The suspension system cause a car to shake when accelerating if something is wrong within the suspension assembly parts. There are many more instances that can cause the car to shake when you drive. In some cases, the car usually shakes even when it’s idle.
You could diagnose the car’s shaking as per the way the vibrations feel. For example, when the steering is the one that is shaking, you should direct your attention to the tie rod and bearings. Sometimes the wheels and tire assembly also cause the car to vibrate. Hence the reason why it’s very important to pay attention to any noise that’s made by your car.
How to know what is causing car vibrations.
- Vibrations from Engine Speed. These are vibrations that are felt as soon as the car engine starts. To some extent, there are vibrations during this occurrence that are considered abnormal. If you notice these abnormal vibrations they might be originating from a faulty timing belt.
- Shaking that occurs when accelerating. There are drivers who have noted that their cars started shaking when they reached a speed of 5o MPH and above. This is probably caused by a problem in the chassis or driveline.
- Vibrations originating from the engine rpm. The engine has many parts whose misfunctioning will cause a car to shake when accelerating. Some of the causes of an engine to shake include the following;
Reasons why the engine shakes.
- Spark plug. The spark plug is the part of the engine that is responsible for ignition. In fact, a faulty spark plug is one of the reasons why a won’t start. It usually creates a spark that ignites the fuel and air mixture within the combustion chamber hence starting the engine. When the spark plug is faulty you will notice that the engine will misfire. These misfires are the ones that cause the engine to shake.
- Motor mounts. The engine lies within the engine bay in a specific position. It is connected to the car body through motor mounts. The motor mounts are made of both plastic and metal in order to protect the car’s body. If they are faulty, the engine will not be held in place. Instead, it will be constantly shaking as soon as you turn it on.
- Disconnected hoses. The engine has a lot of fluids that serve different purposes. These are carried around the vehicle’s assembly to help different parts function as desired. Well if one of these hoses isn’t connected properly, it will cause the car engine to start shaking. So investigate the engine hoses when you notice that the car engine is shaking.
- Faulty timing belt. The timing belt is responsible for running the engine fan. At times it becomes worn out or loose so it doesn’t function appropriately. If the timing belt is faulty you will notice that the car engine shakes will be accompanied by a lot of noise. In fact, the vibrations and noise become worse as you accelerate to higher speeds.
- Faulty fuel intake. If something is wrong with the fuel intake, the car engine will not get sufficient power. Fuel intakes sometimes become clogged. This hinders sufficient fuel from being sent into the combustion chamber. The engine may misfire due to this and those misfires will cause the car engine to start shaking.
