Shocks and Struts, what are they and what do they do

Shocks and struts are an integral part of driving comfortably. The main purpose of shocks & struts is to absorb kinetic energy (objects have kinetic energy due to being in motion, in this specific case, it’s the vehicle’s suspension system) and dissipate it as heat energy so that the cabin of the vehicle has a smooth ride as possible. Shocks have a piston & hydraulic fluid inside of them, and control bounce & sway by only letting a small amount of fluid through the piston on bounces. This slows down the piston, and in turn, the suspension. Struts perform the same basic function, but also act as structural support, unlike the shock. Because of this this, wheels with struts don’t need an upper control arm or ball joint. This compact setup is popular on front-wheel drive cars. Though you may have shocks and struts on the same car, like one kind in front & the other in the rear, you’ll never have shocks and struts on the same wheel.

“So how do I know if I need new ones?”

The basic signs usually are one (or multiple) of these:

  • Poor steering & handling
  • Noise coming from the general area of the shocks and struts
  • Tire wear that an alignment cannot fix
  • The vehicle sways & bounces “like a boat”
  • The vehicle leaks fluids onto the ground that clearly aren’t coming from the engine or transmission.
  • visible damage to the shocks & struts such as dings or dents.

Please note that, while these symptoms can be signs of bad shocks and struts, every vehicle is different and more than one issue can cause some of the above listed symptoms. To avoid unnecessary spending, please have diagnostic work done by a professional.
