Nowadays, the car, considered a perfect servant, plays a vital role in our lives. We hope it operates smoothly and effectively along the roads when owning a car.
However, it’s unavoidable to face some problems during use because it’s a mechanical system. One of the most popular issues we usually face is vibration through floor of car.
We want to help you deal with that problem by providing basic info, reasons, and possible resolutions in this post. Now let’s start to solve them!
Vibration Through Floor Of Car: Description & Symptoms
Normally, cars may vibrate slightly while driving because of the execution of transmission gears and other engine parts.
But when these vibrations become more intense and harder, it’s time to check and diagnose the problems of your car to avoid undesirable damages later.
Here we’d like to list some of the most popular and visible symptoms you should pay attention to.
Continuous shake at high speeds
When you achieve certain high speeds, the feeling of harder vibration may come continuously, and vehicle vibration becomes tender when slowing down.
Vibration in the car when braking
The shaking movements happen whenever you push on the brakes. This circumstance usually comes with noisy sounds.
The shaking from the steering wheel
It is pretty observable that driving on rough surfaces makes your steering wheel shake. But if it starts to shake hard, even when on smooth roads, it’s a sign!
Intensely vibrate when accelerating
Whenever you speed up, the engine seems to vibrate excessively.
In this circumstance, the most moving area may be the floor because the problems may come from Constant Velocity (CV) joints or unbalanced parts below.
Why Is There Vibration Through Floor Of Car?
The most common culprit causing vibration through the floor of a car lies in its misaligned wheels. This situation occurs due to poor roads, weather changes, or even the faulty tires themselves.
Other reasons come from the brake, axle, engine, and the suspension system.
1. Tire’s Problems
Unbalanced tires
If vibration comes and goes while driving faster, it may come from unbalanced tires. Therefore, you need to check your tires to see any flat spots.
Based on the level of damage, you can decide to fix the issues by making tires balanced or changing the new ones if the damage is severe.
Underinflated tires
This is one of the tire issues that cause car vibration at certain speeds. Sometimes, we look at the tire’s appearance and suppose it’s still good, but actually not.
You should check the tire’s air pressure following the car manufacturer’s manual.
Tire wear & bald tires
If your tires become worn out, resulting in no tread and poor traction, the car’s performance is obviously affected.
Besides, the tires can wear unevenly, leading to cupping or wear on one side. As a result, you can feel tires vibrate when driving, even on smooth and good roads.
Tire defects
At low speeds (around 15 to 30 km/h), a deformed tire can cause your automobile to vibrate. In addition, there can be cap ply or inner liner defects.
These tire flaws can be caused during manufacturing, but extreme road hazards can also cause them.
The rims
The car’s rims could also be a tire-related issue. Striking big bumps or potholes can make the rims bent and damaged, leading to intermittent vibration while driving.
2. Wheel’s Problems
Damaged wheels
Sometimes, big potholes and other road failures destroy your wheels, resulting in severe vibration. To assess this accurately, you’ll need to utilize a wheel balance machine to inform you if the wheel can be repaired.
Moreover, you can come to an auto shop to get professional advice from a mechanic engineer to understand the circumstances better.
Wheel bearings
If a car feels like its vibrating via your steering wheel, your wheel bearings are likely old or broken.
Wheel bearings typically last the vehicle’s life, but if you usually go off-road, this broken one may be the reason behind the vibration.
Unbalanced wheels
Even if your tires are still good after hitting a deep and large pothole or a low curb, you risk damaging your wheels, leading to unbalanced or misaligned wheels.
Unfortunately, this circumstance is hard to diagnose on your own, so you should consult a trained repairer if you suspect this is the cause of vibration in trucks or cars.
3. Braking System Issues
Brake discs
Your car will shake if your brake rotor has problems with thickness. In other words, it’s called being out-of-round or excessive runout.
Then, when you apply pressure to the brake pedal, it vibrates. If the problem can’t be fixed soon, the disc becomes overheated as heavier wear and tear.
Brake drums
The brake drums can be out-of-round, leading to vibrations when you put on the brake. Besides, squeaking noises when pushing the brake pedal may be an outcome in this situation.
Caliper
Sometimes, the brake calipers may potentially become stuck in the brake disc.
Then, the car vibrates on highway when driving over 70 km/h, especially on the steering wheel, and you may smell the burning when you come to a halt.
4. Suspension System Issues
Out of alignment
Driving into potholes can potentially throw your suspension out of whack.
In this situation, the suspension problems can result in the car making shuddering noise. One of the realizable signs is that vibrations may occur at different rates.
Worn components
When it comes to a car making vibrating noise when driving or during braking, worn components could be the culprits. For example, ball joints, control arm bushings, etc.
In this scenario, the suspension system should be inspected and repaired. The most effective way is to replace worn components.
Loose components
The car vibrating at certain speeds but not every time might indicate loose components or bearings. If you strike a bump on the road, the rattle may increase and remain until you stop.
In this case, you should check whether those components are joined properly.
5. Axle Problems
Damaged axle
As you may know, bumping a pothole may cause many potential damages to your car that isn’t immediately obvious.
Damaged rear axles are one of the potential consequences. For example, if the axle is bent, the car will shake more intensely.
Broken drive shaft
In rear-wheel-drive cars, a drive shaft rotates when it distributes engine power to the back axles and wheels. If the driveshaft is deformed or bent, the rear-wheel vibration occurs.
You can not drive with a heavily damaged drive shaft, so it’s best to tow your rear-wheel-drive car to the mechanic.
Worn-out or broken constant velocity (CV) axle
CV joints are made of rubber and cover the ends of axles.
If these rubber components become torn, increasing dust and grime, this will be the answer to why my truck vibrates. If this happens, you should go to an auto shop and replace it.
6. Engine’s Problems
The air and fuel system
Sometimes, the vibrations can come from the air and fuel system. There are some minor points you should check, including:
- Fuel intake system: Sometimes, the intake can’t work properly because of clogs or bad injectors.
- Air and fuel filter: Suppose there are any clogs or damaged areas in the filter. It will decrease the oxygen for the ignition or affect the fuel flow. Later, your engine starts shaking because of a lack of air and fuel for the engine’s operation.
Loose hoses
Numerous hoses are functioning to convey fuel mixes, coolant substances, air flows, etc. If any of them are split, loose, broken, or detached, your engine can’t be provided with what it needs to operate.
As a result, the truck vibrating or stalling occurs. This flaw can be fixed by replacing damaged hoses and double-checking those hoses are well connected.
Conclusion
In conclusion, there are multiple possible causes of vibration through floor of car. You should check the wheel and tires first, then the brake, axle, engine, and the suspension system.
The reasons listed above are not fully complete, but they are most popular and understandable. And the best way to address the issues is to visit an auto shop.
After spending time on this, we hope you know where the problems come from and solve them properly!
