STEERING WHEEL
INSPECTION
1. CHECK STEERING WHEEL FREEPLAY
(a) With the vehicle stopped and tires pointed straight ahead,
rock the steering wheel gently back and forth with light fin-
ger pressure.
(b) Freeplay should not exceed the maximum. Maximum freeplay: 40 mm (1.58 in.)
If the freeplay exceeds the maximum, adjust it in the following
procedure.
2. ADJUST STEERING GEAR
(a) Point the front wheels straight ahead.
(b) Loosen the adjusting screw lock nut.
(c) Turn the cross shaft adjusting screw clockwise to de- crease steering wheel freeplay and counterclockwise to
increase it.
HINT:
Turn the adjusting screw in small increments and check the
freeplay between each adjustment.
(d) Turn the steering wheel half way around in both direc- tions.
(e) Check that the freeplay is correct and steering is smooth and without rough spots.
(f) Torque the adjusting screw lock nut (See page SR−41).
3. CHECK STEERING EFFORT
(a) Center the steering wheel.
(b) Remove the steering wheel pad (See page SR−11).
(c) Start the engine and run it at idle.
(d) Measure the steering effort in both directions.
