ASE G1 Auto Maintenance and Light RepairSuspension and SteeringEasy
A technician is performing a pre-alignment inspection. They notice that when the vehicle is pushed down and released, it continues to bounce excessively multiple times before settling. Which of the following components is most likely worn or failing?
- ABall joints
- BCoil springs
- CShock absorbers
- DSway bar end links
Show answer & explanationAnswer & explanation
Correct answer: C. Shock absorbers
Excessive bouncing after pushing down on a corner of the vehicle is a classic symptom of worn or failing shock absorbers. Shocks are responsible for damping suspension oscillations, and when they fail, the vehicle will continue to bounce multiple times.
Why the other options are wrong
- A. Worn ball joints cause clunking, popping, and steering play, not a continuous bouncing motion.
- B. Worn or broken coil springs would primarily affect ride height and spring rate, causing sagging or a harsh ride, not excessive bouncing after a single compression.
- D. Worn sway bar end links typically cause clunking noises over bumps, not excessive bouncing.
Worn Shock Absorber Symptom
Excessive, prolonged bouncing of the vehicle after hitting a bump or being manually compressed indicates worn or failing shock absorbers.
- Shocks dampen spring oscillations.
- Prevents continuous bouncing.
- Affects ride comfort and tire contact.
