Shock absorber failure manifests as follows: 1. Shock absorber oil leakage: Normally, the exterior surface of a shock absorber is dry and clean. If oil seeps out, it indicates that the hydraulic oil inside the shock absorber has escaped from the upper part of the piston rod, which means the shock absorber is essentially failing; 2. Abnormal noises: When the car passes over bumpy roads or speed bumps, if a particular wheel makes noise, it suggests that the shock absorber on that wheel has poor damping performance or has failed; 3. Body tilt: When the car turns, there is a noticeable increase in body roll, and in severe cases, even skidding may occur. This is mainly due to the shock absorber's damping force being too small to effectively suppress the spring compression; 4. No surface temperature: After driving on rough road conditions for a while, touch the outer shell of each shock absorber to feel its temperature. Normally, the shock absorber shell should be warm. If a particular shock absorber shell has no temperature, it indicates that the shock absorber is damaged.

Why can't the Borgward BX5 trunk lock?

The reasons why the trunk cannot be locked include the use of overly stiff spring rods, mismatched closing limit rubber blocks and locking mechanisms, trunk control circuit failure, and trunk hydraulic support rod failure. Methods to open the trunk: Directly use the remote key to open: The car key has a remote control function, simply press the trunk unlock button to open it; Open from inside the car: There is a handle with a trunk lid icon near the driver or on the floor, pulling the handle will unlock the trunk. How to solve the problem of the trunk not closing: For situations where the trunk cannot be closed, most of what can be done is to try to close it with more force, but force will only worsen the damage. There are many reasons why the trunk cannot be locked, and the vehicle should be taken to a repair shop for inspection.

Why does a truck lack power and fail to accelerate when refueling?

If a vehicle exhibits symptoms of poor acceleration, there can be numerous underlying causes. For instance, the clutch disc may not be engaging properly, the engine may be over-fueled, or there could be an oxygen sensor malfunction. Below are more detailed explanations: 1. Most trucks are equipped with manual transmissions: Manual transmissions have a clutch system where the clutch pressure plate is mounted on the engine flywheel, and the clutch disc transmits power when pressed tightly by the pressure plate. If the clutch disc fails to engage fully, it will slip during acceleration, preventing complete power transfer to the transmission, resulting in sluggish acceleration. 2. There are two oxygen sensors: One is located at the end of the exhaust manifold, and the other at the end of the catalytic converter. The oxygen sensors monitor the oxygen content in the exhaust gases. They send signals to the ECU (Engine Control Unit), which adjusts the air-fuel ratio based on these signals. If an oxygen sensor is faulty, it may fail to send accurate signals to the ECU or provide incorrect feedback.

Can an expired motorcycle still undergo inspection?

Motorcycles that have been expired for two years can still undergo annual inspection. However, if a motorcycle has not been inspected for three years, it will be forcibly scrapped. After passing the annual inspection, the motorcycle can be transferred. Below are the relevant details: Relevant regulations: According to Article 16 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China": Motor vehicles shall undergo safety technical inspections within the following periods from the date of registration: (1) Passenger vehicles for commercial use must be inspected once a year within 5 years; after exceeding 5 years, once every 6 months. (2) Trucks and large or medium-sized non-commercial passenger vehicles must be inspected once a year within 10 years; after exceeding 10 years, once every 6 months. (3) Small and mini non-commercial passenger vehicles must be inspected once every 2 years within 6 years; after exceeding 6 years, once a year; after exceeding 15 years, once every 6 months.

Is It Necessary to Wrap a Plastic Steering Wheel with Genuine Leather?

It is necessary to wrap a plastic steering wheel with genuine leather, as installing a genuine leather steering wheel cover provides a much better driving feel compared to the original plastic steering wheel. The genuine leather cover offers smoother handling. Below is an extended introduction: 1. The significance of wrapping with genuine leather: If the original steering wheel does not come with genuine leather and the grip feels unsatisfactory, you can choose to cover it with a steering wheel protector. This enhances the tactile experience when your palms contact the wheel and reduces wear on the steering wheel. However, there are a few points to consider when purchasing a steering wheel cover, as improper selection may affect driving safety. 2. The steering wheel as a critical component of the steering system: Any minor flaw can lead to serious consequences. Therefore, when selecting a steering wheel cover, it is essential to choose one that matches the original steering wheel's dimensions. If the cover is too large compared to the original steering wheel, it may slip during turns or when the wheel returns to center, resulting in insufficient steering response.

Why is there a knocking sound when releasing the clutch after shifting gears?

Clutch noise is relatively complex and difficult to accurately diagnose without an on-site inspection. First, the source of the noise should be identified. It is recommended to check whether the clutch pressure plate and release bearing produce noise due to issues such as excessive clearance or deformation when the pressure plate engages. For a more reliable diagnosis, it is advisable to visit a 4S dealership and have a technician test drive the vehicle. Below is additional information: 1. The function of a car clutch: To ensure smooth vehicle starting; to facilitate shifting between different transmission gears to adapt to changing driving conditions; to prevent overload in the drivetrain; and to significantly reduce torsional vibration impacts from the engine, thereby extending the lifespan of transmission gears. 2. A friction clutch should meet the following basic requirements: It must be capable of transmitting the maximum torque produced by the engine with some margin for additional torque. It should fully disengage when separated, engage smoothly, and have good heat dissipation capabilities. The rotational inertia of the driven parts should be as small as possible. This makes it easier to change the speed of the parts connected to the transmission input shaft when disengaging the clutch to shift gears, thereby reducing gear impact.

How to Remove Minor Scratches on a Car?

Methods for removing minor scratches on a car are as follows: 1. Toothpaste: Use toothpaste to polish and remove very light scratches. 2. Waxing and polishing: If the primer is not exposed, waxing and polishing will suffice. 3. Touch-up paint pen: If the primer is visible, use a touch-up paint pen to repair it. Methods to prevent car scratches are as follows: 1. Wash the car with running water, from top to bottom: Use running water when washing the car, not 'stagnant water.' 2. Be careful when unlocking to avoid scratches: When inserting the key, be cautious, especially at night—don’t rely on feel or insert it hastily to avoid leaving scratches on the car’s lock holes or door handles. 3. Drive at a moderate speed to avoid flying debris: When driving, avoid excessive speed—it’s not only unsafe but also likely to kick up small stones or sand, which can damage the car body.
