What Causes Vehicle Vibration During Driving?
4 Answers
If you notice slight vibration or deviation of the vehicle body during driving, it is usually caused by tire-related issues. Below are detailed explanations for the causes of vibration: 1. Poor tire balance condition, which requires immediate four-wheel alignment and dynamic balance inspection. If the vehicle does not deviate, a tire dynamic balance check will suffice. 2. Deformation of the steel rim, which requires the owner to visit a professional repair shop for inspection. This condition generally occurs in vehicles that have been in use for a long time. Typically, when replacing new tires or new steel rims, a tire balance check should be performed. Otherwise, uneven weight distribution can easily cause steering wheel vibration, affecting driving comfort and handling judgment. 3. Unbalanced deformation of the drive shaft, which is more common in vehicles that have experienced chassis collisions.
The car shaking while driving can be caused by various reasons. I've experienced it several times, common issues include tire problems: unbalanced wheels, improper dynamic balance; uneven tire wear, such as one side wearing out faster; or deformed rims causing unstable rotation. Especially when the speed reaches 60 to 80 kilometers per hour, the shaking becomes more severe. It's recommended to stop and check if the tire pressure is normal, and look for cracks or foreign objects stuck in the tires. Suspension system issues could also be the culprit, such as aging or leaking shock absorbers, or loose control arms, causing the car to sway while driving. Another possibility is an imbalance in the half-shaft or drive shaft, particularly noticeable when driving at high speeds. Every time I encounter this, I first go to the repair shop to check the tires and suspension, because safety comes first and minor issues shouldn't be ignored.
I've been repairing cars for years and enjoy hands-on problem-solving. Shaking usually stems from mechanical issues: for instance, worn suspension components like ball joints or bushings can cause wobbling; small stones stuck in tires or lost wheel balance can also lead to this. You can try pushing the wheel when the car is unloaded to see if it wobbles—unusual noises might indicate a bearing problem. It could also be an engine ignition system failure, such as aging spark plugs or damaged coils, with more noticeable shaking at idle. Another possibility is drivetrain issues like a misaligned half-shaft. When troubleshooting yourself, first use a jack to check wheel stability, and try swapping wheel positions to see if the shaking lessens. Don't overlook the brakes—warped brake discs can cause severe shaking when braking. Doing some simple tests before repairs can save a lot of money and hassle.
I'm concerned about driving safety, and vibrations should be taken seriously. Common causes include uneven tire pressure; unstable rotation due to damaged wheel bearings; or vibrations caused by loose engine mounts. It could also be spark plug issues leading to engine misfires and shaking. At high speeds, this is extremely dangerous and may lead to loss of control. It's recommended to slow down and pull over for inspection immediately upon noticing vibrations—don't take the risk of continuing to drive. Regular maintenance checks on tire wear and suspension can prevent problems before they occur.
