The reason for abnormal noise in electric vehicle shock absorbers is insufficient lubrication in the shock absorber cylinder. When this occurs, applying some grease to the shock absorber cylinder can eliminate the noise. Relevant information is as follows: 1. Introduction: An electric vehicle is a relatively common means of transportation. The main components of an electric vehicle include the frame, motor, battery, and controller. The controller is used to manage the entire vehicle's electrical system. Without the controller, the electric vehicle cannot operate normally. 2. Controller: The controller is usually fixed under the rear seat. The motor is the power source of the electric vehicle, responsible for driving the vehicle forward. The battery is a component used to store electrical energy, supplying power to all electronic devices in the vehicle.

When I drive, the shock absorbers often make squeaking noises, especially when going over potholes or speed bumps, which feels quite annoying. This could be due to the shock absorbers aging, with the oil seals wearing out and causing leaks, or the rubber bushings on the suspension becoming loose. Electric vehicles are heavier, putting more strain on the suspension, making such noises more likely to occur. If left unrepaired, it will only get worse, affecting the car's stability and potentially causing dangerous skidding during sharp turns. I recommend avoiding bumpy roads when driving and regularly checking if the tire pressure is normal, but it's best to visit a professional repair shop as soon as possible for a thorough inspection. You can also do a preliminary check under the car for oil stains or foreign objects, but avoid forcing anything to prevent further damage. Safety comes first—small issues left unattended can lead to repair costs more than doubling over time.

Vehicle Inspection in 2020, Is Inspection Required Again in 2021?

If the vehicle was inspected in 2020, another inspection is required before the expiration of the 2021 inspection validity period. The new inspection regulations, implemented from November 20, 2020, allow vehicles inspected within ten years to receive a 2-year valid motor vehicle inspection certificate. Below are some inspection considerations: 1. Check for any traffic violations and handle them promptly. 2. Ensure the trunk has a fire extinguisher and warning triangle. 3. Replace license plates if they are damaged, worn, or faded. 4. Remove any added accessories like running boards or strobe lights, and revert modified rims to original. 5. For vehicles with seven or more seats like minivans, ensure all seats are in place as per the registration, with seat belts for each.

What type of engine oil should be used for the Changan CS55plus?

Changan CS55plus can use Shell HX7 5w-40 synthetic engine oil. Introduction to engine oil: Engine oil, also known as engine lubricant, has a density of approximately 0.91kg×10³. It serves multiple functions for the engine including lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. It is often referred to as the 'blood' of automobiles. Under such demanding operating conditions, only qualified lubricating oil can reduce wear on engine components and extend their service life. Composition of engine oil: Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of lubricating oil, determining its fundamental properties. Additives are used to compensate for and improve any deficiencies in the base oil's performance, as well as to impart certain new characteristics, making them an essential part of lubricating oil.

What is EPSF oil?

EPSF is power steering fluid. Power steering fluid is a special liquid used in a car's power steering pump. Through hydraulic action, it can make the steering wheel very light, similar to automatic transmission fluid, brake fluid, and shock absorber fluid. Introduction to Power Steering: EPS stands for Electric-Power-Steering, which is an electric power steering system. The electric power steering system is the development direction of automotive steering systems. This system directly provides steering assistance through an electric power motor, eliminating the need for a power steering pump, hoses, hydraulic oil, drive belts, and pulleys mounted on the engine, saving energy and protecting the environment. Function of Power Steering Fluid: Power steering fluid can also be referred to as 'power steering oil' or 'steering gear oil,' used to transmit hydraulic pressure in the steering system. Power steering fluid has high viscosity, poor fluidity, a distinct odor, and is somewhat corrosive.
