FUNCTION CHECK
(1) Raise the vehicle so that all four wheels may turn freely.
(2) Start the engine, running the vehicle at an indicated speed
of about 80 km/h (50 mph).
(3) Turn the steering wheel all the way to left and right and
turn it swiftly, checking to ensure that the rear wheels
steer to the same directions as the front wheels.
REAR OIL PUMP DISCHARGE FLOW VOLUME
CHECK
(1) Disconnect the pressure hose from the rear oil pump
and install the special tool with a rubber hose.
(2) Place the other end of the rubber hose in a container
which permits measurement of flow rate (2-dm3 graduated
cylinder).
(3) Start the engine. Increase speed slowly, then hold the
indicated speed of 50 km/h (31 mph), measuring discharge
flow volume for 30 seconds.
Caution
While performing this work, continuously add fluid
into the oil reservoir.
Standard value: Approximately 1.0 dm3 (1.06 qts.)
(4) If the discharge flow volume is extremely high or low,
the rear oil pump should be replaced.
BALL JOINT ROTATION STARTING TORQUE
CHECK
(1) Holding the power cylinder tie rod with a spanner, discon-
nect the tie rod and trailing arm.
(2) After swinging the ball joint stud several times, install
the stud nut, then measure the ball joint rotation starting
torque with the special tool.
Standard value: 0.5 Nm (4 in.lbs.) or less
(3) If the rotation starting torque exceeds the standard value,
replace the tie rod end.
(4) If the rotation starting torque is less than the standard
value, check that the ball joint is not loose and operates
smoothly. If not, it may be reused.
