Thermometer
A Pocket THERMOMETER is available at either a industrial hardware
store or a refrigerant supplier.
Electronic leak detector
An ELECTRONIC LEAK DETECTOR can be available at either a spe-
cialty tool supplier or an A/C equipment supplier.

7) Note the low-pressure gauge reading.
8) Leave it at least 5 minutes, and then check the
low-pressure gauge reading for any changes.
If the gauge indicator shows near zero point, it is a
sign of leakage. Check pipe connector points, re-
pair them, and make sure there is no leakage.
9) Follow the can tap operation manual, install to
the refrigerant can.
10) Disconnect the center manifold hose from the
vacuum pump, and connect the hose to the tap
valve.
11) When a 13.6 kg (30 lb) refrigerant container is
used, measure the weight of the refrigerant amount
to use using a scale.
12) Confirm that all the 3 hoses are connected se-
curely to the manifold gauge set.
13) Open the valve on the HFC-134a source.
14) Loosen the center hose connection on the
manifold gauge set (if applicable, press a purge
valve on the manifold gauge set) for a few seconds
to allow the air in the center hose to escape by the
refrigerant pressure.
15) Stop the engine and carefully open the high-
pressure valve.
CAUTION:
Do not open the low-pressure valve.
CAUTION:
Never run the engine while charging from the
high-pressure side.
16) Close the high-pressure valve when the low-
pressure gauge reaches 98 kPa (1 kg/cm2, 14 psi).
Using a leak tester, check the system for leaks.
If any leakage is found after the refrigerant recov-
ery is completed, repair the applicable area.

(4) Obtain the thickness of pinion height adjust-
ing washer to be inserted from the following for-
mula, and replace the temporarily installed
washer with this one.
NOTE:
Adjust it using the 0 — 3 washers.
T = To + N – 0.05 mm (0.0020 in)
(Example of calculation)
To = 0.15 mm (0.0020 in)
N = 0.1 mm (0.0039 in)
T = 0.15 mm (0.0020 in) + 0.1 mm (0.0039 in) –
0.05 mm (0.0020 in) = 0.2 mm (0.0079 in)
Result: Thickness = 0.2 mm (0.0079 in)
Therefore use part number 32295AA370.
3) Install the selected pinion height adjusting wash-
er on drive pinion, and press the rear bearing cone
into position with ST.

4) Insert the drive pinion into the differential carrier,
and install the preselected bearing preload adjust-
ing collar and washer.
5) Set ST and differential carrier to the press and
install the front bearing cone.

General Diagnostic Table
POWER ASSISTED SYSTEM (POWER STEERING)
10.General Diagnostic Table
A: INSPECTION
*1 If the tires or wheels are wider than standard, the load to the power steering system is increased. Accordingly, in a condition,
for example before fluid warms-up, relief valve may work before reaching maximum turning angle. In this case, steering effort
may be heavy. When the measured hydraulic pressure is normal, there is no abnormal thing. *2 In cold weather, flow resistance will increase due to the cold hydraulic fluid, and steering effort will be heavier. After warming-up en-
gine, turn the steering wheel from stop to stop several times to warm-up fluid. If steering effort reduces normally, function is normal. *3 I n c o l d w e a t h e r o r w i t h i n s u f f i c i e n t w a r m – u p o f t h e e n g i n e , s t e e r i n g e f f o r t m a y b e h e a v y d u e t o e x c e s s i v e d r o p o f i d l e r p m w h en
