Solving the Mystery: Identifying the Cause of a Knocking Noise from the Back Left Wheel
Knocking noise coming from the back left wheel is a common problem for many car owners. It is usually caused by a loose or worn suspension component, such as a control arm, sway bar link, or shock absorber. The knocking noise is usually heard when driving over bumps or potholes and can be very annoying. If left unchecked, it can eventually lead to more serious damage. To diagnose the issue, a mechanic will check the suspension components and inspect the wheel for wear or damage. If necessary, they may need to replace any worn or damaged parts in order to fix the problem and eliminate the knocking noise.
