How to Determine if a Car Wheel Bearing is Damaged?

Methods to determine if a car wheel bearing is damaged are as follows: 1. Open the car window and listen to see if the abnormal noise is coming from outside the vehicle. 2. After increasing the speed (when the humming sound is louder), shift the gear to neutral and let the vehicle coast, observing whether the noise comes from the engine. If the humming sound remains unchanged during neutral coasting, it is likely that the wheel bearing has an issue. 3. Temporarily stop the car, get out, and check if the temperature of the wheel axle is normal. The method is: touch each of the four wheel hubs with your hand to roughly feel if the temperature is consistent (when the brake shoe and pad gaps are normal, there is a temperature difference between the front and rear wheels, with the front wheels being slightly higher). If the difference is not significant, you can continue driving slowly to the repair station. 4. Use a lift to raise the car (after releasing the handbrake and shifting to neutral). If a lift is not available, use a jack to raise each wheel one by one. Manually rotate each of the four wheels quickly. When encountering a problematic axle, it will make a noise that is completely different from the others. This method makes it easy to identify which axle has an issue.

What is the meaning of a hood?

Hood (also known as the engine cover) is the most prominent body component and one of the parts that car buyers frequently inspect. The requirements for the hood are heat insulation, sound insulation, lightweight, and high rigidity. Structurally, the hood is generally composed of an outer panel and an inner panel, with heat insulation material sandwiched in between. The inner panel enhances rigidity, and its geometric shape is selected by the manufacturer, typically in a skeletal form. Below is relevant information: 1. Airflow guidance. Through guidance, air resistance can be decomposed into beneficial forces, increasing the front tires' grip on the ground, which is beneficial for the vehicle's driving stability. The streamlined appearance of the hood is basically designed according to this principle. 2. Protection of the engine and surrounding pipeline accessories. Under the hood are important components of the car, including the engine, electrical circuits, oil circuits, braking system, and transmission system, etc., which are crucial to the vehicle. By improving the strength and construction of the hood, adverse effects such as impact, corrosion, rain, and electromagnetic interference can be fully prevented, ensuring the normal operation of the vehicle. 3. Aesthetics. The exterior design of a vehicle is a direct reflection of its value. As an important part of the overall appearance, the hood plays a crucial role in being visually pleasing and embodying the concept of the entire car.

Can a temporary ID card be used to take the Subject 4 exam?

A temporary ID card can be used to take the Subject 4 exam, as it holds the same validity as a regular ID card. Simply visit any public security bureau, submit your household registration booklet, a recent one-inch black-and-white photo without a hat, and pay a fee of 10 RMB for the document. You can obtain the temporary ID card on the same day. The Subject 4 exam consists of 50 questions, primarily in the form of case studies, images, and animations. The total score is 100, with a passing score of 90. Subject 4, also known as the theoretical exam for drivers, is part of the motor vehicle driver's license assessment. After the implementation of the Ministry of Public Security's Order No. 123, the Subject 3 exam was divided into two parts: the road test and an additional safety and civilization knowledge test, commonly referred to as "Subject 4," which assesses "driving ethics." Since this test is conducted after Subject 3, it is colloquially called the Subject 4 exam. Officially, there is no such term as Subject 4. If you fail the Subject 4 exam, you do not need to retake the previously passed subjects (Subject 1, Subject 2, Subject 3). You can schedule a retake on your own without any additional fees. There are no restrictions on the number of retakes, but the driving skill test permit is valid for three years. If the applicant does not complete the exam within this period, the results of any passed subjects will become invalid.

What to Do If ETC Card Is Lost?

ETC card replacement method: The vehicle owner should bring their ID card, the original and a copy of the vehicle registration certificate to the bank counter to apply for card change, replacement, or reissuance. The installation process of the ETC device is as follows: Upon receiving the device, first check if the ETC card and the electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU. The red light will briefly turn on, and the OLED screen will display "Tag Invalid" or "Please Insert Card," indicating the device is functioning normally. Clean the front windshield to ensure the glass surface is smooth, clean, and dry. Then peel off the adhesive backing of the OBU and stick it to the installation position. Press firmly for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front side facing the driver and the back side facing the windshield. The chip should be inserted into the OBU device. ETC device activation method: Insert and remove the ETC card twice in succession until the electronic tag screen displays "Bluetooth On." If "Tag Invalid" appears when inserting and removing the card twice without the electronic tag attached, this is normal and does not affect activation. Alternatively, press the button on the top of the electronic tag to enable Bluetooth directly. Turn on the mobile phone's Bluetooth and open the corresponding mobile app (usually a download QR code is provided on the electronic tag), then enter the device activation interface. Click "Connect Device" and wait patiently for the "Connection Successful" prompt. Once connected, upload a photo of the vehicle's front to complete the activation.
