The possible causes for this issue may include wheel alignment, tire dynamic balance, friction coefficient of new tires, improper installation of chassis components during repair, and deformation of front bearing balls. Below are the reasons and solutions for steering wheel shaking in cars: 1. Steering wheel shaking when encountering bumpy roads: While driving, if the tie rod ball joint is loose or the rubber sleeve at the joint falls off, or if the tires become irregular due to wear, the car should be sent to a professional repair shop for inspection and replacement of damaged parts. 2. Sudden steering wheel shaking during high-speed driving: Excessive or frequent braking may cause the brake discs and brake pads to overheat and deform when cooled, leading to steering wheel shaking. Generally, replacing the brake discs and brake pads can resolve the symptoms. 3. Steering wheel shaking when stationary: Many car owners solve this by increasing the idle speed or lightly pressing the accelerator during startup to raise the RPM and avoid resonance points of the body, steering, and transmission components. Some older cars develop shaking over time, mainly due to aging of engine mounts and rubber components at connections. Replacing the corresponding parts usually solves the problem. 4. Shaking when turning the steering wheel: Shaking when turning the steering wheel may be caused by the timing belt being too loose or too tight. This issue often occurs in vehicles with hydraulic power steering. While not a major problem, it still requires timely repair.

What Causes Battery Bulging?

Automotive battery bulging can occur due to the following reasons: 1. In valve-regulated sealed lead-acid batteries during charging operations, especially in series-connected battery packs, overcharging can lead to poor internal gas recombination in low-quality batteries, resulting in bulging. To prevent this, when using valve-regulated sealed lead-acid batteries, it is advisable to reduce the float charge voltage and charging current, and avoid using poor-quality batteries. 2. Setting the float charge voltage too high with a large charging current accelerates oxygen evolution on the positive plate, which cannot recombine quickly enough at the negative plate. Additionally, the battery's internal temperature rises rapidly. If venting is delayed, the pressure may build up to a point where the valve-regulated sealed lead-acid battery bulges or deforms.

Can I directly replace my driver's license if it is lost?

You cannot directly replace your driver's license if it is lost. To replace your driver's license, you need to provide the original license. If you do not have the original license, you must first apply for a replacement before you can proceed with the renewal. Renewal process: The motor vehicle driver should bring the required materials and apply for a license replacement at the vehicle management office where the driver's license was originally issued. The vehicle management office will process the replacement within one working day after approval. License renewal and inspection must meet the following conditions: Holders of large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, or large truck driver's licenses must have no demerit points in the current scoring cycle, or holders of other types of driver's licenses must have fewer than 12 demerit points in the current scoring cycle; Holders of large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, or large truck driver's licenses who have demerit points in a scoring cycle, or holders of other types of driver's licenses who have been involved in a traffic accident resulting in death and bear equal or greater responsibility but have not had their license revoked, must have completed the inspection education; The applicant must have no pending road traffic safety violations or traffic accidents; The applicant's physical condition must meet the driving license requirements; The driver's license must not be under any legal seizure, detention, suspension, revocation, cancellation, or withdrawal.

How to Deal with Oil Stains on Car Windows?

Oil stains on car windows are generally difficult to clean with regular glass cleaner. You can purchase specialized oil film removers or toothpaste containing abrasive particles. More information about oil stains on car windows is as follows: 1. During driving, incompletely burned residual oil from the exhaust pipes of vehicles on the road adheres to the car glass, and over time, these oil residues turn into an oil film. 2. When the glass is dry, the oil film is hard to detect with the naked eye. On rainy days, the windshield becomes blurry, and when the wipers are activated, a thin layer of white mist appears, severely impairing visibility. This poses a significant safety hazard when illuminated by lights.

What are the solutions for ignition failure caused by parking brake malfunction?

The solutions for ignition failure caused by parking brake malfunction are: 1. Brake shoe failure, abnormal or irregular wear, requiring replacement of brake pads; 2. Insufficient brake fluid, simply replace the brake fluid; 3. Spark plug failure leading to increased ignition gap, replace the spark plug; 4. ABS system failure, abnormal wheel speed sensor or wiring, check if the battery is low on power and recharge it promptly. The functions of the parking brake are: 1. The AUTOHOLD automatic parking function provides accurate parking force through the slope sensor controlled by the controller; 2. When driving in urban areas facing frequent traffic jams, enabling the AUTOHOLD automatic parking function prevents stalling when stopping and starting again.

Is Wheel Balancing Necessary When Replacing New Tires?

Wheel balancing is necessary when replacing new tires, as prolonged use may cause the balancing weights to fall off, resulting in an imbalance in the tire's weight distribution. To check, lift the tire off the ground and spin it at high speed. Observe whether the tire comes to rest in the same spot or at a diagonal position. If the tire stops randomly in any direction, balancing is not required. However, if it consistently stops in the same spot, wheel balancing is needed. Tires are circular elastic rubber products mounted on various vehicles or machinery, typically installed on metal rims. They support the vehicle body, absorb external shocks, maintain contact with the road, and ensure driving performance.

Will driving in a vest result in penalty points?

Driving in a vest is not explicitly prohibited by law and generally does not constitute a violation. However, drivers must not be shirtless or wear slippers or high heels while operating a vehicle. Below are some important driving precautions: Avoid wearing chest accessories while driving: During sudden braking, the body is thrust forward by inertia, and the seatbelt exerts significant pressure on the body. If there are large, hard accessories on the chest, they can cause severe injuries such as sternum fractures. Slow down and look both ways at intersections: Develop the habit of slowing down and checking left and right when approaching intersections. Observe the traffic conditions on the cross lanes and proceed only when it is safe. Maintaining a calm and composed mindset while driving is crucial—anticipate situations in advance and handle emergencies with composure. Slow down and check carefully when turning: Whether in urban or rural areas, always slow down when turning. Make it a habit to reduce speed further and check the bicycle lanes and pedestrian walkways. Yield to electric bikes in bicycle lanes and pedestrians on walkways. When making a right turn in the city, give way to pedestrians and electric bikes, ensuring no unexpected incidents before proceeding slowly. Maintain a safe following distance: Many traffic accidents are directly related to unsafe following distances. Always pay attention to the distance between vehicles while driving. Reduce speed and use the horn as a warning when turning or in crowded areas.
