2. Measure the play on the steering wheel 

circumference before the wheels start to move 
when slightly moving the steering wheel in both 
directions.

Limit: 30 mm

3. When the play exceeds the limit, check for the 

play on the steering shaft and steering linkage 
connection. Correct or replace.

4. If the free play still exceeds the limit value, set the 

steering wheel straight ahead with the engine 
stopped. Load 5 N towards the steering wheel 
circumference and check the play.

Standard value (steering wheel play with the 
engine stopped): 10 mm or less

5. If the play exceeds the standard value, remove 

the steering gear (Refer to 

P.37-19

) and check 

the total pinion torque (Refer to 

P.37-24

).

STEERING ANGLE CHECK

M1372001100471

1. Place the front wheel on a turning radius gauge 

and measure the steering angle.

Standard value:
<Vehicles with 16 inch wheel>

<Vehicles with 17 inch wheel>

2. If the steering angle is not within the standard 

value, adjust the toe-in as follows. 

Standard value:

at the centre of tyre tread: 0 

± 3 mm

Toe angle (per wheel): 0

°00' ± 08'

3. Loosen the lock nut, and unclip the bellows.
4. Adjust the toe-in by turning the left and right tie 

rod turnbuckles by the same amount (in opposite 
directions).
NOTE: The toe will move out as the left 
turnbuckle is turned toward the front of the vehicle 
and the right turnbuckle is turned toward the rear 
of the vehicle.

5. Tighten the lock nut to the specified torque, and 

tighten the bellows by the clip.

Tightening torque: 52 

± 2 N⋅m

6. Recheck the steering angle.
