Shaking in a rocking chair can be very relaxing but having the same experience when you are driving a car or even is alarming. A vibrating vehicle is not good news. However, the truth is even your newly purchased auto can show these signs. There are many causes of this disturbing incident, but don’t worry, in this article, we are about to show you the best ways to diagnose the roots of car engine vibration and the detailed guide on how to completely eradicate this problem. Now, let’s begin!

6 Main Reasons Of Engine Vibration
Experiencing vibration while driving is not only annoying but it can cause serious accidents too. If you detect any such problem, you should diagnose for finding out the cause and take it to a repair shop. Here are the six most commonly occurred reasons for the vibration of an engine:
It is a common but dangerous problem because misaligned wheels can cause dangerous driving conditions. So, if your car shakes or vibrates, check the wheels or take it to an automobile shop for a diagnosis.
Wheel bearings can be the culprits too. Although they are likely to last for the lifetime of the car, you need to replace them in case if the vehicle is extensively used.
Problems In Tires
Similarly, misaligned tires can also cause the shaking problem. Check them for alignment issues. If one of them is imbalanced, it can affect the others and prevent the car from driving straight. Separated treads from the tires can also cause the same problem.

The brake caliper or rotors are to blame if the vibration intensifies while using the brakes. Caliper sticking is easy to identify because you will get a burning smell when stop driving. On the other hand, warped rotors prevent the brakes from working in full pressure, causing the vibrations. You should take your vehicle to an expert mechanic if the problem is with the brakes.
Issues With The Engine
Loose engine mount will allow the motor to move around under the hood and cause a significant amount of shaking in the process. Most of the cars have four mounts, and some have more than that. However, you’ll feel the vibration while driving if just one of them is loose.
Worn Ends Of Tie Rods
These are the parts that establish a connection between the wheels and the steering. They help to keep the wheels in the same direction. When their ends start to wear out, they struggle to keep the wheels in line, causing shaking and vibration.
Low Transmission Fluid
It’s one of the most familiar causes of engine vibration. If the level of transmission fluid runs low, your car will shake upon acceleration. It needs immediate attention because the shake it creates is quite intense.
There are more causes of engine vibration. The problem can arise for a bent axle, spark plugs, worn ball joints, loose hoses, and many other reasons. You should be careful and take the car to a service center if it shows any vibration while driving.

Low level transmission fluid, tires issues, or brakes error can all cause car engine vibration. But here we will talk about cylinder, which is usually the main reason causing vibration to your engine. Here are the steps you should follow:
Step 1: Spot The Problem Source
In order to fix any problem, you need to find its source, and it is the same with cylinder misfire. The easiest way for drivers is to check the diagnostic trouble codes. The checking can help you determine whether your cylinders have one, multiple or no misfire at all. OBD-II scanner is an useful tool for this task which can be sold at any car parts stores. Easy as it sounds, yet this first step will save you a lot of time and efforts, rather than chasing dead-end solution.
It is the best if you find your cylinders having no problem at all. However, if they really did have misfires, the reasons usually come from one of four systems: control sensors, fuel supply, air supply or the computer. Drivers can check the amount of air, fuel, or the failure in ignition.
Step 2: Analyze The Problem
Understanding the problem from the beginning can be really helpful in this step, since different problems have different way to solve: If you get single-cylinder misfires, it is often caused by a failure in the engine. However, random multiple misfires from the cylinder can usually be caused by the outside sources, rather than by the engine itself. Last but not least, mechanical failure and unbalanced rotating assembly causes no misfire code.
The culprits for this problem are usually fuel injector problems or failures in ignition. The tip for drivers here is to check spark plugs, ignition coil and plug wires. If the cylinder’s coil is broken, it is quite easy to determine and repair. However, many engines use one coil to power two cylinders, so if that single coil has any problem, both cylinders are mostly die as well.
Also, if you get a lean condition notification diagnostic code, you most likely to have a failure fuel injector.
Random Multiple Misfires
Many drivers are not knowing this, but problems which affect the engine entirely like this one are usually resulted by the “engine support” systems like: air intake, fuel supply or electronics systems. A dirty airflow sensor, sensor failure and vacuum leaking air can be potential culprits. Of course, air restrictions in the intake can cause vibrations for your automobile, as well.
Problems with camshaft, damaged head gasket, broken piston ring,… are mechanic problems, and they often make your car shaky through cylinder misfires. If you get no misfire at all, there is high chance that you have an unbalanced rotating assembly, causing engine shaking. Many engines use balance shafts or harmonic balancer to reduce car engine vibration, so if you have one, check it out, since it might be your source of shaking problem.
Step 3: Replace Damaged Car Parts
Understood the condition of your beloved car, it is time to remove the damaged parts. New drivers are recommended to go for a car repair shop, but if you want to take care the automobile by yourself, here is the tool list that you might need:
- Ratchet Wrench
- Engine Pulling A-Frame
We will now cover up the most common problem with car engine vibration: Vacuum leak, which makes idling slower and damage the engine along with gas mileage.
The sign of awareness for this case is the cracks and holes on the vacuum hoses. Open the trunk to locate the vacuum system, and we will find the vacuum hoses right in the middle. Remember to check the hoses carefully to make sure it is the real problem. Then remove the damaged vacuum hose and set aside for a while.
After the examination, vacuum lines are the next target to remove. The lines is inside vacuum hose which was taken earlier. In cold temperatures, the vacuum lines can be damaged and shattered, which could create leaks or be broken. The only solution for that is to install the new ones right after this.
Also remember to wear gloves and eye wear to protect yourself.
