STEERING WHEEL AND COLUMN
On-vehicle inspection
Steering wheel play
With the wheels in the straight-ahead position, gently turn the
steering wheel to the left and right to determine if play is with-
in specification.
Play: O-30mm (O-l. 18 in)
Note
l if play exceeds specification, either the steering
joints are worn or the backlash of the steering gear
is excessive.
Looseness of steering wheel and column
Move the steering wheel in directions @ , @ , and @ to check
for column bearing wear, steering shaft joint play, steering
wheel looseness. and column looseness.
Steering wheel effort
1. With the vehicle on a hard level surface, move the steering
wheel to put the wheels in the straight-ahead position.
2. Attach a pull scale to the outer of the steering wheel, and
then starting with the wheels in the straight-ahead position,
check the steering effort required to turn the steering wheel
to the left and to the right.
3. If the measured effort exceeds specification, check the fol-
lowing: rotation-starting torque of the pinion, rotation torque
of each ball joint, and seizure of each joint.
Steering wheel effort: 108 N (11 kg, 24.2 lb) or less
Note
l Measure after turning the steering wheel to the left
and right 5 times or more.
