Question

A technician is checking a suspension complaint. He depresses the front bumper a few inches by hand then releases it. When the front bumper is released, it oscillates up and down about three times before coming to rest. What could be the problem?
a) Worn tires
b) Faulty steering wheel
c) Worn shock absorbers
d) Loose lug nuts

Jude Bellingham · Answer

The correct answer is:

c) Worn shock absorbers

Explanation:

Shock absorbers are responsible for controlling the oscillations of the suspension system. They dampen the up-and-down motion of the vehicle after it encounters bumps or depressions on the road.
When shock absorbers are worn out, they fail to effectively dampen the oscillations, resulting in the vehicle bouncing multiple times (in this case, three times) before coming to rest.

Why not the other options?

a) Worn tires:
- Worn tires can cause uneven handling or vibrations but do not directly affect the number of oscillations after depressing the bumper.
b) Faulty steering wheel:
- A faulty steering wheel would cause steering issues but does not relate to suspension oscillations.
d) Loose lug nuts:
- Loose lug nuts can cause wheel wobbling or vibrations, not repeated suspension oscillations.

Conclusion:

Excessive oscillations after releasing the front bumper indicate worn shock absorbers, as they are failing to stabilize the vehicle effectively.
