When driving in an area of desert, you might observe that your vehicle shakes whenever you hit a bump. It’s because your car is vibrating and could cause damage if you do not know why. What is it that causes your car to shake? What is the reason for it?
Many believe top-quality shocks are essential to ensure a safe and comfortable ride. However, poor shocks can cause unpleasant vibrations, affecting energy consumption by up to 10% and reducing the useful load.
Damaged or worn-out shocks could result in more than just a sour ride. There could be serious safety issues. The shocks in your vehicle help ensure an enjoyable drive, as well as help maintain control over the vehicle. Be aware of any problems in your vehicle. Keep an eye out for the following signs of bad shocks.

How do shocks work in a car?
A car’s suspension system depends heavily on shock absorbers to ensure that your tires are connected to the road by decreasing the impact of bumps on the road. In turn, the hydraulic pressure reduces bumps and absorbs road vibrations.
- By converting the kinetic energy of springs to heat energy, shock absorbers reduce their movement. It is why hydraulic fluid is produced.
- When your car’s suspension moves it, a piston moves through the cylinders filled with oil. When the vehicle’s suspension moves up & down, the piston, small holes inside the head of the piston allow the fluid to get into.
- A tiny quantity of liquid is utilised every time the piston is moved, slows the suspension’s motion, and dampens the spring’s rebound and compression.
- Additionally, they are velocity-sensitive and can only absorb movement as the vehicle moves. Therefore, the more quickly the springs move and the greater resistance the shock absorber will provide.
How Do I Know If My Rear Shocks Are Bad?
It is easy to tell if your rear shocks are faulty by driving over an obstacle and watching how your car reacts. For example, if it bounces repeatedly, you likely need to replace the shocks.
The front of a car usually has to be aligned every two years. Therefore, it is likely to show tire wear patterns when it’s not aligned.
In an SUV or pickup truck, the rear tires may be in disarray even when running unevenly. In addition, rear suspensions are generally independent and don’t have a toe-in or toe-out adjustment on the front. Instead, the rear suspensions adjust to castor and camber – occasionally, in trucks, they’ll have adjustable shackles that allow you to adjust the pinion angle.
Even with all this, however, you’re not likely to receive an alignment printout for the rear end as you would for the front.
Castor and camber aren’t adjustable for most vehicles unless they change from the stock setting. If your tires don’t display any uneven wear, then an alignment shop might be unable to adjust the angles. However, I’d like them to alter the tips if they aren’t in the right place.
Can Bad Struts Cause Vibration At High Speeds?
A damaged strut can cause a vibration when driving at high speeds, and however, usually, it’s not the strut itself that is poor. Instead, worn-out tires are the most frequent cause of a sound felt at high speeds (60 miles per hour or more).
If tires wear, the tread pattern becomes uneven. The result is that the tires exhibit what’s known as a “hop.” The hop can cause an out-of-balance condition, perceived as a sound through the seat and steering wheel.
If you install two new tires on one side of your car and take it for a drive, you’d be able to feel the sway on the wheels with older tires.
Another reason for vibrations during high speed is the bent front wheel. A bent wheel may result from hitting a curb or pothole, but it won’t cause problems until it becomes hot while driving along the road.

How Do You Check Rear Shocks By Hand?
It’s easy to test the shocks manually, bounce the car a few times, and observe how quickly the car bounces back. If you’d like to know more about the issue, raise the rear axle and take off the tires to observe them more clearly. Next, shake or tap the shock to see whether there’s any play within the shock. If there’s any play, it’s time for you to replace the shocks.
It is also possible to check for leaks in your shocks. Leaks of oil in the shock absorber usually indicate that it’s time to replace the shocks. While you’re there, you can try shaking the tire while keeping your hand on the top part of the shock absorber. If there’s movement in one of the bearings, you’ll notice it in the vibrations of the tire.
Do Rear Shocks Make Noise?
Yes, they are. If you hear a sound that seems like metal scraping against metal, that’s the shock. It will not only make an ominous sound. However, it could cause damage to your vehicle in the future. If you’re having issues with your rear shocks and require repairs, make your appointment to see a qualified.
When To Replace Your Rear Shocks
Numerous indicators indicate that your rear suspension needs replacement. Perhaps you know that your vehicle is not as stable as it used to be when you drive on cracks or bumps on the road. Maybe you’ve noticed that your car is sliding more than usual. All of these are signs that your rear suspension needs to be replaced.
If you observe any of these signs or when it’s been some time since your last repair, set up your appointment to see a specialist.
What Is A Clunking Sound?
Clunking sounds. These are the more frequent sounds that cars can emit and are usually easy to identify. A clunky sound could mean various possibilities. However, the most likely explanation is you’ve tripped over an object, and your tire has thrown rocks onto the undercarriage. Sometimes it’s not such a big problem.
For example, if enough force throws at rocks may be able to bounce off without injury. In other instances, stones may scratch away parts of your vehicle’s undercarriage and cause harm to shocks and struts. Examine your vehicle for damages If you hear a grinding sound. If nothing is evident, you might need to bring your vehicle to a mechanic, so they can look at the suspension and other parts that may be damaged due to rocks or other debris on the road.

Why Is My Car Rattling At The Back?
Various factors could cause noises rattling from the back of your vehicle. It is crucial to determine precisely where the sound is. If you’re sure it’s emanating from the rear and not under the vehicle, check the trunk compartment for luggage or the trunk. If there’s something loose, like a tire iron or jack handle, then tighten it up. Also, check for spare tires and ensure they’re securely in place if they’re in the area.
If there is a hitch at your car’s rear, ensure that the pins are all in place and secured. If not, you should move to the location where the exhaust pipe runs into the vehicle’s interior. Verify that no furniture or other objects are snagged against the pipe. One of the most common car issues is loose suspension components that cause noises like rattles, vibrations, clunks and squeaks, and shimmy issues. A few of these concerns relate to safety and noise issues.
When Replacing Shocks What Else Should Be Replaced?
You’re doing yourself a disservice by putting off replacing your struts and suspensions. As a result, the car will be less secure, especially on bumps or uneven pavement.
You wouldn’t want to drive a car with a flat tire, wouldn’t you? Likewise, why would you want to drive a car that has damaged shocks? They’re as risky.
A damaged shock could cause your tire to slide off the road, making it challenging to navigate in an emergency. In high-speed traffic, the shocks are vital to ensure that your tires stay in the right place. They also prevent your vehicle from sliding when you need to stop or turn quickly.
You’ll notice that your car bounces more frequently than it usually does in the event of bumps in the road. It is due to the shock’s inability to control the suspension. The springs bounce back and forth since there’s nothing to slow them down. As a result, you can see your tires and wheels bouncing across the front of you as it occurs!
The most obvious indication that something isn’t right on your struts and shocks is when they leak fluid. It is a sign that there’s an issue with either part that needs to be repaired immediately before causing more injury elsewhere on your vehicle (like brakes).
Can Bad Sway Bar Links Cause Steering Wheel Vibration?
Sway bar links that are not in good condition will cause steering wheel vibrations. The sway bar is an essential component that makes up every vehicle’s suspension. They link the sway bar, which extends from side to side of your car, along with the other suspension components.
A broken sway bar link can cause a lot of noise when driving and cause irregular tire wear. They can also cause the steering wheel to vibrate at speeds on the highway. So it’s worth looking at what causes the steering wheel vibrations and how you can determine whether it’s due to bad links in the sway bar.
First, you need to know that problems with your wheels or tires can cause vibrations in your steering wheel. Many different causes must be assessed first to ensure that you make the correct repairs.
Ultimately, we conclude that it’s not the shock that triggers the vibration but how it is perceived. It can lessen the sound by altering how you perceive the impact.
It is crucial to realize that it is impossible to eradicate all vibrations. It is essential to acknowledge that it is an aspect of human nature.
