STEERING NOISE
There is some noise in all power steering systems. One of the most common is a hissing sound evident at a
standstill parking. Or when the steering wheel is at the end of it’s travel. Hiss is a high frequency noise similar
to that of a water tap being closed slowly. The noise is present in all valves that have a high velocity fluid passing
through an orifice. There is no relationship between this noise and steering performance.

POWER STEERING RETURN LINE
DESCRIPTION
Power steering return line is a hose which is
clamped at the pump and the gear.
OPERATION
Power steering return line, is used to transfer low
pressure power steering fluid, from the power steering gear to the power steering pump.
DIAGNOSIS AND TESTING
POWER FLOW AND PRESSURE
The following procedure is used to test the operation of the power steering system on the vehicle. This
test will provide the gallons per minute (GPM) or
flow rate of the power steering pump along with the
maximum relief pressure. Perform test any time a
power steering system problem is present. This test
will determine if the power steering pump or power
steering gear is not functioning properly. The following pressure and flow test is performed using Power
Steering Analyzer Tool Kit 6815 (Fig. 2) and Adapter
Kit 6893.
(4) Disconnect high pressure hose at the pump.
Use a container for dripping fluid.
(5) Connect Tube 6865 to the pump hose fitting.
(6) Connect the power steering hose from the
steering gear to Adapter 6826.
(7) Open the test valve completely.
(8) Start engine and let idle long enough to circulate power steering fluid through flow/pressure test
gauge and to get air out of the fluid. Then shut off
engine.
(9) Check fluid level, add fluid as necessary. Start
engine again and let idle.
(10) Gauge should read below 862 kPa (125 psi), if
above, inspect the hoses for restrictions and repair as
necessary. The initial pressure reading should be in
the range of 345-552 kPa (50-80 psi).
(11) Increase the engine speed to 1500 RPM and
read the flow meter. The reading should be 2.4 - 2.8
GPM, if the reading is below this specification the
pump should be replaced.
CAUTION: The next step involves testing maximum
pump pressure output and flow control valve operation. Do not leave valve closed for more than three
seconds as the pump could be damaged.
(12) Close valve fully three times and record highest pressure indicated each time. All three read-
ings must be above specifications and within
345 kPa (50 psi) of each other.
• Pressures above specifications but not within
345 kPa (50 psi) of each other, replace pump.
• Pressures within 345 kPa (50 psi) of each other
but below specifications, replace pump.
(13) Open the test valve, turn steering wheel
extreme left and right positions against the stops.
Record the highest indicated pressure at each position. Compare readings to specifications. If highest
output pressures are not the same against either
stop, the gear is leaking internally and must be
repaired.

FLOW AND PRESSURE TEST
(1) Check the power steering belt to ensure it is in
good condition and adjusted properly.
(2) Connect pressure gauge hose from the Power
Steering Analyzer to Tube 6865.
(3) Connect Adapter 6826 to Power Steering Ana-
lyzer test valve end.
CAUTION: Do not force the pump to operate
against the stops for more than 2 to 3 seconds at a
time because, pump damage will result.

NOTE: Before performing this procedure, the worm
bearing preload adjustment must be performed.
(1) Rotate the stub shaft with a 12 point socket
from stop to stop and count the number of turns.
(2) Starting at either stop, turn the stub shaft
back 1/2 the total number of turns. This is the center
of the gear travel (Fig. 27).
(3) Place the torque wrench in the vertical position
on the stub shaft. Rotate the wrench 45 degrees each
side of the center and record the highest rotational
torque in this range (Fig. 28). This is the Over-Center Rotating Torque.
NOTE: The stub shaft must rotate smoothly without
sticking or binding.
(4) Rotate the stud shaft between 90° and 180° to
the left of center and record the left off-center preload. Repeat this to the right of center and record the
right off-center preload. The average of these two
recorded readings is the Preload Rotating Torque.
(5) The Over-Center Rotating Torque should be
0.40-0.70 N·m (3-7 in. lbs.) higher than the Preload
Rotating Torque.
(6) If an adjustment to the Over-Center Rotating
Torque is necessary, first loosen the adjuster lock
nut. Then turn the pitman shaft adjuster screw back
