Problem overview

Some Mazda 3 owners report experiencing a clunking noise when braking at low speeds, particularly from the rear, which may indicate several underlying issues. Common causes include worn struts or shock absorbers, worn control arms, and worn ball joints, all of which can contribute to the noise. Additionally, loose bolts, misaligned brake pads, and worn sway bar links may also be culprits. Some owners find that worn brake pads fail to grip the rotor properly, resulting in noise during braking. Furthermore, worn-out struts can significantly affect vehicle stability and ride quality, leading to clunking sounds. If a loose CV joint is suspected, it is crucial for owners to seek a professional inspection to ensure accurate diagnosis and prompt resolution, as addressing these issues is vital for maintaining vehicle safety and performance.
