2. Disconnect the fluid pipes between the steering unit and the

fluid reservoir, and the fluid hose between the pump and the

fluid reservoir.

3. When draining is completed, remove remaining fluid within

hydraulic system by turning the steering wheel to stop in

both directions several times.

Refilling

1. Connect the fluid lines securely and fill the fluid reservoir

with specified automatic transmission fluid.

2. When the fluid reservoir is filled to the specified level, allow

2 or 3 minutes.  While refilling, keep fluid reservoir

replenished as necessary to prevent air from entering the

hydraulic system.

3. Lower the front wheels to the ground.  Start and let the

engine idle for a few minutes.

Recheck the fluid level and replenish if necessary.

STEERING WHEEL PLAY
Inspection

1. Check the amount of the steering wheel play by turning the

wheel in both directions until the tires begin to move with the

front wheels properly in the straight-ahead position.

Note:
If the vehicle is equipped with a power steering unit, the
wheel free play should be checked with the engine
running.

2. Also check the steering wheel for play and looseness in

mount by moving it back and forth and sideways.  While

driving check for hard-steering, steering shimmy and

tendency of steering to pull to one side.

Adjustment

1. Align the front wheels properly in the straight ahead

position.

2. Loosen the lock nut on the adjusting screw of the steering

unit.

3. Turn the adjust screw clockwise to decrease free play or

counter-clockwise to increase.

4. After check of specified free play, tighten the lock nut to

specified torque.

AIR BLEEDING

Fill fluid reservoir with specified automatic transmission fluid
(DEXRON) and turn the steering wheel to lock in both
directions repeatedly, so that level of fluid in the reservoir to the
specified level and start the engine.
Perform the following check with the engine running at idle.
Bleeding is considered to be completed if the following
conditions apply;
(1) Turn the steering wheel to lock in both directions 3 or 4

times.

A buzz is not produced in the hydraulic line.

(2) Stop the engine with steering wheel in a straight ahead

position.

Level of fluid in reservoir does no increase.

Note:
Do not hold the steering wheel in position of lock for more
than 5 seconds, or temperature of fluid increases sharply.
