1. Damaged Cooling Fan
All blades of a fan are made to keep balance while they are rotating at high paces. When one of them is missing or damaged, it would make the covering of a to shake.
Think of a damaged and swinging fan, when you turn it on, the whole covering would shake. In addition, the higher the pace, the more possible the problem would happen until it gets totally volatile. If you have experience in repairing a car, then you could solve this problem simply by changing the blades of the fan.
2. Separated Motor Mount
A car has a lot of motor mounts, which are used for 2 main functions: reducing the vibration or shock and fastening the motor to the engine. In other words, it is similar to a seat belt for your motor. A damaged or separated mount would not only make your automobile to shake, but it could also result in damage to different parts of your car. Other common signs that you could notice include the move of engine, loud noise and leak of oil. However, the good news is that you could easily replace a motor mount.
3. Issues with The Gas System
These days, a modern system of fuel could be as very complicated as a maze.In general, there are 5 major elements of a gas system that would make your car shake, including: gas pump, gas tank, gas filter, gas injector and carburettor (just in older car).
Issues with the gas system could range from an easy one like a gas filter, to more complicated problems that would need a mechanic.
4. Sparking Plug
Spark plug is the reason why a combustion would fire off in many situations. When you start a car, the spark plug generates a spark which burns an explosive combination to run the motor. When a spark plug is broken or not running appropriately, it would misfire and make your car begin to shake. A spark plug is often replaced for each 30 thousands miles and also needs to be examined regularly, but you could neglected easily for a long period.
5. Disconnected Hosepipe
The hosepipe of a car helps to transport important liquids and keep suitable vacuum pressure so that the engine would work smoothly. The problem happens when chemical substances such as lube or antifreeze damage the rubber tube in the car and leads to loss of pressure, disconnection and leak. Fortunately, examining and replacing a hosepipe is not so difficult and even simple in some situations such as making the fastener of a hosepipe tighter.
6. Issues with The Timing
In general, the timing of a car is really essential. When you turn it off for a short time, or one small part of the the timing is missing or broken, the whole motor could not keep the balance. To be sure, you should change a timing for each 100 thousands miles, but remember to examine it regularly.
7. Unbalanced or Bald Tire
It is a common sense that a car owner purchases the tire for the traction it offers. During the using process, the traction could be lost due to cupping or flat spot on the tires. When this issue happens to a tire, it would make the car easily affected by every small divot or fall that you could face on the road. In addition, this also has a negative effect on the balance of the tire. Basically, if a tire does not stay evenly on the street, then it is not going to move smoothly and make your car to shake when you increase the speed.
8. Shock and Strut
Shock and strut are the elements that help the tires and suspension of the car adapt to to the street. When those parts are not working, the whole car would face some problems such as small vibration of the unsteady suspension and the clattering sounds of the tires while they are rolling in a large holes.
9. Brake Pad
Brake pad is a thin block that presses onto the disc brake in order to stop the car. When a pad is broken and worn, then it could not be pressed onto the rotor and lead to the adequate amount of friction to stop your car. Thus, you should remember to check the brake pad regularly as it is quite easy to do, but changing it would be more complex if you have not done this before. In this situations, you should turn to a car expert.
10. Twisted Axles
Just as a red cart of kid, a car has a rear and front axles that are attached to the tire. When it is twisted, the wheel would get uneven. In these situations, you would notice the rhythmical shake when it moves down a street or hear a small sound coming from the front of your car.
Another method to know if your axle is twisted without using your probably dangerous vehicle is to place the motor into the gear and notice if there is any sputtering or clunking sounds from it, which mean a twisted axle and the demand for repair.
