Steering Wheel Free Play
PROCEDURES/SPECIFICATIONS:
Steering wheel
free play must be maintained within specified limits.
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:

shaft is loose.
9) POWER
STEERING
PROCEDURES/SPECIFICATIONS:

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).
REJECT VEHICLE IF:
More than 30 feet per mile on the approved
side slip indicator.
