Is Parking on a Slope Harmful to the Car?

Parking on a slope definitely causes some harm to the car. When parked on a slope, the car is subjected to the component of its own weight along the slope, and this force is mainly borne by the handbrake. The handbrake cable, being in a taut state for a long time, will gradually stretch, and the suspension will bear pressure. This reduces the reliability of the handbrake, making issues like the car not staying parked and rolling backward increasingly apparent. Impact on the suspension: When parking on a slope, the side facing downhill bears greater pressure on the suspension. Over time, this causes uneven aging and varying stiffness between the front and rear suspensions, affecting ride comfort. Damage to the handbrake braking system: Parking the car on a slope means the handbrake has to bear the pressure. The handbrake fixes the vehicle by pulling the brake via a cable. When parked on a slope, the handbrake cable continuously bears the component of the car's weight parallel to the slope. Prolonged exposure to this stress can fatigue the handbrake cable, affecting its performance. Risk of rolling: If parked on a slope for an extended period, the handbrake may age and fail at any time, leading to the possibility of the car rolling away.

Is a Car with Cut Rear Fender Considered an Accident Vehicle?

A car with a cut and replaced rear fender is considered a major accident vehicle. If the rear fender has undergone cutting and replacement, it falls under the category of an accident vehicle. However, if it only underwent panel beating repairs without any cutting or welding, it is not classified as an accident vehicle. Introduction to Accident Vehicles: An accident vehicle refers to a car that has suffered damage due to non-natural wear and tear, leading to a decline in mechanical performance and economic value. Generally, these are vehicles with structural damage, where the performance is inferior to its original state. An accident inherently indicates issues with the car, and driving such a vehicle may pose safety hazards. Accident Vehicle Inspection: Methods include exterior inspection, light inspection, insurance record check, and interior examination. When purchasing a used car, it is essential to carefully observe aspects such as the manufacturing date, actual mileage, whether the car has been involved in any major accidents, and the level of daily maintenance provided by the previous owner.

How to Apply for a Ride-hailing Vehicle Operating License?

There are generally two channels to apply for a ride-hailing vehicle operating license: one is to go to the local vehicle management office or traffic police department, and the other is to apply online. To apply at the local vehicle management office or traffic police department, you need to prepare the required materials in advance and then proceed with the staff. The materials to be prepared include: 1. For vehicles owned by a legal entity: business license, identity proof of the handling person and its copy should be provided. 2. For ride-hailing vehicles: application form for the transport certificate. 3. Original vehicle license and its copy: for newly purchased vehicles, the purchase invoice and original vehicle registration certificate and its copy should be provided. 4. Comprehensive performance test report of the vehicle: qualified report. 5. Ride-hailing platform company: letter of intent for service agreement.

What are the conditions for returning or exchanging a car?

According to the Automobile Three Guarantees Law, the conditions for returning or exchanging a car are as follows: 1. The vehicle has undergone two repairs for serious safety performance failures: If the serious safety performance failure has not been resolved or a new serious safety performance failure occurs. 2. After the engine or transmission has been replaced twice: Or if the same major component of the engine or transmission has been replaced twice due to quality issues and still cannot function properly. The replacement counts for the engine, transmission, and their major components are not duplicated. 3. Steering system, braking system: Or if the same major component of the suspension system, front/rear axle, or body has been replaced twice due to quality issues and still cannot function properly.

How Often Should the Final Drive Oil Be Changed?

The final drive oil can be changed every 80,000 to 100,000 kilometers. For specific models, please refer to the maintenance manual. Here is an introduction to the final drive oil: 1. Introduction to Final Drive Oil: The final drive is actually the part connecting the two rear wheels of a car. The correct technical term for the final drive is the final reduction ratio gear. Final drive oil is the oil injected into those gears. Final drive oil is just a customary term; in layman's terms, it is actually gear oil, also known as differential oil. 2. Functions of Final Drive Oil: Final drive oil is used in various gear transmission devices to prevent tooth surface wear, scratches, sintering, etc., thereby extending their service life and improving power transmission efficiency. Gear oil should have good anti-wear and load-bearing properties, as well as appropriate viscosity. Final drive oil should also have good thermal oxidation stability, anti-foaming properties, water separation performance, and rust prevention properties. Since gear loads are generally above 490 MPa, and the load on hypoid gear surfaces can reach as high as 2,942 MPa, extreme pressure anti-wear agents are often added to gear oil to prevent oil film rupture, which can cause tooth surface wear and scratches. Sulfur-phosphorus or sulfur-phosphorus-nitrogen additives are commonly used. The working temperature of gear oil is generally lower than that of internal combustion engine oil and largely varies with environmental temperature changes. The oil temperature of vehicle gear oil generally does not exceed 100 degrees Celsius.

Why is it not recommended to repair dented side skirts?

Here are the reasons why repairing dented side skirts is not recommended: 1. Side skirts are inherently prone to friction: Many repair shops fail to apply the adhesive particle layer after sheet metal work, making side skirts vulnerable to damage. If the repair is not professionally done, the surface may become uneven over time and eventually develop cracks. Additionally, the original anti-rust layer inside the side skirt may be damaged during sheet metal work, leading to rusting from the inside out in the future. However, this can be mitigated by spraying anti-rust wax into small holes yourself. 2. For plastic materials: Generally, pouring hot water to try to make the dent pop out is sufficient, as plastic has some elasticity. If that doesn't work, specialized suction tools can be used for pulling, followed by touch-up paint.
