FINAL EXAM - SUSPENSION AND
STEERING QUESTIONS WITH
CORRECT ANSWERS!!
1500 psi - ANSWERHigh pressure hoses have to be used on the high pressure side
of the power steering system because pressures can reach as high as __________.
A) 200 psi
B) 750 psi
C) 2500 psi
D) 1500 psi
False - ANSWERAll power steering pumps have integral reservoirs. True or False?
all of the above are correct - ANSWERWhich of the following represent typical power
steering pressures?
A) over 750 psi when slowly maneuvering a parking lot
B) about 450 psi when cornering
C) less than 150 psi when straight ahead
D) all of the above are correct
True - ANSWERA power steering pressure switch sends a signal to the powertrain
control module, indicating higher engine speed is needed during sharp cornering at
low speeds. True or False?
Both technicians - ANSWERTechnician A says that a leaking pressure relief valve
can cause absence of power assist. Technician B says that a missing or slipping
pump drive belt can cause lack of power assist. Which technician is correct?
A) Technician A only
B) Technician B only
C) Both technicians
D) Neither technician
Technician A only - ANSWERTechnician A says that some power assist systems
use an external cooler for the power steering fluid. Technician B says that the cooler
is located in the pressure line, before the steering gear. Which technician is correct?
A) Technician A only
B) Technician B only
C) Both technicians
D) Neither technician
Technician B only - ANSWERTechnician A says that all vehicles from the same
manufacturer use exact same power steering fluid. Technician B says that some
fluids may be incompatible with system seals. Which technician is correct?
A) Technician A only
B) Technician B only
, C) Both technicians
D) Neither technician
Both technicians - ANSWERTechnician A says that lifting the vehicle and turning
steering wheel may help bleed air out of some systems. Technician B says that if this
procedure is used, the wheels should be turned from stop to stop. Which technician
is correct?
A) Technician A only
B) Technician B only
C) Both technicians
D) Neither technician
Technician B only - ANSWERA power steering pressure gauge is being used to
diagnose a system problem on a rack and pinion system. When the wheels are
turned all the way left, a pressure reading less than specification is found. When the
gauge valve is closed, the pressure reading is within specifications. Technician A
says that the pump pressure regulator is bad. Technician B says that there is a
problem in the rack assembly. Which technician is correct?
A) Technician A only
B) Technician B only
C) Both technicians
D) Neither technician
Pascal's law - ANSWERA power steering test is being performed, and the pressure
is higher than specifications with the engine running and the steering wheel
stationary in the straight ahead position. Technician A says that a restricted high
pressure line could be the cause. Technician B says that internal leakage inside the
steering gear or rack and pinion unit could be the cause. Which technician is
correct?
A) Watt's law
B) Pascal's law
C) Martin's law
D) Newton's law
Both technicians - ANSWERTechnician A says that one advantage of hydraulics
compared to a mechanical linkage is that fluid has no fixed shape. Technician B says
that hydraulics offer the opportunity to multiply the input force. Which technician is
correct?
A) Technician A only
B) Technician B only
C) Both technicians
D) Neither technician
Both technicians - ANSWERTechnician A says that the current trend is to use
remote power steering fluid reservoirs. Technician B says that using a remote
reservoir allows for a more compact power steering pump assembly. Which
technician is correct?
A) Technician A only
B) Technician B only
C) Both technicians
