Your car shaking when driving fast can be caused by several common issues:
- Wheel and tire imbalance : If the wheels are not properly balanced, it often causes vibrations noticeable at higher speeds, typically between 50-60 mph. This can also be caused by bent wheels or tires with uneven wear or tread problems. Tires that have been sitting unused and have gotten out of round may also cause shaking.
- Loose lug nuts : If the lug nuts on your wheels are loose, it can create dangerous shaking, especially at higher speeds.
- Worn suspension components : Ball joints, tie rods, bushings, and other suspension parts when worn or damaged can cause the wheels to move irregularly, leading to shaking.
- Axle and driveshaft issues : Problems with the driveshaft, CV axles, or U-joints may cause vibrations that increase with speed and can be felt on acceleration.
- Brake issues : Warped brake rotors or worn brake components can cause shaking, especially if the shaking occurs when braking.
- Engine issues : An engine misfire or other engine problems can also cause shaking, particularly during acceleration.
- Tire pressure and condition : Underinflated or overinflated tires, uneven tire wear, or damaged tires can result in vibrations while driving.
It is important to accurately describe when the shaking occurs (e.g., at what speed, during acceleration, braking, or cruising) to help pinpoint the cause. In many cases, tire balancing, alignment, and suspension inspection by a professional mechanic can resolve the problem. Because the shaking may be related to safety-critical components, it is advisable to have the vehicle inspected as soon as possible.
