When driving, the car's wheels may wobble, and the overall vehicle vibration intensifies; unusual noises may occur; rolling becomes less smooth, and there is a noticeable decrease in power. Here are specific details about rear wheel bearing damage: 1. Methods to determine if it's damaged: You can accelerate the car and then coast in neutral. If the humming noise remains unchanged, it indicates a damaged rear wheel bearing. 2. Causes of rear wheel bearing damage: Broken or rusted components, foreign object intrusion, or misaligned rollers can lead to damage. Prolonged exposure to acidic liquids and moisture can also cause rust on components; poor lubrication—if there's insufficient grease between the rollers and the raceway, dry friction can occur, resulting in metallic grinding noises; clearance issues—there is an appropriate gap between car parts, and when the distance between the rollers and raceway decreases, it can cause friction, heat, and eventually bearing seizure.

How to Solve Engine Knocking?

Solutions for engine knocking: 1. Reduce the ignition advance angle; 2. Use gasoline with the specified octane rating; 3. Clean carbon deposits from the combustion chamber; 4. If knocking occurs while climbing a hill, promptly shift to a lower gear; 5. When starting the car, do not shift into direct drive too early; 6. If knocking occurs due to excessive engine load, close the throttle slightly. Under certain conditions, the combustion in a gasoline engine can become abnormal, with the pressure curve showing high-frequency, large-amplitude fluctuations. The dp/dt value near the top dead center fluctuates sharply, reaching as high as 0.2 MPa/μs. At this point, the flame propagation speed and the shape of the flame front change drastically. This phenomenon is called detonation, and knocking is the external manifestation of detonation.

What does it mean when the vehicle maintenance reminder light comes on?

When the vehicle maintenance reminder light comes on, it indicates that the car requires maintenance. As the vehicle reaches a certain mileage, the onboard computer detects that maintenance is needed, and the dashboard light will illuminate to alert the owner. To ensure the vehicle's reliability, it is recommended to perform maintenance immediately when the reminder light appears. Routine maintenance typically involves changing the engine oil, other fluids, oil filter, air filter, consumable rubber parts, and gradually wearing components. In addition to replacing these parts, a thorough inspection of the vehicle is also necessary. Owners can schedule maintenance based on their specific needs. Regular car maintenance helps maintain optimal performance, reduces the likelihood of repairs, and ensures driving safety, making timely maintenance very important.
