What are the symptoms of a broken car stabilizer bar?

Symptoms of a broken car stabilizer bar: There will be noise when driving on rough roads, but no abnormal sounds will occur when driving on paved roads. If the stabilizer bar is broken, the car's body roll will increase when cornering. The car stabilizer bar connects the shock absorbers of the left and right wheels on the same axle, which helps reduce the body roll generated when the car corners. The function of the stabilizer bar is to prevent torsion of the bar body when the horizontal heights of the left and right wheels are different. The stabilizer bar generates anti-roll resistance to suppress body roll. When the suspensions on both sides move up and down synchronously, the stabilizer bar does not function. It only comes into play when the suspensions on both sides move asynchronously due to road undulations or steering during cornering.
A few days ago, I felt something strange when turning my car—the body swayed heavily like being on a boat, making it hard to control and prone to skidding, especially during high-speed cornering. On bumpy roads, I also heard squeaky noises, and the steering wheel felt loose and shaky. After sending it for inspection, I found out the stabilizer bar was broken. The mechanic said this kind of failure would worsen handling and, if ignored long-term, could damage the shock absorbers, cause uneven tire wear, or even lead to a rollover accident. Now I understand that as soon as similar symptoms appear, I should go to a professional shop for inspection and repair to ensure driving safety—never take it lightly.
