Why Does the Car Steering Wheel Make Noise?

Car steering wheel noise can be caused by: 1. Lack of lubrication in the steering column, resulting in high friction; 2. Insufficient power steering fluid; 3. Issues with the universal joint; 4. Aging and hardening of the rubber bushings in the suspension stabilizer bar links; 5. Damage to the thrust bearing. The function of the steering wheel is to convert the force applied by the driver on the steering wheel edge into torque, which is then transmitted to the steering shaft to control the vehicle. The working principle of the steering wheel is: the steering mechanism converts circular motion into linear motion through a rack and pinion system, pushing the wheels to rotate via the steering linkage, thereby achieving the car's steering function. Steering wheels are categorized into: single-spoke, dual-spoke, triple-spoke, and four-spoke designs.

What does a bulb with an exclamation mark mean on a car?

Yellow bulb with an exclamation mark: This is the lighting fault indicator, indicating that there is a fault with one of the car lights. Solution: Visit a 4S shop for inspection and repair as soon as possible. Alternatively, you can check it yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue. The exclamation mark is a common fault indicator in cars. Besides the yellow bulb with an exclamation mark, there are four other forms of exclamation mark indicators: an exclamation mark inside a triangle, an exclamation mark inside a yellow gear, an exclamation mark inside a circled parenthesis, and an exclamation mark inside a parenthesis with a horizontal line below. Here’s a detailed analysis: General Fault: An exclamation mark inside a triangle. If this symbol lights up, it indicates a fault with the car's general performance, components, or functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor failure. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: An exclamation mark inside a yellow gear. This is the automatic transmission fault warning light, indicating a fault with the transmission or that the transmission lubricant is below the normal range. Transmission oil should be replaced promptly. Brake System Fault: An exclamation mark inside a circled parenthesis. This represents a brake system warning, indicating either a brake system malfunction or low brake fluid level. Immediate inspection and repair of the brake system are required to avoid accidents. Tire Pressure Anomaly: An exclamation mark inside a parenthesis with a horizontal line below. This represents the tire pressure monitoring warning light, which illuminates when the car's tire pressure is too low. Check the tire pressure and restore it to the normal range.

Slippage or damage to the air conditioning clutch; 4. Air intake system leakage; 5. Insufficient engine power output. Solutions for high RPM include: 1. Adjusting the throttle opening; 2. Replacing the fuel injector, air conditioning clutch, air intake system, or engine. The reasons for unstable RPM gauge readings are: 1. Oil accumulation and carbon buildup in the throttle; 2. Dirty intake tract; 3. Blockage in the fuel system, particularly the fuel injector; 4. Faulty intake pipe.
