Why is the car shaking violently?
2 Answers
The reasons for severe car shaking may include the following three: 1. Unbalanced wheels: Wheel imbalance is a common issue in many cars. Since it's impossible to ensure uniform quality during the manufacturing of tires and steel rims, wheels need to undergo dynamic balancing after assembly. Moreover, as tires wear out over time, periodic dynamic balancing is necessary after certain mileage. 2. Loose suspension components: The chassis suspension consists of various links and support arms, connected through ball joints and rubber bushings. Normally, these connections are tight, but as ball joints and bushings wear out, the components loosen, causing the suspension to become loose and resulting in body shaking while driving. 3. Excessive steering gear clearance: The car's steering system uses a rack-and-pinion mechanism to convert the steering wheel's rotation into wheel movement. Over time, wear between the gear and rack creates play, causing slight lateral wheel movement even without steering input, which leads to a sensation of body shaking.
I've experienced severe car shaking while driving, which is mostly due to issues with the tires or suspension system. For example, uneven tire pressure—when the pressure difference between the four tires is too large, it causes bouncing. Uneven tire wear or improper wheel balancing can make the steering wheel shake at high speeds. Then there are suspension components, such as aging shock absorbers or loose ball joints, which make the car wobble on bumpy roads. Once, while driving in the city, I noticed increased shaking when turning, and after inspection, it turned out to be rusted and leaking front suspension parts—replacing them fixed the issue. My advice is not to delay; if you notice a problem, pull over safely first. Visit a repair shop for a professional diagnosis. Regularly maintain your tires and suspension, checking pressure and wear at least every six months—prevention is better than repair.
