What causes the sound of metal scraping the ground when the car is running?

There are several reasons why a car may produce a sound similar to metal scraping the ground: 1. First, if the underbody cover becomes loose, the underbody guard plate may continuously scrape against the ground while driving, creating a noise resembling dragging metal. 2. Secondly, if the ceramic filter inside the catalytic converter breaks, the shattered ceramic pieces may continuously collide with the metal shell of the catalytic converter during vehicle movement, resulting in various metal knocking and dragging sounds. 3. Additionally, similar noises can be caused by loose brake discs, transmission abnormalities, or excessive wear of the half-shaft.

What Causes the Zizzing Sound at Low Speed?

This noise could be coming from the suspension system or the braking system. It is recommended that car owners visit a 4S shop for inspection. Below are some related explanations: 1. Suspension Aging Issue: The suspension is a crucial component of a car. Over time, the suspension may produce abnormal noises. There are many rubber bushings in the suspension, which may age after prolonged use, leading to noises during driving. When the suspension bushings age, they need to be replaced to resolve the noise issue. 2. Shock Absorber Problem: The shock absorbers of a car may also produce abnormal noises after long-term use. Shock absorbers are wear-prone parts and need replacement over time. Some cars may experience oil leakage in the shock absorbers after prolonged use, which requires replacement. 3. Braking System Malfunction: The braking system includes the vacuum booster pump, master cylinder, and wheel cylinders (commonly seen as brake calipers). If the wheel cylinders have retraction issues, the car may produce abnormal noises at low speeds. The braking system is vital for driving safety. If any malfunction occurs, immediate repair is necessary.

What does the car menu button mean?

menu means "menu", which is a content list. The functions of the menu button vary among different car models, and some models do not have a menu button, instead using a SET button. Generally, clicking the menu button will display all the setting lists in the current mode on the car's infotainment system, making it convenient for the driver to adjust settings. Below are some related introductions: 1. The location of the menu button: The menu button in a car usually appears on the multifunction steering wheel controls or the center console controls. 2. The function of the steering wheel menu: For example, the lever on the left side of the multifunction steering wheel is generally used for light adjustments (including headlights, front and rear fog lights, and turn signals). Additionally, pressing the menu button allows for adjustments to many vehicle functions. 3. The function of the center console menu: The menu button on the center console controls is mostly used as a sound effect setting button. A short press, combined with the knob on the right, can adjust the desired sound quality and tone. However, in most cases, this button represents the main menu, and its use should be determined based on the specific situation.

What is the difference between white and yellow lines?

The differences between white and yellow lines are as follows: 1. Double yellow lines are generally the central dividing lines on roads with four or more lanes. If both yellow lines are solid, it indicates that crossing the line or overtaking is strictly prohibited. A single yellow line is usually the central dividing line on two-lane roads. A single yellow line can be either solid or dashed; when dashed, crossing the line for overtaking is allowed, but when solid, it is not. Solid lines often appear at intersections. 2. A solid white line is the lane divider for same-direction traffic, typically a single line, and crossing or overtaking is not allowed. A dashed white line is generally the lane divider for same-direction traffic, allowing crossing or overtaking. 3. If it is a solid yellow line, it indicates a no-parking marking, meaning parking is not allowed in this section, including temporary parking. If it is a dashed yellow line, temporary parking is allowed, but long-term parking is not. Violators will be fined 100 yuan and receive 3 penalty points. 4. A solid white line beside the road is the boundary line for the motor vehicle lane, separating it from non-motorized vehicle lanes or sidewalks. It is not directly related to whether parking is allowed.

How to Identify the Production Year of Car Glass?

There is a code located at the bottom left or right corner of the car window glass, with a digit and several small black dots in the last or second-to-last row. The digit represents the production year of the glass, indicating the last digit of the year, while the small black dots denote the production month. More detailed information is as follows: 1. Many car owners are aware that the markings on car glass include the production date, especially for those involved in appraising or purchasing used cars. Identifying the production date of car glass helps determine whether the glass has been replaced. 2. The production date of car glass can be determined by examining the code at the bottom left or right corner of the window glass, specifically the digit and small black dots in the last or second-to-last row. First, the digit indicates the production year, representing the last digit of the year. The small black dots signify the production month. Upon closer inspection of other vehicles' glass, you may notice that some have the black dots before the digit, while others have them after. If the black dots are before the digit, subtract the number of dots from 7. If the black dots are after the digit, subtract the number of dots from 13. The result will be the production month. Some glass may also have additional large black dots following the production year and month, which indicate the specific week of the month. For example, 5 dots represent the first week, 4 dots the second week, 3 dots the third week, and so on.

What Causes Steering Wheel Noise When Turning?

Steering wheel noise during rotation can be caused by various factors such as aging of the tie rod end ball joint, loose stabilizer bar bushings, dirty power steering fluid, or lack of lubrication in the shock absorber top bearing. Below are detailed explanations for the causes of steering wheel noise when turning: 1. Lack of lubrication in shock absorber top bearing: If the noise seems to come from outside the vehicle when turning the steering wheel, it might be due to insufficient lubrication in the shock absorber's top bearing. You can verify this by opening the hood and listening if the noise originates from the shock absorber top mount area. Applying grease may solve the issue, but if the noise persists, replacement is necessary. 2. Loose stabilizer bar bushings: If the noise isn't from the shock absorber bearing, check the stabilizer bar bushings for looseness or damage. Loose or damaged bushings will not only cause noise during steering but also when driving over rough roads. Looseness can sometimes be fixed by adding shims, but damaged bushings require replacement. 3. Dirty power steering fluid: Contaminated power steering fluid increases system pressure, leading to a humming noise from the power steering pump. The solution is to replace the power steering fluid promptly. 4. Aging tie rod end ball joint: Worn tie rod end ball joints can cause both steering wheel vibration and noise. This typically requires replacement of the tie rod end followed by a four-wheel alignment.
