1. Worn-out Struts or Shock Absorbers: Struts and shock absorbers play a crucial role in controlling the movement of the wheels and the suspension system. Over time, these components can become worn out or damaged, leading to a thumping noise when the vehicle turns.
2. Faulty Control Arms: Control arms are responsible for connecting the wheels to the vehicle's frame and allowing them to move smoothly. Damaged or loose control arms can result in thumping noises during turning maneuvers.
3. Tie Rod Ends: Tie rod ends are essential components of the steering system that connect the steering rack to the wheels. If they become damaged or worn out, they can cause knocking or thumping sounds when turning the vehicle.
4. Loose Ball Joints: Ball joints allow for smooth movement between the suspension components. If they develop excessive wear or become loose, they can produce thumping noises while turning.
5. Drive Shaft Issues: In some cases, a faulty drive shaft can also be the culprit behind thumping noises when turning. This can be particularly noticeable when the steering wheel is turned to one side and the vehicle is put under load, such as when accelerating.
6. Wheel Bearing Problems: Wheel bearings allow the wheels to spin smoothly. Worn-out or damaged wheel bearings can create a thumping noise that becomes more noticeable when turning.
It's important to identify the exact source of the thumping noise to ensure proper repairs. If you're experiencing this issue in your Honda Civic, it's recommended to take it to a trusted mechanic for a diagnosis and appropriate repairs.
