What are the symptoms of a damaged car steering knuckle?

[McCaden]

The symptoms of a damaged car steering knuckle include: 1. Steering gear oil leakage, mainly from the upper cover, the small shaft connected to the universal joint, and the dust covers at both ends of the steering gear; 2. Excessive free play in the steering wheel and unusual noises; 3. Heavy steering when turning the wheel. The steering knuckle is a critical safety component in the car's steering system, affecting the vehicle's driving stability, safety, and steering responsiveness, requiring high strength and fatigue resistance. The functions of the steering knuckle are to transmit and bear the load of the car's suspension system, support and drive the hub to rotate around the kingpin for steering. Causes of steering knuckle damage include: 1. Poor driving habits of the driver; 2. Excessive force when turning.

I felt unnatural and intense shaking in the steering wheel while driving, especially during turns or acceleration—so severe it made my hands go numb. Sometimes, I could hear creaking or metallic grinding noises near the wheels, as if parts were being squeezed. The car also kept pulling to one side, forcing me to grip the steering wheel tightly just to maintain a straight line. It almost got out of control on the highway. After inspection, I learned the steering knuckle was the issue. Apparently, once it cracks or deforms, the stability connecting the wheels is lost, leading to poor handling. Tire wear becomes uneven, with one side wearing out faster, shortening their lifespan. I recommend getting it diagnosed at a repair shop ASAP and avoiding potholes to prevent further damage. After fixing it, the car runs much smoother.

I have some knowledge about car structures, and the symptoms of a damaged steering knuckle are quite obvious. When driving, the steering wheel vibrates violently, and you can feel it even on smooth roads, as if the wheels are bouncing. There's a clicking sound when turning, possibly due to loose or deformed internal connection points. This affects the overall balance of the vehicle, weakens the shock absorption, and makes the car wobble more over bumps. The cause is usually from hitting potholes or the impact of an accident. If the tire tread shows uneven wear, it's an early sign. For prevention, I avoid potholes when driving and have the suspension system checked regularly during maintenance. Repair requires replacing the part, otherwise, handling becomes dangerous, especially at high speeds where loss of control is more likely.

I don't drive much, but once my car had an issue where the steering wheel kept shaking, and there was a strange noise when turning, like something was rubbing. The car also kept pulling to one side, even when driving straight. Later, it was diagnosed as a broken steering knuckle. This part connects to the wheels, and once it's cracked or loose, the whole handling becomes unstable. Symptoms include these unusual noises and vibrations, and over time, the tires can also wear out. It's best to fix it early—safety first—don't wait until something serious happens.
