Inspection of fluid pressure
1. Assemble the SST as shown in the figure.
Tightening torque:
39-49 Nern (4.0-5.0 m-kg, 29-36 ft-lb)
2. Disconnect the pressure hose on the oil pump side, and
attach the SST.
Note
l Before disconnecting the hose, make marks at the
connections for proper reinstallation.
3. Bleed the air from the system. (Refer to page N-26.)
4. Open the gauge valve fully. Start the engine and turn the
steering wheel fully left and right to raise the fluid tempera-
ture to 50-60°C (122-14OOP).
5. Close the gauge valve completely. Increase the engine
speed to 1,000-l ,500 rpm and measure the fluid pres-
sure generated by the oil pump. If the pressure is below
specification, replace the oil pump assembly.
Oil pump fluid pressure:
7,356 kPa (75 kg/cm2, 1,067 psi)
Caution
l If the valve Is left closed for more than 15 seconds,
the fluid temperature will increase excessively and
adversely affect the oil pump.
6. Open the gauge valve fully again and increase the engine
speed to l,OOO-1,500 rpm.
7. Turn the steering wheel fully to the left and right and meas-
ure the fluid pressure generated by the gear housing. If the
pressure is below specification, replace the gear housing
assembly.
Gear housing fluid pressure:
7,356 kPa (75 kg/cm2, 1,067 psi)
Caution
l If the steering wheel is kept in the fully turned po-
sition for more than 15 seconds, the fluid tempera-
ture will rise excessively.

Tire Wear
1. Check the remaining tread.
Remaining tread
Standard tires: 1.6mm (0.063 in) min.
Snow tires: 50% of tread ’ _,I’
2. The tire should be replaced if the wear indicators are
exposed.
Inspection (Tire and Wheel)
The wheel or tire should be replaced if any crack, damage,
deformation or other problem is found.
Wheel and Tire Runout
1. Jack up the vehicle and place it on safety stands.
2. Set the probe of a dial indicator against the wheel, and meas-
ure the runout through one full revolution.
Runout:
_..’
Horizontal Aluminum wheel: 2.0 (0.079), Steel wheel: 2.5 (0.098)

driving.
TIRE ROTATION
To prolong tire life and assure uniform tire wear, rotate the tires
from every 3,000 km (1,860 miles) to every 6,000 km (3,720
miles).
Caution
l Do not include “TEMPORARY USE ONLY” spare tire
in rotation.
l Use the best tires on the front axle.
l After rotating the tires, adjust each tire to the speci-
fied air pressure. (Refer to page Q-3.)
WHEEL BALANCE ADJUSTMENT
If a wheel becomes unbalanced or if a tire is replaced or
repaired, the wheel must be rebalanced to within specification.
Maximum unbalance (at rim edge)
13 inch wheel: 11 g (0.39 oz)
14 inch wheel: 10 g (0.35 or)
Caution
l Do not use more than two balance weights on the
inner or outer side of the wheel.
l If the total weight exceeds 1OOg (3.5 oz) perslde,
rebalance after moving the tire around on the rim.
l Attach the balance weights tightly on the wheel.
l Select suitable balance weights for steel or alumi-
num alloy wheels.
l Do not use an on-car balancer on automatic trans-
axle models; it may cause transaxle damage.
