then measure the intermediate position of the distance.
- Align rear cover cap projection (A) with the marking position of
gear housing assembly (B).
- Install slit part of lower joint (C) aligning with the rear cover cap
projection (A). Make sure that the slit part of lower joint (C) is
aligned with rear cover cap projection (A) and the marking position
of gear housing assembly (B).
 Adjust neutral position of steering angle sensor. Refer to BRC-66,
"ADJUSTMENT OF STEERING ANGLE SENSOR NEUTRAL
POSITION : Special Repair Requirement".
 Check the following after installation:
- Check if steering wheel turns smoothly when it is turned several times fully to the end of the left and right.
- Check the steering wheel play, neutral position steering wheel, steering wheel turning force, and front wheel
turning angle. Refer to ST-9, "
Inspection".
