When testing for steering wheel free play on vehicles equipped with power steering, the engine must be running.

Complete the following procedures to determine amount of steering wheel free play:

Move the steering wheel one direction until movement of tires is detected.

Make a chalk mark on the steering wheel at the 12 o'clock position.

Move the steering wheel in the opposite direction until movement of the tires is again detected and then make a second chalk mark at the 12 o'clock position.

Measure the distance between the two marks to determine the steering wheel free play, using the table below to determine if the vehicle is within specified limit.

The steering wheel free play will be maintained in accordance with the following table:

PROCEDURES/SPECIFICATIONS:

The pitman arm on the steering gear output shaft must be securely attached.

Inspect the pitman arm on the steering gear output shaft for any looseness.

REJECT VEHICLE IF:

Pitman arm on the steering gear output shaft is loose.

9) POWER STEERING

PROCEDURES/SPECIFICATIONS:

Inspect power steering lines and steering gear box for severe leakage (not slight dampness) and proper fill level (i.e., manufacturer's designated indicator line).

Inspect the power steering cylinder for secure attachment.

Inspect the auxiliary power assist cylinder for any looseness.

REJECT VEHICLE IF:

Power steering fluid leaks severely (not slight dampness) or fluid level does not meet indicator line.

Power steering cylinder is not securely attached.

Auxiliary power assist cylinder is loose.

10) TIE ROD ENDS, DRAG LINK ENDS, STEERING DAMPER AND IDLER ARMS

PROCEDURES/SPECIFICATIONS:

All clamps, bolts and threaded joints of tie rod and drag links must be securely tightened.

While the vehicle is on the ground (not jacked up) inspect the tie rod ends, drag link ends, steering damper and idler arms while a second person moves the steering wheel from side to side.

12) TOE-IN/TOE-OUT

PROCEDURES/SPECIFICATIONS:

AGENCY NOTE: Vehicles with an independent suspension on the front axle should not be driven over the wheel alignment indicator immediately after the front end has been raised. A false reading may occur if the vehicle front end is lowered and then within a few feet driven across the alignment indicator. The front wheels will not have had sufficient distance to resume their normal tracking. The vehicle should either be raised after crossing the wheel alignment indicator or should be backed up 10 feet or more before being driven forward across the indicator.

With wheels held in a straight ahead position, drive vehicle slowly over the approved drive-on side slip indicator (i.e., wheel alignment indicator).

Excessive toe-in or toe-out is a general indication that a complete check should be made of all front wheel alignment factors (caster, camber, steering axis inclination).
