What Causes the Abnormal Noise When Turning the Steering Wheel of a New Car?

Abnormal noise when turning the steering wheel of a new car is caused by friction between plastic components. Aging of the steering tie rod: If the ball joint of the steering tie rod ages, it can cause excessive play in the tie rod, leading to abnormal noise when turning the steering wheel. The steering tie rod ball joint needs to be replaced, but remember to perform a four-wheel alignment after replacement. Steering gear failure: If abnormal noise is heard when turning the steering wheel and the steering feel is noticeably uneven, it may be due to excessive wear of the steering gear's mating gears, causing excessive clearance. Replacing the steering gear can resolve this issue. Aging of the power steering belt: Improper tension or aging of the power steering belt. For mechanically hydraulic power-assisted steering systems, improper tension or aging of the drive belt can cause abnormal noise. Adjusting or replacing the belt can solve the problem.

What Causes Unstable Idle and Shaking in a Warm Car?

Unstable idle and shaking in a warm car are commonly caused by a dirty throttle body or throttle body malfunction. Causes of Shaking: Severe engine carbon buildup is the most frequent reason for car shaking, often due to an excessively dirty throttle body or excessive carbon deposits in the fuel injectors. When there's too much carbon buildup inside the engine, the gasoline sprayed by the cold start injector can be largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts. Ignition system issues—check the condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance in the ignition system or inadequate spark plug firing can also lead to such symptoms. Solutions: Clean the fuel system and check if the idle speed control valve has carbon buildup—it should be cleaned if necessary. Inspect the spark plugs for excessive carbon deposits and replace them if needed. Check the fuel pressure and replace components as required.

Will there be a record if a new car has a slight scratch repaired at a 4S shop?

A new car has a slight scratch, and there will be a record if it is repaired at a 4S shop. Repair methods: Minor scratches can be repaired with nail polish, forming a protective layer on the scratched area to prevent paint oxidation; moderate scratches require the use of a touch-up pen. The color of the touch-up pen should match the car's body color. Before touching up, clean the scratched area, wait for the primer to dry, then smooth it with water sandpaper, and finally apply the touch-up pen; severe scratches left unrepaired for a long time can easily rust and affect the surrounding good paint, so it is recommended to go to a professional repair shop for touch-up. Methods for cleaning paint stains: You can use a tar remover to dissolve dried tar, then wipe it dry with a cloth. If the car body has been exposed to the sun, the tar may have penetrated the paint surface due to sunlight and caused corrosion, requiring professional assessment of the damage; use sandpaper specifically designed for car cleaning to remove paint and oil stains, then restore the car's surface shine by waxing.

Is it necessary to replace the outer CV joint if it makes noise?

Whether to replace it depends on the specific situation. If the CV joint is making noise simply due to lack of lubrication, applying lubricant may solve the problem. However, if the CV joint is severely worn and the outer rubber component is completely damaged, replacement is necessary. More details about CV joints are as follows: 1. Introduction one: In the early stages of outer CV joint damage, the noise typically occurs only during turns, not when driving straight. Initially, the damage only causes noise without affecting driving performance. However, if not repaired or replaced in time, the condition will worsen until the CV joint fails completely, rendering the vehicle undrivable. Therefore, timely replacement is advisable. 2. Introduction two: The automotive CV joint, also known as the 'constant velocity joint,' is a crucial component in the vehicle's drivetrain system. Its function is to transmit the engine's power from the transmission to the drive wheels, enabling the car to move at high speeds.

How many times can I apply for a temporary license plate?

You can apply for a temporary license plate three times, but only one temporary plate can be issued at a time. The temporary plate can be extended for up to 21 days. The validity period of a temporary license plate generally does not exceed 30 days. There are four types of temporary license plates: temporary license plates for administrative jurisdictions, temporary license plates for cross-administrative jurisdictions, temporary license plates for testing purposes, and temporary license plates for special-type motor vehicles. New cars using temporary license plates must not exceed 15 days, and the owner should promptly apply for a formal license plate from the vehicle management authority. After the temporary license plate expires, certain penalties may be imposed. A temporary license plate for a car is a temporary vehicle travel certificate issued by the public security vehicle management department before the car is officially registered due to certain formalities.

What is the difference between dashed-line parking spaces and solid-line parking spaces?

The differences between dashed-line parking spaces and solid-line parking spaces are as follows: 1. Dashed-line parking spaces: Dashed-line parking spaces are subject to tidal or time restrictions. Parking within the allowed time period is the same as in solid-line parking spaces, but exceeding this time period will result in penalties. 2. Solid-line parking spaces: These are specifically designated for vehicle parking and can be used for long-term parking. Additional information: Regulations for temporary parking of motor vehicles on the road are as follows: 1. Parking is prohibited in sections with no-parking signs or markings, sections with separation facilities between motor vehicle lanes and non-motor vehicle lanes or sidewalks, as well as crosswalks and construction zones. 2. Parking is prohibited at intersections, railway crossings, sharp curves, narrow roads less than 4 meters wide, bridges, steep slopes, tunnels, and within 50 meters of these locations. 3. Parking is prohibited in front of bus stops, emergency stations, gas stations, fire hydrants, or fire stations (houses), and within 30 meters of these locations, except when using these facilities. 4. Doors must not be opened and passengers must not board or alight before the vehicle comes to a complete stop, and opening or closing doors must not obstruct other vehicles or pedestrians.
