Components Tests

Steering Linkage

1. 1. Grasp the steering wheel firmly and move it up and down and to the left and right

without turning the steering wheel to check the steering column bearing for wear,
steering column shaft for wear, steering wheel for looseness and steering column
for looseness. If the steering column bearing or the steering column shaft is worn
install a new steering column.
REFER to: Steering Column (211-04 Steering Column, Removal and Installation).
If the steering wheel or the steering column is loose, tighten the steering wheel or
the steering column retaining bolts.

2. 2. With the road wheels in the straight ahead position, gently turn the steering wheel

to the left and the right to check for free play in the steering linkage.

3. 3. There should be no excessive free play at the steering wheel rim. If there is

excessive free play, CHECK the tie-rod inner and outer ball joints, REFER to Tie-Rod
Component Test in this procedure. CHECK the steering column universal joint,
REFER to Steering Column Universal Joint Component Test in this procedure. If
there is no free play in the tie-rod and the steering column, install a new steering
gear.
REFER to: Steering Gear (211-02 Power Steering, Removal and Installation).

Tie-Rod

1. 1. Noises such as knocks, which may appear to originate from the steering linkage,

may also be generated by front suspension components.
REFER to: Noise, Vibration and Harshness (NVH) (100-04 Noise, Vibration and
Harshness, Diagnosis and Testing).

2. 2. Raise and support the vehicle.

REFER to: Lifting (100-02 Jacking and Lifting, Description and Operation).

3. 3. Firmly grasp the road wheel and apply a rocking motion checking for any free play

in the wheel bearing or suspension components.

4. 4. Turn the steering wheel to position the steering linkage against the right-hand

steering lock stop.

5. 5. With the aid of another technician holding the steering linkage against the right-

hand steering lock stop, firmly grasp the road wheel and apply a rocking motion
checking for any free play in the steering linkage.

6. 6. Detach the steering gear boot from the steering gear body and check for free play

at the tie-rod inner ball joint.

7. 7. If there is free play at the tie-rod inner ball joint, install a new tie-rod.

REFER to: Tie Rod (211-03 Steering Linkage, Removal and Installation).

8. 8. Check the tie-rod end for free play. Install a new tie-rod end if necessary.

REFER to: Tie Rod End (211-03 Steering Linkage, Removal and Installation).

9. 9. Turn the steering wheel to position the steering linkage against the left-hand

steering lock stop.

10. 10. With the aid of another technician holding the steering against the left-hand
