Quick Facts About Shocks and Struts
- Shocks absorbthe brunt of the force after a vehicle hits a pothole or bump in the road.
- Struts help keep tires aligned.
- Regularly driving too fast over speed bumps can harm your shocks and struts, among other components of your suspension system.
It’s easy to self-inspect many visible car parts on your vehicle, but it becomes more challenging when those parts, like shocks and struts, are under the vehicle. Still, your car will give you signals when they’re starting to wear down. The best way to diagnose if something seems amiss is to use your senses while you drive.
Keep reading to find out how you can maintain a comfortable ride. We’ll explain how you can tell if these two integral components of your car’s suspension system are worn out and need replacing.

What Are Shocks and Struts?
The shocks and struts are two components of your car’s suspension system. They work together to keep your vehicle stable and balanced, so it’s easier to control. The two parts jump into action when going over speed bumps and potholes, making sharp turns, and even driving in storms with strong winds.
Shocks
Shocks, also called shock absorbers, cushion much of the impact of bumps and uneven roads. Here’s how they work to keep your ride safe and comfortable:
- Takes the brunt of the force after a vehicle hits something, like a bump or pothole in the road
- Assists with stability after your car hits a pothole or speed bump, making the vehicle easier to control
- Helps keep the tires connected to the road, so even if you hit a deep crevice, the vehicle won’t swerve or tilt much afterward
Struts
Your struts work differently than shock absorbers and other suspension system parts. In addition to helping absorb some of the bumps from potholes and rough roads, struts act as a structural piece in the following ways:
- Works to connect the suspension system
- Helps tires stay aligned
- Keeps the car stabilized and on the road after hitting a bump or pothole
Signs Your Shocks and Struts Are Worn
Like every part of your car, the shocks and struts get worn out and will eventually need replacing. Car maintenance expert Gary Hardesty with Kelley Blue Book says to look for these signs that you need to get your shocks and struts inspected.
1. Bouncing Car
Shocks and struts prevent your car from bouncing after hitting a pothole, speed bump, or just driving on a rough road. When these parts don’t work, the vehicle will bounce more than usual and cause an uncomfortable ride. This is one of the most significant signs that your shocks and struts need repair.
2. Tipping or Leaning
Along with limiting any bouncing, shocks and struts stabilize a vehicle. When making sharp turns, you should still feel connected to the road. If these parts of the suspension system are not working, your car will lean to either side when making sharp turns or tip forward or backward when accelerating or braking. Either instance means it’s time for a maintenance check.
3. Leaking Fluid
Going to your car and seeing fluid underneath can ruin your day. Leaking fluid behind your tires is another sign of something wrong with your shocks and struts. Unlike under the hood, where it could be an oil leak, suspension system components could need a replacement if the leak is behind your tires.
4. Unusual Noises
If you’re driving and hear clunking sounds when you hit a pothole or speed bump, there is likely a problem with the shocks and struts. Clunking sounds tend to mean that something is breaking, and getting your vehicle inspected as soon as possible is best.
5. Tire Cupping
Your tires will wear over time, but bad shocks or struts will prematurely cause more wear and tear. Inspecting the tires for cupping will let you know it’s coming from the suspension system. If your tire doesn’t look like a circle anymore and has lumps, get your car inspected to avoid further damage to your tires.
Shocks and Struts Replacement Cost
According to Hardesty, if you need to replace your shocks and struts, the “best practice is to replace them in pairs based on front or rear.”
Repair costs can vary drastically. Also, depending on your suspension system, you may need an alignment if you replace your struts.
Hardesty states, “For a typical vehicle like a Toyota Camry, you’re looking at up to two hours of labor, and the struts will cost between $50-$224. Many luxury brands and higher tier models have active suspension systems that can go into the $1,500 to $2,600 range plus labor and calibration.”

Shocks and Struts Lifespan
Like most car systems, the lifespan of your vehicle’s shocks and struts depends on many variables like road condition, payload, and how fast you drive over speed bumps and potholes. However, they typically last from 50,000 to 100,000 miles.
