What is the reason for jerky steering?
2 Answers
The reason for jerky steering may be an issue with the ball joint. Here is an introduction to the ball joint: 1. Introduction: Automotive ball joints are divided into inner ball joints and outer ball joints. 2. Function: The inner ball joint connects to the transmission differential, while the outer ball joint connects to the wheel. Whether it's power output or vehicle turning, the outer ball joint plays a role. 3. Components: A ball joint generally consists of a bell-shaped housing, a tripod bearing or steel balls, a dust cover, a retaining ring, and lubricating grease. 4. Symptoms of damage: If the front wheel ball joint is damaged, the following symptoms may appear: rattling noise on bumpy roads; unstable vehicle, swaying left and right; and steering failure during braking.
I've driven quite a few cars and encountered jerky steering issues several times. The main causes usually stem from problems in the steering system. The most common issue lies in the power steering components: For older vehicles with hydraulic power steering, the aging power steering pump may cause insufficient oil pressure, making the steering feel heavy and jerky when turning the wheel; in newer cars with electric power steering, it could be due to motor or sensor malfunctions, resulting in uneven power assistance. Another factor is wear or lack of lubrication in the universal joint on the steering column, which makes turning less smooth, especially during sharp turns. Tire issues shouldn't be overlooked either, such as uneven tire pressure or misaligned wheels, which can amplify the jerky sensation. I recommend first checking the power steering fluid level or the electronic system's condition, topping up or cleaning the lubrication points; if the problem persists, it's best to take it to a repair shop for a comprehensive inspection to avoid damaging other components and compromising driving safety.
