Shock Absorber

What it does
A shock absorber is a hydraulic cylinder that turns the bouncing energy from bumps into heat. Picture a bicycle pump filled with thick oil — push it fast and it resists. That resistance is what keeps your tire glued to the road after a bump instead of bouncing like a basketball. A worn shock loses that resistance — the oil has leaked or broken down — and your car bounces freely. Every bump becomes multiple bounces, handling feels sloppy, and the car dives forward hard when you brake.

Frequently asked questions
How do I know if my shocks are bad without a mechanic?
The bounce test: push down hard on each corner of the car and let go. A car with good shocks rebounds once and stops. Bad shocks let the car bounce two or more times before settling. Also check for oil leaking down the outside of the shock body — that's a dead giveaway.
Should I replace all four shocks at once?
Replace in pairs (both fronts or both rears at the same time) so handling is balanced side-to-side. If fronts are worn, rears are usually close behind — replacing all four is often cost-effective and avoids a return trip to the shop.
What is the difference between a shock and a strut?
A strut is a structural part of the suspension — it holds the wheel in place AND absorbs bumps. A shock absorber is a separate damper that only handles the bump-absorption role. Many modern cars use struts up front and shocks in the rear.
How long do shock absorbers last?
Typically 50,000–100,000 miles, but it depends heavily on road conditions. Lots of potholes or unpaved roads accelerate wear dramatically. If your car feels floaty or nose-dives when braking, have the shocks inspected.
