sure.
Freeplay should not exceed the maximum.
Maximum freeplay: 30 mm (1.18 in.)
2. CHECK STEERING EFFORT
(a) Center the steering wheel.
(b) Remove the steering wheel pad. (See page SR±11)
(c) Start the engine and run it at idle.
(d) Measure the steering effort in both directions.
Reference: 7 N´m (70 kgf´cm, 61 in.´lbf)
HINT:
Be sure to consider the tire type, pressure and contact surface
before making your diagnosis.
(e) Disconnect the PPS solenoid connector.
(f) Measure the steering effort in both directions and check
that the steering effort exceeds the reference value in (d),
and that the power assist is operating. If steering effort is
not heavier than (d), check the solenoid.
HINT:
Take the tire type, pressure and contact surface into consider-
ation before making your diagnosis.
(g) Connect the connector.

4. CHECK WHEEL BEARING LOOSENESS
(a) Check the backlash in the bearing shaft direction.
Maximum: 0.05 mm (0.0020 in.)
(b) Check the axle hub deviation.
Maximum: 0.05 mm (0.0020 in.)
5. CHECK FRONT SUSPENSION FOR LOOSENESS
6. CHECK STEERING LINKAGE FOR LOOSENESS
7. CHECK BALL JOINT FOR LOOSENESS AND
EXCESSIVE PLAY (See page SA±34)
8. CHECK SHOCK ABSORBER WORKS PROPERLY
Check for oil leak
Check mounting bushings for wear
