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.

Causes of Knocking Noise in Back Left Wheel of Automobile



There are several potential causes of a knocking noise coming from the back left wheel of an automobile. The most common causes include mechanical wear and tear, poor wheel alignment, damaged ball joints, and worn suspension parts. Mechanical wear and tear can occur over time due to normal use and can lead to a knocking noise. Poor wheel alignment can also cause the wheels to be out of balance, causing a knocking noise when the car is driven. Damaged ball joints can also cause a knocking noise due to the lack of support to the wheel.
