Understanding Why Your Car Shakes During Acceleration

by

Experiencing your car shaking when you accelerate can be both unsettling and indicative of underlying mechanical issues. Identifying the root causes promptly is essential to maintain vehicle safety and performance.

Common Causes of Car Shaking During Acceleration

  1. Engine IssuesWorn-out spark plugs can lead to engine misfires, causing the car to vibrate during acceleration. Replacing faulty spark plugs can resolve this issue.
  2. Unbalanced TiresTires that are not properly balanced can cause vibrations, especially at certain speeds. Having your tires balanced by a professional can eliminate these vibrations.
  3. Damaged CV JointsThe CV (Constant Velocity) joints are crucial for transferring power to the wheels. A damaged CV joint can cause vibrations under acceleration and may require replacement.
  4. Bent Axle or DriveshaftAccidents or impacts can bend the axle or driveshaft, leading to noticeable shaking during acceleration. Professional inspection and repair are necessary in such cases.
  5. Worn Motor MountsMotor mounts secure the engine to the vehicle’s frame and absorb vibrations. When they wear out, increased vibrations can be felt, particularly during acceleration. Replacing worn motor mounts can alleviate this issue.
