Shock absorber noise is caused by shock absorber oil leakage and aging of the shock absorber top mount thrust bearing. Below are the specific reasons for shock absorber noise: Shock absorber oil leakage: When the shock absorber leaks oil, the inside of the shock cylinder cannot be effectively lubricated, resulting in significant friction noise during operation. Aging of the shock absorber top mount thrust bearing: The thrust bearing is located in the engine compartment. Open the hood and press down on the body to listen if the noise is coming from the shock absorber top mount. If it is, it is most likely due to aging of the thrust bearing. If the shock absorber spring is deformed or broken, the only solution is to replace the entire shock absorber spring.

What to Do When Your Driver's License Has Been Deducted 12 Points?

When your driver's license has been deducted 12 points, you must report to the traffic management department of the public security authority at the license issuing location or the place where the violation occurred within 15 days to participate in a seven-day study session on road traffic safety laws, regulations, and related knowledge. Below is a detailed introduction regarding this study session: 1. Reason for participation: After completing the study session, the vehicle management office will conduct a subject one exam within 20 days. If you pass the exam, the points will be cleared, and your driver's license will be returned. However, if you fail the exam, you can only continue to participate in the study session and retake the exam. 2. Consequences of non-participation: If the driver fails to participate in the study session and exam within the specified period, the driver's license will be suspended by the traffic management department of the public security authority.

Can a car make a U-turn by crossing the yellow line?

Vehicles are not allowed to make a U-turn by crossing the yellow line. Crossing a single yellow line will result in a fine ranging from 20 to 200 yuan. Here are detailed explanations regarding crossing yellow lines: 1. Relevant regulations: According to Article 90 of the 'Road Traffic Safety Law of the People's Republic of China,' when a motor vehicle driver violates road traffic safety laws or regulations concerning road traffic rules, they shall be given a warning or fined between 20 and 200 yuan. 2. Others: Yellow solid and dashed lines are usually marked before and after bridges and on sections where U-turns are allowed, to separate opposing traffic flows. When serving as a no-crossing dividing line for opposing lanes, vehicles are prohibited from crossing or driving over the solid line side. The dashed line side permits vehicles to temporarily cross the line, turn, or make a U-turn. Vehicles crossing the line must yield to normally traveling vehicles.

Does driving with low fuel damage the car?

Driving with low fuel can be very harmful to the car. The related hazards are as follows: 1. Prone to shaking and stalling: When the fuel level reaches the warning line, even if there are no issues with the fuel itself, the vehicle may experience shaking, jerking, or stalling due to the fuel pump's inability to supply fuel promptly, caused by road bumps, turns, and other driving conditions. 2. Fuel pump overheating: Due to the design of certain vehicle models, the fuel pump relies on fuel for cooling. If the fuel level is at the minimum mark, the fuel pump may be 'exposed' above the fuel surface, leading to inadequate cooling, accelerated internal wear, overheating, short circuits, or even burning out. 3. Increased risk of clogged fuel lines due to debris at the bottom of the tank: With the fuel nearly depleted, the drop in fuel supply pressure and changes in flow rate can not only cause abnormal engine operation but also damage individual components, such as the fuel injectors, due to excessive heat and abnormal operation.

How to Determine if a Car Tire is Underinflated?

Two common methods are to observe whether there are flat spots on the front and rear tires or if the car tends to pull severely to one side while driving. The following is a detailed introduction to the effects of underinflated car tires: 1. Sidewall damage: Underinflated tires cause uneven force distribution, leading to long-term tilting that can result in sidewall wear. Sidewall wear can cause slow leaks, increasing the risk of a blowout. 2. Foreign objects puncturing the tire: Underinflated tires are more susceptible to damage from foreign objects, which is the most common type of tire damage. However, if not addressed promptly, it may worsen the damage to the tire. 3. Wheel rim flange deformation: When a car tire is properly inflated, the outer edge of the tire fits tightly against the wheel rim flange, preventing gas leakage. If the wheel rim flange is deformed due to impact, it will affect the tightness between the flange and the tire's outer edge, leading to slow leaks.

The working principle of the start-stop system is: When the vehicle stops due to congestion or at intersections, the driver steps on the brake pedal and shifts to neutral. The Start/Stop system automatically checks: The engine is idling and in neutral; The wheel speed sensors of the anti-lock system show zero; The electronic battery sensor indicates sufficient energy for the next start. When these three conditions are met, the engine automatically stops. 3. The engine auto start-stop automatically shuts off the engine during temporary stops (e.g., waiting at traffic lights) and restarts it when needed. The English name is STOP&START, abbreviated as STT. The STT intelligent fuel-saving system is a system that controls engine start and stop.
