Question

Difficulty: MediumBasic Maintenance and Daily Checks

To check for worn shock absorbers on a car, you should push down firmly on the bodywork above each wheel; if the vehicle continues to bounce repeatedly after release rather than settling immediately, the shock absorbers are likely defective.

Answer: Answer

Answer

True. A vehicle that continues to bounce after being pushed down and released has worn or defective shock absorbers.
The statement is true because the manual bounce test is an established, practical method for identifying worn shock absorbers. When you apply firm downward pressure above each wheel and release, a roadworthy vehicle will rebound and settle almost immediately. If the vehicle continues to bounce or rock, the damping mechanism is degraded and requires maintenance.

Step-by-Step Solution

1
Identify the primary function of a vehicle's shock absorbers within the suspension system.
Shock absorbers control and dampen the rebound movement of suspension springs to keep tyres firmly in contact with the road.
Understanding component function helps determine what physical symptoms indicate failure.
2
Evaluate the physical outcome of the manual bounce test on vehicle bodywork.
Effective shock absorbers stop rebound movement almost instantly, whereas worn shock absorbers allow the vehicle body to bounce repeatedly.
A lack of hydraulic or gas damping resistance allows the suspension springs to oscillate freely.
3
Determine whether the provided statement accurately reflects this diagnostic procedure.
The statement correctly describes the test and its diagnostic symptom, confirming that the statement is true.
The description aligns directly with standard DVSA vehicle maintenance guidelines.
