1. With the engine stationary and the steering wheel in the straight-ahead position, apply a force of 5 N (0.5 kg, 1.1 lbs.) to the steering wheel in the peripheral direction.
Standard value: 26.6 mm (1.05 in.) or less Limit: 50 mm (1.97 in.)
2. If the measured value exceeds the repair limit, check the steering gear backlash and ball joint axial play.
Limit: 0.5 mm (0.020 in.)
3. If the measured value exceeds the limit, screw in the steering gear box adjusting bolt until steering wheel free play is within the range of standard value.
3. If the measured displacement exceeds the centre graduation (B), replace the ball joint.

1. Place the front wheel on a turning radius gauge and measure the steering angle.
Standard value:
Inner wheel 32°40′ 0-3. Outer wheel 29°45′
2. If the steering angle is outside the standard value, after checking the toe-in, (Refer to GROUP 33–Service Adjust-ment Procedures), adjust the steering angle with the stopper bolt.

Remove the breather plug and check the oil level in the steering gear box by using a special gauge or a thin screwdriver.
Standard value: 25 mm (0.98 in.)
E37FFAG
Caution After checking the engine r/min., there must be a return to the standard idling r/min.
3. Measure the tangential force with a spring balance by turning the steering wheel clockwise and counterclockwise one and a half turns.
4. If the stationary steering effort exceeds the standard value, check for belt slackness, damage, insufficient oil, air mixed into oil, collapsed or twisted hoses, etc., and repair if found.
To check for the return of steering wheel to centre, carry out drive test and check the following points.
When the steering wheel is turned abruptly, momentary hard steering might result, but this does not mean any problem. It is caused by low oil pump delivery during idling.
