Question 1

A rear subframe includes the engine, transaxle, and steering/suspension system.

Accepted Answer

A) True 
 B)False

Question 2

What is the purpose of compression damping?

Accepted Answer

Compression damping is used to control the relatively light unsprung weight of the tires, wheels, and brakes. It works with the spring to keep the tire in contact with the road surface.

Question 3

Why are shock absorbers referred to as double-acting?

Accepted Answer

Shock absorbers are ...

Question 4

Independent suspension systems have more unsprung weight than rigid axle suspensions.

Accepted Answer

A) True 
 B)False

Question 5

A(n) ____________________ shock usually has the reserve chamber in the same column as the working piston.

Accepted Answer

The answer of A(n) ____________________ shock usually has the reserve...

Question 6

Which of the following is LEAST-Likely a component of the suspension system?

Accepted Answer

A)  Springs
B)  Shock absorbers
C)  Bearings
D)  Control armsE) C) and D)
F) A) and D)

Question 7

What is the purpose of a stabilizer bar?

Accepted Answer

A stabilizer bar, also called a sway bar or an anti-roll bar, is used on the front or rear of many suspensions. It connects the lower control arms on both sides of the vehicle together, reducing sway and functioning as a spring when the car leans to one side. When both tires move up or down an equal amount, the stabilizer simply rotates in its bushings. If one of the wheels moves up, the bar twists as it tries to move the other wheel along with it.

Question 8

Torsion bars are made of heat-treated alloy steel with a hex head or splines at each end.

Accepted Answer

A) True 
 B)False

Question 9

The term MOST-Likely used to describe the event that occurs when hydraulic fluid becomes mixed with air is:

Accepted Answer

A)  aeration
B)  squat
C)  active suspension
D)  gas shockE) None of the above
F) B) and D)

Question 10

All of the following statements are true EXCEPT:

Accepted Answer

A)  double wishbone suspensions have improved directional stability and steering control.
B)  a Macpherson strut has an upper control arm and upper ball joint.
C)  double wishbone suspensions react to body roll more easily than any other type of independent suspension.
D)  multilink suspensions allow the designer more options in suspension tuning.E) A) and B)
F) A) and D)

Question 11

While having a discussion, Technician A says that SLA suspensions maintain precise wheel position under all driving conditions. Technician B says that they can have a large amount of vertical travel without scrub. Who is correct?

Accepted Answer

A)  A only
B)  B only
C)  Both A and B
D)  Neither A nor BE) B) and D)
F) All of the above

Question 12

Some trucks have one or more ____________________ leaves that do not work until the other leaves have deflected enough under load to allow them to come into contact.

Accepted Answer

overload

Question 13

A(n) ____________________ allows motion in two directions, moving with the same up-and-down motion as the bushings on the other end of the control arm.

Accepted Answer

The answer of A(n) ____________________ allows motion in two directions,...

Question 14

Which of the following statements is LEAST-Likely true?

Accepted Answer

A)  During hard acceleration, the front of the vehicle lifts and the rear lowers.This is called squat.
B)  An active suspension system works with sensors, a computer, and activators to solve problems.
C)  An active suspension requires conventional shock absorbers or springs.
D)  Sensors provide the computer with necessary information regarding extension and compression of each actuator and how heavily the vehicle is loaded.E) C) and D)
F) B) and C)

Question 15

Some vehicles made since the early 1980s have used composite springs made of reinforced fiberglass or graphite-reinforced plastic.

Accepted Answer

A) True 
 B)False

Question 16

All of the following statements are true EXCEPT:

Accepted Answer

A)  gas shocks were invented to control aeration, cavitation, and foaming of the hydraulic fluid.
B)  pressurizing the oil column in the shock absorber keeps the bubbles in the solution.
C)  some gas shocks have a pressurized gas-filled cell.
D)  twin-tube gas shocks are pressurized with nitrogen gas at 30-90 psi, depending on the manufacturer and the damping force desired.E) B) and C)
F) A) and C)

Question 17

The ____ is the most common spring type used in passenger cars.

Accepted Answer

A)  coil spring
B)  jounce
C)  leaf spring
D)  wishboneE) C) and D)
F) None of the above

Question 18

Springs support the load of the vehicle, absorbing the up-and-down motion of the wheels that would normally be transmitted directly to the frame and body.

Accepted Answer

A) True 
 B)False

Question 19

Normal suspension systems are MOST-Likely referred to as:

Accepted Answer

A)  shackles
B)  passive systems
C)  load carriers
D)  adaptive systemsE) A) and B)
F) A) and C)

Question 20

Rather than compressing, a(n)  ____ is a straight rod that twists.

Accepted Answer

A)  ball joint
B)  shock absorber
C)  shackle
D)  torsion bar springE) All of the above
F) None of the above
