Shocks and struts keep your tires pressed against the road and stop the car from bouncing after every bump. When they wear out, you may notice a floaty or bouncy ride, the nose dipping hard when you brake, more body lean in turns, fluid on the shock body, or tires wearing in uneven patches. Hillside Auto Clinic at 26122 Western Ave, Lomita, CA 90717 can inspect your suspension and tell you what's worn; call (310) 956-5794 or schedule.
What shocks and struts do
Your springs hold the car up and absorb bumps. Shocks and struts control how fast those springs compress and rebound, so the car settles quickly instead of bouncing up and down. That keeps the tires in steady contact with the road, which is what gives you grip for steering, braking, and cornering.
A shock absorber is a damper only. A strut is a damper built into a structural part of the suspension, often with the spring mounted around it, and on many cars it also affects wheel alignment. Many cars have struts in front and shocks in back, but it varies by vehicle.
Why they wear out
Shocks and struts wear gradually, so the change is easy to miss when you drive the same car every day. Seals and internal valves wear with use, and fluid can leak out. Rough roads, potholes, speed bumps, heavy loads, and towing all add wear. The rubber mounts and bushings around them can also crack or break down with age.
There isn't one mileage number that fits every car. Your owner's manual or maintenance schedule may list inspection intervals, and having the suspension looked at during routine service is a simple way to catch wear early.
Signs your shocks or struts may be worn
- A bouncy or floaty ride, where the car keeps moving up and down after a dip or bump.
- Nose diving when you brake, or the rear squatting when you accelerate.
- More body roll or sway in turns, lane changes, or windy conditions on the freeway.
- Clunking or knocking over bumps, which can also point to worn mounts or other suspension parts.
- Oily fluid on the outside of a shock or strut body.
- Uneven or cupped tire wear, with scalloped dips around the tread.
- The car sits lower at one corner than the others.
- Steering that feels vague or less stable than it used to.
Some of these signs overlap with other problems, like worn ball joints, tie rod ends, or alignment issues, so an inspection is the best way to know what's actually causing them.
Why it matters for safety
Worn shocks and struts aren't just about comfort. When tires bounce or lose steady contact with the road, the car can take longer to stop, feel less stable in emergency maneuvers, and be harder to control on uneven pavement or in the rain. If your car handles differently than it used to, it's worth having it checked.
What a suspension inspection covers
A technician will typically road test the car, look for leaks and damage on the shocks and struts, check the mounts, bushings, and springs, and look at tire wear for clues. They'll also check related parts like ball joints and tie rod ends, since those can cause similar symptoms.
Shocks and struts are usually replaced in pairs on the same axle so both sides respond the same way. Because struts can affect alignment on many cars, an alignment check is often recommended after strut replacement.
Simple ways to stay ahead of it
- Pay attention to how the car rides over the same bumps you drive every day.
- Look at your tires for uneven or patchy wear when you check the air pressure.
- Slow down for potholes and speed bumps when you can.
- Ask for a suspension check during your next oil change or tire rotation.

FAQ
How do I know if my shocks or struts are bad?
Common signs are a bouncy ride, nose diving when braking, extra body roll in turns, fluid leaking from the shock body, and uneven tire wear. An inspection can confirm whether the shocks and struts or other parts are the cause.
What's the difference between shocks and struts?
A shock absorber only dampens movement. A strut does that too, but it's also a structural part of the suspension and often holds the spring. Your car may have one, the other, or both.
Can I drive with worn shocks or struts?
You can usually still drive the car, but worn shocks and struts can make it harder to stop and control, especially in an emergency or on rough roads. It's best to have them checked soon.
Should shocks and struts be replaced in pairs?
Usually, yes. Replacing both sides of the same axle keeps the car balanced so it handles and brakes evenly.
Do I need an alignment after replacing struts?
On many cars, yes. Struts are often part of how the wheel is positioned, so an alignment check after replacement helps keep the car tracking straight and protects your tires.
