inoperative, which
results serious driver injury.
•
*: Indicates parts which should be initially tightened, and then fully tightened after placing the
vehicle horizontally and loading the full weight of the engine on the vehicle body.
