Said It Here

Why does my car vibrate only when accelerating?

Front-end vibration during acceleration can happen at low speeds like 5 to 8 mph or at highway speeds, sometimes even shaking just the gas pedal or the entire cab. Drivers suspect worn components like transmission mounts, but the shaking makes it difficult to pinpoint the exact mechanical cause.
