Car wobbling can be attributed to several factors from the perspective of wheel balance: Wheel imbalance is a common issue in many vehicles. During manufacturing, tires and rims cannot guarantee perfectly uniform quality, and worn tires may lead to rotational imbalance, subsequently causing body sway. From the perspective of steering gear clearance: Over time, the meshing gears and racks wear out, creating play between them, which results in a sensation of body wobbling. From the suspension framework perspective: Suspension components are connected via ball joints and rubber bushings. However, as these ball joints and bushings wear out, the components may loosen, leading to a loose suspension system that causes body wobbling during driving.

I once experienced body swaying when driving at high speeds and was quite puzzled at the time. Later, I realized it was mainly due to tire issues, such as inconsistent tire pressure or uneven tire wear, especially with the front tires having the greatest impact. Another important factor is improper wheel balancing—when the balancing weights on the rims fall off, the car body tends to sway back and forth. Additionally, aging suspension systems can easily cause swaying; for example, cracked bushings on the lower control arms or failed shock absorbers can make the car feel like riding a boat. There was also a time when the car noticeably wobbled during braking, and it turned out to be warped brake rotors. So, I recommend starting with tire inspections, and regularly performing wheel alignment and balancing is essential.

Last time my old car was swaying left and right on the road, which made me quite nervous. The mechanic said this kind of wobbling usually focuses on several aspects: first is tire-related issues, where inconsistent tire pressure or abnormal tire wear can cause steering wheel vibration; second is suspension components, such as loose ball joints or damaged lower control arm bushings; third is braking system problems, especially when shaking during hard braking, which is basically a sign of warped brake rotors. Additionally, some cars experience this due to excessive wheel bearing clearance, which can be felt by shaking the tire by hand. The mechanic said such problems need to be checked item by item, and it's important to pay attention to tire condition and perform regular maintenance.

My car experienced noticeable shaking when driving on the highway, and the repair shop later helped me identify the cause. The main issue was a problem with tire dynamic balance, where the balancing weights had fallen off, causing uneven wheel rotation. Additionally, the inspection revealed that the shock absorbers had failed completely, losing their damping function. Slight deformation of the wheel hub can also cause irregular wobbling, which is usually caused by driving too fast over potholes. In short, it was a combination of wheel imbalance and suspension damping failure. It is recommended to check tire pressure monthly and slow down when driving over rough roads to reduce such failures.
