ESP MITSUBISHI LANCER EVOLUTION 2007 Service Service Manual

STEERING -On-vehicle Service37A-8
2. Move ball joint stud several times and install nut on stud.
Measure ball joint turning torque with special tool.
Standard value: 1.0 - 3.0 N·m
3. When the turning torque exceeds the standard value,
replace tie rod end.
4. When the turning torque is under the standard value,
check ball joint for end play or ratcheting. If none of these,
the joint is still serviceable.
STATIONARY STEERING EFFORT CHECK
1. With the vehicle stopped on a flat, paved surface, turn
the steering wheel to the straight ahead position.
2. Start the engine and set it to 1,000±100 r/min.
3. Attach a spring balance to the outer circumference of
the steering wheel and measure the steering force
required to turn the steering wheel from the straight ahead
position to the left and right (within a range of 0.9 turns).
Also check to be sure that there is no significant fluctuation
of the required steering force.
Standard value:
Steering effort32 N or less
Fluctuation allowance6.0 N or less
4. If the standard values are not met, check and adjust
the related parts.
CHECKING STEERING WHEEL RETURN TO
CENTRE
To make this test, conduct a road test and check as follows.
1. Make both gradual and sudden turns and check the
steering “feeling” to be sure that there is not difference
in the steering force required and the wheel return between
left and right turns.
2. At a speed of 35 km/h, turn the steering wheel 90_and
release the steering wheel after 1 or 2 seconds. If the
steering wheel then returns 70_or more, the return can
be judged to be satisfactory.
NOTE
There will be a momentary feeling or “heaviness” when
the wheel is turned quickly, but this is not abnormal. (This
is because the oil pump discharge amount is especially
apt to be insufficient during idling.)
