The causes of excessive heat in the drive axle include: 1. Deterioration of gear oil, insufficient oil quantity, or failure to meet the required specifications; 2. Over-tightened bearing adjustment; 3. Excessively small adjustment of gear meshing clearance and the clearance between planetary gears and axle shafts; 4. Insufficient clearance between thrust washers and the driven gear of the main reducer; 5. Over-tightened oil seals and poor lubrication of moving pairs and bearings, leading to dry (or semi-dry) friction. The drive axle is a mechanism located at the end of the transmission system that can alter the speed and torque from the gearbox and transmit them to the driving wheels. The drive axle consists of the main reducer, differential, wheel transmission device, and drive axle housing, among other components.

Why does the dash cam always show low battery?

If the dash cam displays low battery, it may be caused by poor power contact. Here is more information about dash cams: 1. Solutions: Check the wiring, replace the wiring, and inspect for poor contact or disconnection of the power cable. 2. How to conserve built-in battery power: It is recommended to power the dash cam through the cigarette lighter or reading light, rather than relying solely on the built-in battery. Also, ensure that the dash cam automatically shuts down a few seconds after the vehicle is turned off. However, sometimes the cigarette lighter socket may become loose, leading to the depletion of the built-in battery.

Where Can I Check Tire Pressure?

Places where you can measure tire pressure include auto repair shops, 4S stores, and other locations equipped with tire pressure gauges. According to the international GBT2978-2008 standard, the recommended tire pressure for standard tires is 2.4-2.5 bar; for reinforced tires, it is 2.8-2.9 bar. The maximum pressure should not exceed 3.5 bar. Tire pressure monitoring automatically checks the tire pressure in real-time while driving and alerts the driver in case of leaks or low pressure to ensure driving safety. There are three common methods of tire pressure monitoring: Direct Tire Pressure Monitoring: This system uses pressure sensors installed in each tire to directly measure the tire pressure. The pressure data is transmitted wirelessly from inside the tire to a central receiver module, which then displays the pressure readings for each tire. The system automatically alerts the driver if the tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that tire to become smaller, making it rotate faster than the other tires. By comparing the rotational speed differences between tires, the system monitors the tire pressure. Indirect tire pressure monitoring systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Tire Pressure Monitoring System (TPMS) Overview: This system combines the advantages of both direct and indirect monitoring. It is equipped with direct sensors in two diagonally opposite tires and includes a four-wheel indirect system. Compared to a fully direct system, this hybrid approach reduces costs and overcomes the limitation of indirect systems, which cannot detect low pressure in multiple tires simultaneously. However, it still cannot provide real-time pressure data for all four tires as effectively as a fully direct system.

Is there a grace period for vehicle inspection if it's overdue by a few days?

There is no grace period for overdue vehicle inspections. Here are the relevant impacts of an expired vehicle inspection: 1. Vehicle loss counts as 'lost for nothing': If the vehicle inspection is overdue, according to the insurance company's auto insurance policy terms, the policy only covers qualified and legal vehicles. 2. No insurance coverage for accidents: If an accident occurs with a vehicle whose inspection is overdue, the insurance company has the right to refuse compensation. 3. Fines: According to Article 95 of China's 'Road Traffic Safety Law', if a driver is found operating a motor vehicle with an overdue inspection, they will not only be fined 200 yuan and receive 3 demerit points, but the vehicle will also be temporarily impounded.

What does it mean when the ESC system needs to be checked?

Generally, it is caused by insufficient tire pressure, or faults in the ABS sensor or wiring harness. The specific cause needs to be diagnosed with a computer. Here is more information about the ESC system: 1. Introduction to ESC: The Electronic Stability Control system is a new active safety system for vehicles, which is an extension of the Anti-lock Braking System (ABS) and Traction Control System (TCS) functions. 2. Function of ESC: Electronic Stability Control is an active safety technology that assists drivers in controlling the vehicle. It automatically corrects the instability of the vehicle body, helping to prevent accidents.

How Often Should Power Steering Fluid Be Replaced?

It is recommended to completely replace the power steering fluid in a car once a year or every 20,000 kilometers. During the replacement process, avoid running the engine without fluid for an extended period, as this can damage the power steering pump. Below is more information about power steering fluid: 1. Function: Power steering is a comfort-enhancing technology in vehicles that automatically provides steering force when the driver turns the wheel, reducing the effort required. Power steering fluid is a medium oil added to the power steering system, serving to transmit steering force and provide cushioning. 2. Nature: Power steering fluid, also known as power steering oil, is essentially a type of hydraulic oil. Compared to brake fluid, power steering fluid has higher viscosity, poorer fluidity, and can corrode the seals in the braking system.
