Does a Broken Half Shaft Affect the Car?

If the half shaft is damaged, the car may experience minor issues like abnormal noises and bumps when running, or severe problems such as inability to move, causing the car to deviate from its path or shake violently. Below are the relevant details: 1. Damage to the half shaft: Initially, it is usually caused by the rupture of the rubber dust cover on the inner or outer CV joint, allowing road dust and debris particles to enter the CV joint lubrication surface. At the same time, the lubricating oil inside the CV joint is completely thrown out, leading to dry friction damage on the inner and outer CV joint ball surfaces. Generally, if you hear a rattling sound from the left front wheel when turning the steering wheel fully to the left, it indicates damage to the left outer CV joint. Conversely, it indicates damage to the right outer CV joint. 2. Side-to-side swaying: When the car is driving straight at a speed of 70-80 km/h, if you notice a side-to-side swaying or shaking sensation in the front part of the car, especially accompanied by a metallic impact sound during sudden acceleration, but the steering wheel feels normal, and there are no abnormalities when releasing the throttle or coasting, this indicates damage to the inner CV joint of the half shaft. In this case, the entire half shaft assembly needs to be replaced.

What are daytime running lights?

Daytime running lights are installed at the front sides of a vehicle to signal its presence during the day, making the vehicle more noticeable to others. Here are some additional details about daytime running lights: 1. Daytime running lights are not for illumination but serve as signal lights. 2. While adding daytime running lights can make a car look cooler and more stylish, their primary purpose is not aesthetics but to enhance the vehicle's visibility. Additional information: 1. When overtaking, a motor vehicle should activate the left turn signal in advance, switch between high and low beams, or sound the horn. 2. During nighttime encounters with oncoming vehicles, drivers should switch to low beams when the distance to the opposite vehicle is more than 150 meters. 3. When encountering non-motor vehicles on narrow roads or bridges, drivers should use low beams. 4. When turning left, drivers should turn from the left side of the intersection center point, activate the turn signal during the turn, and use low beams when driving at night. 5. When driving at night without streetlights, under poor lighting conditions, or in low-visibility situations such as fog, rain, snow, dust, or hail, motor vehicles should turn on the headlights, position lights, and taillights.

What is the normal RPM for an automatic transmission car?

Automatic transmission cars typically operate at a normal RPM range of 1800 to 2000 rpm. The engine RPM is directly related to the number of work cycles per unit time or the effective power output of the engine. In other words, the engine's effective power varies with different RPM levels. Therefore, when specifying the effective power of an engine, the corresponding RPM must also be indicated. An automatic transmission generally refers to a car's automatic gear-shifting mechanism. While driving, the control system of the automatic transmission automatically selects the appropriate gear based on the engine's RPM and load, replacing the driver's subjective judgment of timing and gear-shifting operations. Most automatic transmission cars have six gear positions, arranged from top to bottom as: P, R, N, D, S, L.

What are the reasons for the failure of the power-folding function of the rearview mirror?

Common reasons for the failure of the power-folding function of the exterior rearview mirror are as follows: 1. The battery is disconnected or dead: The exterior rearview mirror must be reset to function properly. The specific reset method is to manually operate the folding button. 2. Manual folding: The next time the vehicle is unlocked, the exterior rearview mirror will not automatically unfold. You need to enter the vehicle and press the button on the door to manually unfold the exterior rearview mirror. 3. Other reasons: Focus should be placed on checking mechanical and electronic control issues. Additional information: The purpose of the power-folding rearview mirror is that, as the widest component installed on the vehicle, it is most susceptible to impact in the event of a collision. To minimize scratches, the rearview mirror needs to have a folding function.

How to Use Front and Rear Fog Lights Correctly?

Fog lights are generally used as emergency lighting tools under severe weather conditions and should not be used as daily lighting. Basic introduction to fog lights: 1. Usage scenarios: Article 81 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" clearly states that when visibility is less than 200 meters in rainy or foggy weather, motor vehicles should turn on fog lights. 2. Precautions for use: Fog lights can become very dazzling in good visibility conditions. The glaring light from fog lights can interfere with or even harm the eyes of other drivers, potentially leading to accidents. Therefore, traffic regulations in many countries explicitly prohibit the use of fog lights when visibility is good.
