What Causes Severe Car Vibration?
2 Answers
If you notice slight vibration or deviation in the car body during driving, it is usually caused by tire-related issues. The specific explanations are as follows: 1. Poor Tire Balance: The primary cause may be poor tire balance. The owner should promptly perform a four-wheel alignment and dynamic balancing. If the vehicle doesn't pull to one side, just doing a tire dynamic balance should suffice. 2. Deformed Wheel Hub: This condition is more serious and may be caused by a deformed steel rim, requiring the owner to visit a professional repair shop for inspection. This situation 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 should be performed. Otherwise, uneven weight distribution can easily cause steering wheel vibration. Body vibration affects both driving comfort and handling judgment. 3. Deformed Drive Shaft: Another possible cause is imbalance due to a deformed drive shaft. This situation is more common in vehicles that have experienced chassis collisions.
As a seasoned driver with decades of experience, I've encountered my fair share of car vibrations, which usually stem from tires or the engine. Unbalanced wheels, deformed tires, or out-of-round conditions can make the entire body shake, especially noticeable at high speeds. Engine misfires are another common issue—aging spark plugs or faulty ignition coils can cause unstable operation. I remember one time my car was shaking badly, and after a thorough check, it turned out to be worn engine mounts; replacing them smoothed things right out. My advice: start by checking tire pressure and wheel balance—something you can do yourself. If the shaking persists, head to a professional shop to inspect the engine system without delay, as prolonged issues can compromise safety.
