b) STEERING SYSTEM
1) GENERAL REQUIREMENTS
PROCEDURES/SPECIFICATIONS:
All steering system components must be capable of
				free movement.
Instruct a second person to move the steering
				mechanism from one extreme position to the other while observing the
				movement.
Inspect all steering system components for any
				modification or other condition that interferes with free movement.

				interfered with the free movement of any steering component.
2) 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:

				be applied to eliminate wheel bearing looseness). Either grasp wheel at top and
				bottom or use a bar for leverage. Attempt to rock wheel in and out. Check for

				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.

				condition.
Inspect all threaded joints for loose
				condition.
Inspect ball and socket joints for movement.
REJECT VEHICLE IF:

Any movement under steering load of a ball and
				socket joint (i.e., tie rod ends and drag link ends). Any motion, other than
				rotational, between any linkage member and its attachment point of more than
				1/4 inch.
11) NUTS
PROCEDURES/SPECIFICATIONS:
All component nuts must be properly located on the
				tie rods, pitman arm, drag link, steering arm or tie rod arm and must be
				securely tightened.
Inspect nuts on tie rods, pitman arm, drag link,
				steering arm and tie rod arm for their presence and secure attachment.
REJECT VEHICLE IF:
Nuts are loose or missing on tie rods, pitman arm,
				drag link, steering arm or tie rod arm.
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.

Rubber bushing is partially or completely
				missing.

B) Leaf
PROCEDURES/SPECIFICATIONS:
With the vehicle on the ground (not jacked up),
				instruct a second person to rock the steering wheel and observe the side to
				side movement of the leaf spring, shackles and bushings from under the
				vehicle's hood.
The front of the vehicle must be jacked up on
				chassis for checking front suspension. With the use of a pry bar and using
				frame as a pivot, attempt to pry front and rear spring attachments and check
				for movement.
Inspect the following:
Bushings or pivot;
Center bolts;
Hangers;
Shackles;
Springs; and
U-bolts.
