Exam 5: Shock Absorbers and Struts

Technician A says oil flow calibration in a shock absorber or strut must be in relation to the deflection rate of the spring. Technician B says oil flow calibration in a shock absorber or strut must be in relation to the length of the lower control arm. Who is correct?

MacPherson strut replacement is being discussed. Technician A says that the lower rear strut hole may be elongated to allow for a camber adjustment on some vehicles. Technician B says that the lower rear strut hole may be elongated to allow for easier installation on difficult locations. Who is correct?

It is not necessary to support any suspension component when replacing a shock absorber or strut.

Load leveling shock absorbers/struts may be equipped with what?

Gas-filled shock absorbers should extend when disconnected.

On some vehicles, before a strut is removed from the steering knuckle what should be marked in relation to the strut mounting to avoid major alignment error?

Compared to a conventional shock absorber, a heavy duty s hock absorber has:

Technician A says when a front strut is fully compressed, the spring bumper on the strut rod provides a cushioning action. Technician B says the top of the strut housing should contact the spring bumper on the strut rod before the coils in the spring contact each other. Who is correct?

Struts perform the same function as shock absorbers; however, struts may also support the top of the steering knuckle.

All of these statements about gas-filled shock absorbers  are true EXCEPT:

What is the role of the shock absorber?

Shock absorbers control spring action.

All of the following statements about gas-filled shock absorbers and struts are true EXCEPT:

Explain the purpose of the nitrogen charge in shock absorbers and struts.

What does a single tube design in a heavy-duty shock absorber prevent?

Technician A says shock absorbers control spring action. Technician B says harsh riding may be caused by worn-out shock absorbers. Who is correct?

Describe the spring action during wheel jounce and rebound.

The valve in most shock absorbers/struts is designed to vary the oil flow through the valve in relation to what?

A worn shock absorber or strut may increase braking distance.

Describe oil movement in a shock absorber or strut during wheel jounce.
