Power Steering Wheel Effort Inspection

PROCEDURE

1. On a vehicle standing on a flat, level surface, set the front wheels in the straight-ahead position.
2. Increase the engine speed to 1000 min⁻¹.

After the inspection, leave the engine running at idle speed.

3. Hook a spring scale to a spoke of the steering wheel at the point farthest from the center of the wheel. With the front wheels in the straight-ahead position, measure the force required to turn the steering wheel left and right.
Force: 34.3 N
4. Check that excessive force is not required to turn the steering wheel.
5. If the measured force exceeds the specified value, perform the following checks:
– inspect the lower arm ball joint and steering tie rod end dust boots for damage;
– torque required to rotate the ball stud of the steering tie rod end ball joint;
– torque required to rotate the ball stud of the lower arm ball joint.
