What are the symptoms of a worn rear axle bushing?

Damage to the rear axle bushing can prevent it from functioning as a shock absorber, leading to vibrations and unusual noises in the chassis. Severe vibrations may affect the vehicle's driving stability and compromise ride comfort. The rear axle bushing acts as a flexible buffer between the axle and sleeve; its damage can cause collisions between the axle and sleeve, potentially resulting in misalignment between the rear wheels and wheel arches, leading to abnormal tire wear. Below are the steps for replacing the rear axle bushing: 1. Lift the vehicle. 2. Remove the two rear axle screws and oil pipe. 3. Use a specialized tool to extract the old bushing. 4. Apply grease to the new bushing's exterior for easier installation.

How to Handle ETC After Selling a Car?

After selling a car, if the original license plate number will continue to be used, you need to remove the ETC device and install it in the new car, then reactivate it once. If the license plate number will no longer be used, you need to cancel the original ETC device. How many ETCs can one person apply for: If a person owns only one car, they can only apply for one ETC. If a person owns multiple cars, they can apply for multiple ETCs. ETC usage precautions: The ETC transaction sensing area is 8 meters. When encountering a stationary vehicle ahead, to prevent the vehicle in front from having a faulty ETC device or no ETC device at all, maintain a distance of more than 10 meters to avoid automatic sensing and paying for the vehicle ahead. The ETC lane recognition speed is 20km/h. If the vehicle speed is too fast, the vehicle device information cannot be read, which will also result in a failed fee deduction. Unauthorized removal or movement of the OBU device, or detachment or loosening of the ETC electronic tag, will cause the electronic tag to fail. It can be sent to the bank where the ETC card was issued or the highway service office for testing. If the loosening or detachment is not caused by human factors, it only needs to be reactivated. When using a debit card to bind the ETC, insufficient balance will also result in a failed fee deduction. Follow the guidance of on-site staff to use the manual MTC lane and pass through by cash or card. An excessively thick car windshield may cause poor sensing. This is especially important for vehicles that have had their windshields replaced after an accident or for those who have modified their front windshields.

What Does It Mean When the ABS Light on the Dashboard Is On?

The ABS light on the dashboard indicates a malfunction in the vehicle's Anti-lock Braking System. During emergency braking, if the wheels lock up, the vehicle may lose control and skid, making it difficult for the driver to slow down or adjust the vehicle's trajectory, which poses significant safety risks. Common ABS Issues and Solutions: ABS Warning Light Stays On: Cause 1: The ABS wheel speed sensor's sensing area is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding wheel speed signal. This prevents the ABS computer from determining the wheel speed or calculating the wheel slip rate, thus failing to issue commands to adjust braking. Solution: Clean the dirt off the wheel speed sensor and adjust the gap between the sensor and the signal ring to restore normal function. Cause 2: Loose connections in the system wiring or poor contact in the ABS relay can lead to signal issues and system failure. The most common issue is a loose connection in the wheel speed sensor wiring, which will also show up as a wheel speed sensor signal error in the ABS computer's fault memory. Solution: Check the wiring connections and reconnect any loose parts. ABS Warning Light Intermittently Illuminates but Turns Off During Acceleration: Cause: When multiple vehicle electrical components are in use, the battery voltage may drop below 10.5V. As the engine speed increases and the voltage rises, the ABS light turns off. This could also be due to insufficient power supply voltage to the ABS system, such as poor terminal contact or grounding issues. Solution: Check the battery's specific gravity; inspect the charging system; examine the power supply (e.g., voltage relay or poor power contact).

Will the Car Lock Itself with the Key Inside?

For models equipped solely with "keyless entry" functionality, the vehicle can detect the presence of the key inside and will not automatically lock. Below is relevant information: 1. Many vehicles feature an automatic locking function when doors are closed. For instance, even entry-level BYD models have a 30-second auto-lock feature, which can sometimes be inconvenient. These functions can be enabled or disabled via the diagnostic computer at authorized 4S service centers. 2. For models without "keyless entry" functionality, if the vehicle is turned off and the doors are closed without the key, both the doors and trunk will automatically lock after a few minutes.

Is it necessary to file a registration for changing vehicle rims?

Modifying rims and altering tire sizes may result in failure to pass annual inspections and complete vehicle transfers. Therefore, changing rims also requires filing for registration. Before making modifications, it is advisable to consult the local vehicle management office for detailed information. Below are the specifics: 1. According to the "Motor Vehicle Registration Regulations," any changes to the body color, model, performance, purpose, or structure of a licensed motor vehicle, including replacing the frame, body, or engine, must be reported to the vehicle management office for registration of modifications. 2. If the replacement rims are of the same size, they may generally pass the annual inspection, provided the appearance does not change significantly, unless local policies are particularly strict. Upgrading to a high-quality set of rims can improve heat dissipation and reduce vehicle weight, offering significant visual impact both statically and dynamically, while also enhancing the vehicle's handling performance. Prior to modification, consulting the vehicle management office is recommended to avoid potential issues during annual inspections, which could lead to orders to revert to the original setup.
