Why Does the Steering Wheel Vibrate During Sudden Acceleration?

[LaDelilah]

There are several main reasons why the steering wheel vibrates during sudden acceleration: 1. Damaged spark plugs. Worn spark plug electrode gaps can lead to insufficient sparking, causing incomplete combustion of the air-fuel mixture and resulting in shaking during acceleration. Additionally, cracks in the ceramic part of the spark plug can prevent sparking, leading to a cylinder misfire, which may also cause shaking during acceleration. 2. Poor-quality gasoline can affect the atomization effect of the fuel injector, leading to incomplete combustion of the air-fuel mixture in the cylinder, which may also cause idle shaking. It is recommended to use higher-grade gasoline after finishing the current tank and perform a fuel system cleaning. 3. Uneven tread on the four-wheel tires, such as bulges or foreign objects, can be a fault. 4. Loose wheel bearings may also cause the car to shake while driving.

I used to drive my old car on the highway frequently, and the steering wheel would buzz and vibrate during sudden acceleration, which was quite frightening. Once, it was caused by unbalanced tires—when driving fast, the wheels wobbled, transmitting vibrations to the steering wheel. Later, after getting the tires balanced and adjusting the lead weights on the rims, the issue was resolved. If there's a problem with the drivetrain, such as a bent half-shaft or a twisted driveshaft, sudden throttle input can cause torque fluctuations, making the steering wheel shake. Worn engine mounts are also a common cause; if the mounts age and loosen, the engine lurches forward during hard acceleration, transmitting vibrations to the cabin. If these issues aren’t addressed promptly, high-speed driving can be dangerous. It’s best to visit a repair shop as soon as possible—safety first, don’t wait until something bad happens. Try noting the symptoms when the car shakes while driving and inform the technician for a more efficient diagnosis.

Buddy, my driving skills are average, but I often encounter steering wheel vibrations during sudden acceleration. Last month when I was driving back to my hometown, I tried overtaking and suddenly the steering wheel started shaking non-stop. I thought it was a road surface issue, but after inspection, it turned out the tire dynamic balance wasn't properly adjusted. Tire imbalance becomes particularly noticeable during high-speed acceleration, with vibrations transmitting through the suspension. Another possibility: if the drive shaft is worn or bent, uneven power transmission to the wheels can also cause shaking. There's also a potential issue with worn engine mounts - the engine becomes unstable during aggressive maneuvers. I suggest you visit a 4S shop for a quick check first. Don't push your luck driving like this, it's dangerous to wait until something happens on the highway. Pay more attention to wheel maintenance, and don't forget to do balancing after tire changes.

I've encountered this issue before. Severe steering wheel shaking during rapid acceleration is mostly due to failed tire dynamic balancing. When the car suddenly speeds up and the wheels rotate at high speed, unbalanced tires amplify the vibrations, causing the steering wheel to buzz. Another common factor is drivetrain failure, such as a deformed half-shaft or worn driveshaft bearings, which transmits torque impacts to the steering wheel. Loose engine mounts can also cause the same phenomenon. From my experience, the safest approach is to first go to a professional shop for inspection. They can test the tires using a dynamic balancing machine. Safety issues should never be taken lightly—don't delay, get it fixed as soon as you notice the problem.
