Driveline Issues: Problems with the driveline components (driveshaft, differential, axle) in a Cadillac can also result in shaking during acceleration. Worn or damaged components can cause vibrations that are transmitted through the vehicle. When the gas pedal is released, the power delivery to the wheels reduces, and the vibrations may diminish or disappear.
Engine Mounts: Engine mounts are designed to absorb vibrations from the engine and prevent them from being transmitted to the rest of the vehicle. Over time, these mounts can become worn or damaged, affecting their ability to dampen vibrations effectively. As a result, the engine may shake noticeably during acceleration, but the shaking could lessen when the gas pedal is lifted.
Transmission Problems: Issues within the transmission, such as worn or faulty components or low transmission fluid, can induce vibrations during acceleration. These vibrations can vary depending on the gear engaged and can be more prominent at specific speeds. Releasing the gas pedal may reduce the acceleration's intensity and cause the vibrations to subside.
Exhaust System Issues: Damage to the exhaust system components, such as a loose exhaust hanger, broken exhaust mount, or exhaust component resonance, can cause vibrations that are noticeable during acceleration. When the gas pedal is released, the engine load changes, which may alter the vibration's intensity.
It's crucial to have a qualified mechanic diagnose the cause of the shaking to ensure proper repairs and continued smooth operation of your Cadillac.
