When you drive and notice your car vibrating while moving, it could be a sign that there is a problem with the vehicle's safety and performance. Vibration not only causes discomfort but also affects the vehicle's stability and control, causes driver fatigue and can lead to serious damage if not corrected promptly.

Vibration when moving is a common phenomenon in many cars, especially cars that have been in use for a while.

According to statistics from the Vietnam Automobile Manufacturers Association (VAMA), up to 60% of cars over 5 years old encounter vibration problems when moving.

Although this phenomenon is not directly dangerous, it affects the driving experience and comfort of passengers, especially those prone to motion sickness.

Causes of Car Vibration When Moving

There are many causes of vibration in cars, including:

Tire

According to a Michelin survey, 35% of car vibrations are due to uneven tire wear. During use, the tire's contact points with the road surface will wear out at different rates, creating deeper concave areas. When the vehicle moves, these points will cause bouncing and shaking.

Solution: Technical experts can attach lead weights of different weights to worn locations to balance the tires.

Car Shakes When Moving
Vibration Will Be Generated Primarily By Deep Wear Points

Rim

Deformed and warped car rims due to collisions are a common cause of vibration. When the rim no longer has its original shape, the wheel will not rotate in the correct orbit, leading to kinematic imbalance.

Solution: Use a specialized ruler to check the rim runout. If the deviation exceeds 0.8mm (1/32 inch), the rim needs to be repaired or replaced.

Causes of Car Vibration When Driving
If the car rim is impacted and the car appears to vibrate, then the car rim is semi-axle.

Brake system

Vibration when braking is a sign that the brake drum and brake disc are warped, worn unevenly, or clogged with dirt. According to statistics, 20% of cars have problems with the brake system after 50.000km of use.

Solution: Remove, clean, grind flat or replace the brake drum and brake disc. However, flat grinding will reduce the life of these parts.

Dealing with Car Shaking While Moving
When you step on the brake pedal and vibration occurs, it means the brake drum and disc are bent or warped.

Power transmission system

Parts in the powertrain system such as the driveshaft, couplings... can become worn or damaged over time, causing vibrations and unpleasant noises. In particular, the driveshaft rotates at 3-4 times the speed of the wheel, so it can easily become loose.

Solution: Check and promptly replace worn or damaged parts in the power transmission system.

Causes of Car Vibration When Driving
If the driveshaft - driveshaft is worn or the cross joint is loose, the vehicle will vibrate and make unpleasant noises.

Engine

Even though it is constructed and assembled with high precision, car engines still create vibrations when operating. To minimize this, manufacturers often use rubber pillows (shocks) to isolate the engine from the chassis. However, shock absorbers will gradually lose elasticity over time, causing more vibration to be transmitted into the cabin.

In addition, vibration can also be caused by one or more cylinders not firing.

Solution:

  • Replace engine shock absorbers periodically
  • Check and handle weak or non-exploding cylinders (replace spark plugs, valves, clean injectors...)

Questions related to the topic of cars shaking while moving

1. Does vibration when moving cause immediate danger?

Although shaking when moving does not pose a direct danger, it affects the driving experience and comfort of passengers, especially those prone to motion sickness.

2. What is the percentage of vibrations caused by uneven tire wear?

According to a Michelin survey, 35% of car vibrations are due to uneven tire wear.

3. How to balance unevenly worn tires?

Technical experts can attach lead weights of different weights to worn locations to balance the tires. You can refer to additional reasons Dynamic balancing of car wheels to help you answer in the most detailed and accurate way.

4. What is the allowable deviation of the rim?

The parameter allows the deviation of the rim to be no more than 0.8mm (1/32 inch). If this level is exceeded, the rim needs to be repaired or replaced with a new one.

5. What is the percentage of cars that have problems with the brake system after 50.000km of use?

According to statistics, 20% of cars have problems with the brake system after 50.000km of use.

6. How to handle when brake drums and brake discs are warped or worn unevenly?

When the brake drum and brake disc are warped or worn unevenly, they need to be removed, cleaned, ground flat or replaced. However, flat grinding will reduce the life of these parts. Read some more The cause of the brake disc being bent/warped and the most effective solution. 

7. How many times faster does the driveshaft rotate than the wheel?

The driveshaft rotates at 3-4 times the speed of the wheel, so it can easily become loose, causing vibration and unpleasant noise.

8. Why do car engines still create vibrations even though they are constructed and assembled with high precision?

Even though it is constructed and assembled with high precision, car engines still create vibrations when operating. To minimize this, manufacturers often use rubber pillows (shocks) to isolate the engine from the chassis.

9. How long does it take for engine shock absorbers to be replaced?

Engine shock absorbers need to be replaced periodically because elasticity will gradually decrease over time, causing more vibration to be transmitted into the cabin. Read more ways to check and Replace car shock absorbers Safest, simplest.

10. What causes vibrations in the engine?

Vibration can also be caused by one or more cylinders not firing. Need to check and handle weak or non-exploding cylinders (replace spark plugs, valves, clean injectors...).

11. Why is it easier for modern suspension systems to transmit vibrations into the cabin?

Modern suspension systems help drivers feel the road surface well, but at the same time it also makes vibrations transmitted into the car more easily.

12. At what speed is the vibration felt most clearly?

When the car runs at a speed of 50km/h, the driver begins to feel dynamic imbalance. However, at a speed of 80km/h, the vibration feeling will be most obvious.

13. If you feel vibrations from the steering wheel, what part should you check?

If you feel vibrations from the front of the steering wheel, you need to check and balance the tires first.

14. If you feel vibrations from the back seat, what part should you check?

If you feel vibrations from the rear seat, you need to check and balance the rear tires.
