What are shock absorbers in a car?

A mechanical or hydraulic device used to absorb and dampen shock impulses is known as a shock absorber or damper. It accomplishes this by transforming the shock's kinetic energy into another form of energy, usually heat, which is subsequently lost. The majority of shock absorbers are dashpots (a damper that resists motion via viscous friction). For instance, the springs lessen the shocks on the body caused by a rough road surface by acting as a cushion between the axles and the body. A car's body may move excessively up and down depending on the road surface and speed. These vibratory vibrations are slowed down and diminished in intensity using shock absorbers.

Symptoms of a bad shock absorber

Symptoms of bad shock absorbers can manifest in various ways, negatively impacting your vehicle's handling, comfort, and safety. Watch out for the following signs that may indicate your shock absorber is falling:

Poor handling: Unstable vehicle, excessive bouncing, or swaying during turns due to worn shock absorbers affecting control.
Rough ride: Harsh and jarring experience even on smooth roads due to compromised shock absorption.
Increased braking distance: Worn shocks lead to longer stopping distances and reduced braking efficiency.
Nose diving: The front of the car dips noticeably during braking, impacting braking performance.
Tire wear: Uneven tire wear caused by faulty shocks due to inconsistent weight distribution.
Fluid leaks: Oil or fluid leaks around shocks indicate reduced damping ability.
Noisy suspension: Clunking, knocking, or squeaking sounds over bumps due to ineffective shock absorption.
Visible damage: Physical damage or wear to shock absorber housing affects performance.
Delayed response: The car continues to bounce after hitting a bump due to worn shocks.
Drifting or pulling: The car drifts or pulls to one side during turns due to uneven shock absorber performance.
