How To Diagnose Bad Shocks With The Bounce Test

Is your Mazda’s ride quality feeling a bit off? Odds are one or more of your shocks has gone bad. Doing a bounce test will help you figure out if you’ve got a bad shock and pinpoint which one it is.

What Is The Bounce Test?

The bounce test doesn’t require any special tools or expertise. It’s simply bouncing each corner of your car and taking note of how many times it bounces.

Doing the bounce test takes less than 5 minutes. All you need to do is to take the following steps:

  1. Park your Mazda on a flat surface.
  2. Go to one corner of your car.
  3. In one swift motion, push down on the car as hard as you can and then let go.
  4. Observe how your car reacts.
    1. If it springs back up to at-rest height, then the shock is still good.
    2. If it bounces once, then the shock is about to go bad.
    3. If it bounces more than twice, then you need new shocks.
  5. Repeat the above steps with the rest of the corners on your car.

You Can Do A Visual Inspection Too

Did your car pass the bounce test, but you’re still suspicious that one of your shocks is either bad or about to go bad? You can do a visual inspection. Here’s how:

  1. Lift your car.
  2. Inspect the tires for any bald patches or uneven wear.
  3. Inspect the shocks for any bends, rust, oil leaks, or other damage.

If your tires or shocks look bad, then a shock replacement is in order.

Replacing your shocks is certainly something you can do at home. You just need some basic tools, OEM replacement shocks (which you can get from us at great discounted prices), and this step-by-step replacement guide.
