One way to tell if you have shocks or struts is knowing what each kind of absorber looks like. Rather than looking for coil springs
Coil spring
A coil spring, also known as a helical spring, is a mechanical device which is typically used to store energy and subsequently release it, to absorb shock, or to maintain a force between contacting surfaces. They are made of an elastic material formed into the shape of a helix which returns to its natural length when unloaded.

Is it bad to drive with bad struts?
Bad struts while driving can cause the wheels to either break down or cause a flat tire. Wheels and tires are part of the suspension system. It will destroy your wheels and can cause a huge accident if you are driving with bad struts because sometimes while you are driving and the tires break down, you can crash in some barrier or another ...
How do you identify struts?
On a Windows system:Open file explorer, search for struts*. jar.Open struts-core. jar with a unzip tool (e.g. IZArc2Go)Open META-INF folder and open MANIFEST. MF file with a text editor.There you will find Specification-Version: with the version number.
What are the different types of struts?
Type of strut: The three main types of struts are gas, coilover, pneumatic – all of which operate under the principle that reducing the shock of driving should occur by dampening the effect of springs, oil and gas together.
Are struts car specific?
Struts are typically installed in conjunction with the front wheels, but depending on a vehicle's setup and driveline, they can also be mounted at the rear wheels. Just as there are different types of cars, there are different types of struts.
How do I know if I have struts or shocks?
Look underneath your vehicle. If your vehicle has shocks, you will likely find them mounted vertically behind the tires. In many cases, shocks will look like a spring or pump. Struts, on the other hand, are usually mounted horizontally and will appear as an extension of the wheel.
Where is the part number on a strut?
Locate the OEM part number(s) on the strut you wish to replace and make a note of them. These are usually located on the thicker part of the strut body and are generally a combination of letters, digits and dashes.
Will new struts improve my ride?
A thorough inspection should uncover what parts, if any, actually need replacement. The springs in your vehicle's suspension do most of the shock damping. The shocks and struts improve the ride and reduce the bouncing caused by springs compressing and releasing so you don't go boing-boing down the road.
Should you replace all 4 struts at once?
Shocks and struts should always be replaced in pairs (front axle or rear axle), and it's even better to replace the shocks/struts on all four wheels at one time. This helps maintain reliable handling and a consistent response on both sides of the vehicle.
How long do struts last on a car?
On average, if your car has been “babied,” you can expect your shocks/struts to last about 10 years. If you have really used your car like a workhorse, 5 years is probably all you can expect. This means that for the average driver, 7 or 8 years is the maximum life expectancy of most shocks and struts.
Are struts hard to replace?
The good news is, some repairs are easy to do at home. Like replacing shocks and struts. It's not a job that you should attempt if you're not familiar working with vehicles, but with a little training and experience, you'll be ready to tackle the job.
What will bad struts do to a car?
Increased wear on other suspension parts – Worn shocks and struts can have a negative effect on related steering, braking, and suspension components. As the shocks or struts wear, they allow more suspension movement, meaning that other steering, braking and suspension components can suffer the same effects.

What is the difference between a strut and a coilover?
Coilovers are struts where the spring coils around and over all the way up to the top. The only difference here is that coilovers generally offer more adjustability in the way of ride height, dampening, and also allow the user to switch out springs for a more-custom spring rate.
How many struts are on a car?
All cars have four struts/shocks; one at each wheel. Most modern cars and SUVs have struts in the front suspension and shocks or struts in the back.

How to tell if struts are failing?
Some signs of failing shocks or struts include taking potholes and speed bumps especially hard, a front-end nose-dive when braking, and any signs of leaking hydraulic shock fluid.
What is a strut in a car?
A strut acts as a pivot point for the steering system and includes integrated coil springs. Because a strut is such an integral part of your suspension system, without it your vehicle would fall straight down to the ground. This is not necessarily the case with shocks.
What do shocks and struts do?
Both shocks and struts work to dampen the movement of your wheels to inhibit any swinging or bouncing. Although these components perform the same task, you can never replace one for the other. Whether it’s suspension for a Toyota Camry or for a Chevy Silverado, each of your vehicle’s wheels are designed to work with a shock or a strut, and it will have to stay that way.
What is a shock absorber?
Shocks. While a shock is also designed to absorb and recover from bumps on the road, this component does not shoulder the weight of the vehicle. A shock houses a piston within a sealed tube and is usually filled with gas or liquid which works as a buffer against bumps. In principle, a shock absorber works the same as an oil pump.
How to tell what your car has?
While it can vary from model to model, the best way to determine what your vehicle has is by general appearance. Shocks are more likely to look like a spring or a pumping mechanism and are almost always installed standing upright. Struts on the underhand tend to be installed horizontally and can be more difficult to see.
Do you have struts on your front wheels?
However, you may have struts on your front wheels and shocks on your rear wheels. To determine what combination of shocks and struts you have on your vehicle, first we need to learn a bit more about what they are.
Do struts have to be horizontal?
Struts on the underhand tend to be installed horizontally and can be more difficult to see. Once you locate them you’ll know, because struts appear to be extensions of the wheels themselves and are clearly essential components for keeping your axles off the ground.
How do shocks and struts work?
Both shocks and struts work as part of the suspension system, where they help to reduce bounce and oscillation.
Where are the shocks and suspension located?
If you don’t, the most sure-fire way is to check under the carriage. Both shocks and suspensions will be located near the tires. Shocks will be vertical and resemble a pneumatic pump. Struts are horizontal and look to be just extensions of the wheels.
Do cars have shocks?
Typically, this means your car will have one or the other. Although it is important to note, some vehicles have both: shocks in the front and struts in the rear or vice versa.
Is a strut bad for your car?
If you think your shocks or struts are damaged or are not functioning properly, then that’s something you need to have inspected. A malfunctioning shock or strut is not only bad for your car’s health, it’s dangerous. Your suspension keeps your carriage from sliding all around, and if malfunctioning, it could result in a serious accident.
How to tell if struts are bad?
Another tell-tale sign is when you take a turn or hit a pothole you didn’t see. If you feel the vehicle sway or if it feels as if it just isn’t stable, chances are that the struts are bad.
How Long Do Shocks/Struts Last?
This depends on many factors. You can think of shocks or struts like tennis shoes. If you only wear them on the weekends to go to the mall, they will last far longer than someone who wears them daily, rides a skateboard, and uses their shoes as brakes fairly frequently!
Why don't people replace shocks?
Some people never replace their shocks or struts because they honestly don’t realize that they are worn out. How can you tell for certain? The following are 5 sure-fire signs.
What does a shock absorber look like?
Shock absorbers, or shocks for short, look similar to the shocks you see on the front wheels of bicycles. Struts are encased inside a coil spring and are much more complicated designs.
What color is the fluid on a shock?
If you get a flashlight, you can take a look at your shocks and struts. Do you see fluid (usually brown in color) leaking down onto the bottom part of the shock or strut? While you might have a leak elsewhere that is splashing on the shock, this has a different look to it. This fluid leak should come straight down and not have a splash of fluid on one side only.
How to tell if your car is bouncing?
One way to check is to push or stand on the bumper and bounce up and down a few times, then hop off (be careful not to fall!). The car should bounce once more then stop.
Why does my steering wheel vibrate?
While a vibration felt in the steering wheel is sometimes due to unbalanced wheels , it can also mean worn out struts.
What is a strut in a suspension?
In addition to absorbing bumps and jolts, struts also provide structural support. They take the place of the upper control arm and upper ball joint that are required in conventional suspensions.
What Do Shocks & Struts Do?
Shocks and struts are a vital part of your vehicle’s suspension system. They work with the other components in your suspension system to ensure a stable, comfortable ride.
What are shocks in a car?
Shocks are individual components of the suspension that help the coil springs absorb the impact of the road. Without shocks, the vehicle would bounce out of control! They help keep the tires in contact with the road instead of bouncing up in the air after a bump.
Why do you need to replace shocks?
Replacing your shocks and struts when they are worn down will prevent damage to other vehicle components like the tires and suspension, and it is also critical for driving safety! Today’s vehicles have an array of safety systems designed to help improve handling and stability and prevent accidents.
Why do my tires have wavy dips?
Uneven treadwear. Cupping—scalloped, wavy dips on the tire tread—is a tell-tale sign of worn shocks and struts. It is caused by the tires not being held firmly to the road as you drive. Cupping shortens the usable life of your tires and diminishes handling and stopping power. 4.
How often do shocks wear out?
Generally, shocks and struts wear out every 50,000-100,000 miles. If you’re a more aggressive driver and/or frequently drive on rough roads, they will wear out faster. Shocks and struts don’t go out all at once; they deteriorate slowly over time.
How to tell if your shocks are bad?
A rough, bumpy ride is one of the easiest symptoms to notice. 2. Leaking fluid . Leaked fluid on the exterior of the shocks/struts is a sign that something is wrong. If the shock absorbers do not have enough hydraulic fluid, they won’t be able to absorb impacts as you drive.
How to tell if strut is bad?
Unstable Car. Another sign of a bad front strut is a floating front end. A floating front end can cause your vehicle to swing to and fro to one side. At high speeds, this can cause problems not only for you but for others as well. If you experience such symptoms, you should first have the alignment of your car checked.
Why do struts make a noise when you hit a bump?
Knocking Noises on Bumps. The front struts carry the entire weight of the car. They are directly connected to the chassis via the wheel assembly. For this reason, the struts absorb any shaking when you hit a bump in your car’s road surface and leave you feeling nothing.
What does a bad strut do to a car?
A bad strut can cause an bumpy ride and reduce the car's drivability. Here's how to tell if your car has a bad strut
What happens if a strut fails?
If a strut fails, you will inevitably hear a knocking sound when you hit a bump. This noise can increase over time as the strut’s internal components, such as the shock absorbers and bushings, also wear out. If you hear this strange noise near the front of your car, it is time to have a professional examination.
Why is my shock absorber bumpy?
However, a bumpy ride is not always an indication of shock absorber failure. It can also be caused by the failure of other suspension components such as bushings . For this reason, it is always better to have an inspection carried out by a mechanic you trust. He can decide on the best course of action.
What to do if your car alignment is out of shape?
If you experience such symptoms, you should first have the alignment of your car checked. If the alignment is a little out of shape, have it fixed correctly. Otherwise, you could take your car to the nearest mechanic and get an estimate for a replacement.
What to do if you hear a strange noise in front of your car?
If you hear this strange noise near the front of your car, it is time to have a professional examination. A professional can decide whether you need a replacement or not.
What are the struts on a car?
CARS.COM — Your car’s struts are a vital part of its suspension system. They are structural in nature, and they are mounted to the top of the car’s chassis. Struts come down through the chassis and provide a location to mount the coil spring, which maintains the car’s height. Both the front struts and rear struts are extremely important.
Why are my struts leaking?
The struts could be leaking or the rubber bushings that act like cartilage protecting a joint might have worn, allowing metal-to-metal contact. The strut assembly may have become damaged due to rust or age, as well. On the other hand, the problem could be elsewhere.
Why are shock absorbers misleading?
“Shock absorber” is a misleading term because the springs actually absorb the road shocks. The struts limit the resulting bouncing caused by the springs compressing and releasing.
Do struts need to be replaced?
Struts don’t need to be replaced unless your vehicle is bouncing like it’s on a pogo stick or bottoms out in potholes and over railroad tracks — or unless a mechanic finds that they’re leaking fluid or have been damaged. In some climates, they can also rust.
Do struts wear out?
The more you carry heavy loads or drive on truly rough roads, the faster the struts will wear, but they often last the life of a vehicle if you don’t abuse them. Don’t automatically ask your mechanic for new struts when you sense a problem; instead, explain what you’re experiencing and let an expert figure out if worn struts are causing problems with your car. You could have a different suspension problem, or your vehicle may be suffering from something else entirely.
