Chapter 75 ASE Questions

All of the following are functions of an automotive suspension system EXCEPT:

• helps provide a smooth ride for passengers.

• keeps tires in firm contact with the road

• allows the front wheels to turn from side to side for steering.

• allows the body to tilt and squat when accelerating or heavily loaded.

Technician A says an automotive suspension system works with the steering system to help keep the wheels in correct alignment. Technician B says an automotive suspension system works independently of the steering system and has no effect on wheel alignment. Who is right?

• A

• B

• Both

• Neither

All of the following are basic components of an automotive suspension system EXCEPT:

• control arm.

• steering knuckle.

• internal control shaft.

• shock absorber.

Technician A says an independent suspension system has both the right and left wheels attached to the same solid axle. Technician B says a nonindependent suspension system has both the right and left wheels attached to the same solid axle. Who is right?

• A

• B

• Both

• Neither

Which of the following statements regarding vehicle lateral acceleration is false?

• It is measured in units or gravity, or g-force

• The average passenger vehicles attains a lateral acceleration measurement of 5.0–6.0 Gs

• Independent suspension systems generally obtain higher lateral acceleration than nonindependent designs

• It is the amount of frictional side force a vehicle can handle before its tires lose traction and skid in a sharp turn

Technician A says a leaf spring can be constructed of one or more flat strips of spring steel, fiberglass, or carbon fiber. Technician B says a torsion bar fastens to the vehicle’s body or frame and to the suspension system control arm. Who is right?

• A

• B

• Both

• Neither

Technician A says a suspension system’s control arm fastens the steering knuckle to the shock absorber. Technician B says the control arm fastens the steering knuckle to the vehicle body or frame. Who is right?

• A

• B

• Both

• Neither

Technician A says a ball joint in an automotive suspension system allows control arm and steering knuckle movement. Technician B says a nut is used on the end of a ball joint stud to increase the space between the control arm and steering knuckle for better steering response. Who is right?

• A

• B

• Both

• Neither

Technician A says due to its characteristics, hydraulic oil is the only substance that can safely be used in automotive shock absorbers. Technician B says increasing the distance of shock absorber compression and extension improves suspension performance. Who is right?

• A

• B

• Both

• Neither

Technician A says an automotive strut assembly normally consists of a shock absorber, a coil spring, and an upper damper unit. Technician B says strut assemblies are installed only on rear axles because they are incompatible with automotive steering systems. Who is right?

• A
