Why does the steering wheel shake when braking at around 60 km/h?
2 Answers
Here are the reasons why the steering wheel shakes when braking at around 60 km/h: 1. Tire deformation: Lift the front axle and rotate the wheels to check the static balance of the wheels and whether the tire or wheel hub is excessively deformed. If deformed, they should be replaced. 2. Tire dynamic imbalance: The car may experience steering wheel shaking within a certain speed range, requiring wheel dynamic balance to be redone. 3. Vehicle drivetrain malfunction: It is necessary to check whether the alignment angles of the front wheels meet the requirements, and adjustments should be made if they are off. 4. Part detachment: The ball joint of the half-shaft tie rod is worn and loose, or the rubber sleeve at the joint has fallen off, requiring replacement of the damaged parts.
I've been commuting by car for many years and have encountered this situation several times. When braking at around 60 km/h, the steering wheel shakes, which is quite alarming. The most common cause is wear and deformation of the front brake discs, leading to an uneven surface due to hard braking or high temperatures, resulting in uneven force when braking. Deformed wheel rims or unbalanced tires could also be the cause, becoming more noticeable at high speeds. I recommend going to a repair shop immediately to check the braking system, as you might need new brake discs. Ignoring this issue can easily lead to loss of control at high speeds, posing significant safety risks. Developing a habit of smooth braking, avoiding sudden stops, and regularly maintaining and inspecting brake components can greatly reduce risks. I remember after nearly having an accident once, I've insisted on getting a comprehensive check-up every year.
