ASE T5 SUSPENSION &
STEERING EXAM
Technician A says a steer axle vibration or shimmy could be caused
by steer tire or wheel issues. Technician B says replacing the front
tires/wheels from another vehicle with no vibration or shimmy is a
viable diagnostic procedure. Who is correct?
A. A only
B. B only
C. Both A and B
D. Neither A nor B - ANSWERS-Answer A is incorrect. Technician B
is also correct.
Answer B is incorrect. Technician A is also correct.
Answer C is correct. Both Technicians are correct. Steer axle
vibration or shimmy could be caused by steer tire or wheel issues,
worn steering components, or worn suspension components.
Replacing the front tires/wheels from another vehicle with no
vibration or shimmy is a viable diagnostic procedure that would
eliminate the tire/wheel assemblies as a possible source.
Answer D is incorrect. Both Technicians are correct.
During a front axle assembly inspection, a technician should check for
a twisted axle beam if any of the following conditions exist EXCEPT:
A. The difference in caster angle exceeds 0.5 degrees from side to
side.
B. The caster shims in place differ by 1 degree or more.
,C. A low-speed
shimmy exists, and there is no evidence of looseness elsewhere in the
steering system.
D. Excessive tire wear exists. - ANSWERS-Answer A is incorrect.
The maximum difference from side to side for caster is 0.5 degrees.
Any reading over 0.5 degrees would indicate that further inspection of
the front axle is necessary to determine if the axle is twisted.
Answer B is incorrect. If the caster shims that are installed vary by 1
degree or more, this would indicate that the axle may be twisted. The
technician should never try to correct a twisted axle by varying the
caster shim thickness.
Answer Cis incorrect, Low-speed shimmy with no evidence of
looseness in the steering components indicates that the front axle
might be twisted. Caster is designed into the front axle to improve
steerability, If the axle is twisted, the caster angles are opposed to
each other and would produce this symptom.
Answer D is correct, Caster is a non-tire-wearing angle, so a twisted
axle beam will not cause excessive tire wear.
During a preventive maintenance inspection, the technician finds that
one spring pin will not take grease. The first thing the technician
should do is:
A. Change the zerk fitting.
B. Remove the weight from the spring assembly.
C. Replace the spring pin and bushing.
D. Heat the spring eye. - ANSWERS-Answer A is incorrect. The first
thing that should be done is to remove the weight from the spring
assembly and try to grease the assembly in a static position. If the
,technician is still unable to grease the assembly, then the zerk fitting
should be removed and the grease passage in the pin inspected.
Answer B is correct. Any time the suspension system is being
greased, the spring assemblies should be placed in a static position.
This will allow for grease to flow around the spring pins.
Answer C is incorrect. This would be the last resort.
Answer D is incorrect. You should never heat the spring eyes. This
might change the temper in the steel allowing to bending or breakage.
Technician A says that before checking the fluid level in the power
steering reservoir, you should turn the steering wheel slowly and
completely from side to side several times to boost the fluid
temperature. Technician B says that foaming in the reservoir indicates
low fluid level or air in the system. Who is correct?
A. A only
B. Bonly
C. Both A and B
D. Neither A nor B - ANSWERS-Answer A is incorrect. Technician B
is also correct.
Answer B is incorrect. Technician A is also correct.
Answer C is correct. Both Technicians are correct. The fluid temp
should be above 175°F
before checking the fluid level. The temperature should be raised by
turning the steering wheel completely from side to side. In addition,
foaming in the oil is an indication that there is air in the system and
the fluid is aerated. This may lead to overheating and components
damage if not repaired.
Answer D is incorrect. Both Technicians are correct.
, Kingpin inclination (KPI) may be defined as:
A. The forward or rearward tilt of the kingpin at the top.
B. The tracking angle of the tires from a true straight-ahead track.
C. The inward or outward tilt of the top of the wheel when viewed
from the front of the vehicle.
D. The amount in degrees that the top of the kingpin inclines away
from vertical as viewed from the front of the vehicle. - ANSWERS-
Answer A is incorrect, Caster is defined as the forward or rearward tilt
of the kingpin at the top.
Answer B is incorrect, The tracking angle of the tires from a true
straight-ahead track is toe.
Answer C is incorrect. Camber is defined as the inward or outward tilt
of the top of the wheel when viewed from the front of the vehicle.
Answer D is correct. KPI is defined as the amount in degrees that the
top of the kingpin inclines away from a true vertical line drawn
through the center of the tire and wheel assembly as viewed from the
front of the vehicle.
Upon inspection, a technician finds one air bag blown out on a tractor
with an air ride suspension. The technician inspects the rest of the
suspension system and finds no mechanical or fatigue issues.
Technician A says that it is acceptable to replace just that air bag.
Technician B says that the axle alignment should be checked after
replacement. Who is correct?
A. A only
B. B only
