DIY Shock or strut replacement

Replace Your Shocks and Struts Every 100,000 Km or 60,000 miles.

You’ve probably figured out how to tell when your brakes or tires are wearing out. Shocks and struts are just as critical and they’re much more difficult to inspect. This can be frustrating, because your shocks and struts are safety-critical components that wear out over time, just as your brakes and tires do. They should be checked regularly to keep your vehicle riding smooth and safe and to keep you and your passengers comfortable.

When is it time for new shocks or struts?

This simple ‘Worn Shocks and Struts Inspection’ demonstrates how these safety-critical components can affect the way your vehicle performs in three critical areas: steering, handling and ride comfort.


Why They Fail: Shocks and struts have seals that help contain the gas or liquid that allows these components to do their job. As the seals wear out, this gas or liquid leaks out and the shocks and struts lose their ability to keep your tires in constant contact with the road.

When this happens, the tires wear out faster. Worn shocks and struts can also contribute to quicker wear and tear on your steering and accelerate the wear of your suspension parts … the ball joints, steering linkage, springs and C.V. joints.


Quick Tips: When you’re inspecting your vehicle, always look for uneven wear patterns on your tires. “Cupping” is an uneven pattern commonly associated with worn out shocks/struts and when you find it, it’s a safe bet that your shocks and struts need some attention.

When you notice that your vehicle’s front end dips and bounces excessively during sudden stops, this is another sign that your shocks or struts may need replacing.


Worn Shocks & Struts Warning Signs:

  • Fluid leaking out of the shock or strut body
  • Shock or strut bodies are dented or damaged
  • Mounts or bushings are broken or worn
  • Cupped, uneven tire wear
  • Vehicle sways or leans on turns
  • Vehicle “nose dives” when you apply the brakes
  • Excessive bouncing after hitting a road bump
  • Harsh, bumpy or shaky ride
  • Steering is stiff or makes noise
  • Rear end squats when accelerating
  • Vehicle “bottoms out” (with a thump) on bumps
