When a car bearing is damaged, it is generally not necessary to replace both bearings at the same time. Here are the relevant details: 1. Bearing Damage: This is usually caused by internal wear or lack of lubrication. The specific fault point can be confirmed through a test drive. If the bearing lubricant has not been lost, it does not need to be replaced regularly within the bearing's lifespan and can be used for its entire service life. 2. How to Determine Bearing Damage: You can try driving for half an hour and then lightly touch the suspected damaged wheel hub area with the back of your hand after getting out of the car. If the bearing is damaged, it will generate significant heat and may even feel hot to the touch.

What is the normal tire pressure for a Cadillac?

The normal tire pressure for a Cadillac is between 2.3 and 2.5 bar, which can be directly monitored through the dashboard for any changes in tire pressure. Below are some important considerations regarding tire pressure: Low tire pressure: If the tire pressure is too low, the contact area between the tire and the ground increases, leading to greater deformation of the tire body and potential cracking on the tire sidewalls. If the car is driven at high speeds, the tires can heat up quickly, accelerating rubber aging and reducing the tire's lifespan. Additionally, encountering road protrusions may increase the risk of a tire blowout. High tire pressure: If the tire pressure is too high, the tire cords may undergo excessive stretching and deformation, reducing the contact area with the ground and diminishing the tire's elasticity. This increases the load on the car during driving and may negatively impact ride comfort.

What is the difference between blue license plates and yellow license plates?

The differences between blue license plates and yellow license plates include different driver's license requirements, different highway toll standards, and different restricted traffic zones. Below are detailed explanations of the differences between blue and yellow license plates: Different driver's license requirements: Yellow license plate vehicles require a Class B driver's license to operate, while blue license plate vehicles only need a Class C driver's license. Different highway toll standards: In terms of highway tolls, blue license plate vehicles are charged lower fees, while yellow license plate vehicles generally incur higher charges. Factors such as the size and weight of yellow license plate vehicles contribute to the relatively higher costs. Different restricted traffic zones: In some cities, blue license plate vehicles are not subject to traffic restrictions and can travel freely. However, yellow license plate vehicles must travel during specific time periods and may even require a traffic permit.

How to adjust the time on the Mazda Atenza?

Locate the SET button on the steering wheel, press and hold the SET button to adjust the time. Detailed introduction of the Mazda Atenza is as follows: Configuration: The Atenza emphasizes convenience in configuration, hence it is equipped with the CF-Net new multifunctional human-machine interface system, which centralizes all configuration controls on the steering wheel. This allows the driver to keep their hands on the wheel without shifting their gaze, thereby enhancing driving safety. In high-end models, an 8-probe parking assist system is added both front and rear, providing the driver with maximum convenience. Power: The Atenza uses the newly developed MZR 2.5L gasoline engine to replace the previous MZR 2.3L engine. The MZR 2.5L engine increases the cylinder bore and stroke, reduces the cylinder spacing, and lightens the piston. It also improves the flow of intake and exhaust ports to enhance torque in the practical range, achieving a more linear acceleration feel and precise response performance.

What Are the Major Causes of Engine Vibration?

Automobile ignition system failure can cause the car to vibrate at idle. Generally, check the car's spark plugs. If the spark plugs are found to be faulty, replace them promptly. The main causes of car engine vibration include ignition system issues, poor fuel quality, engine carbon buildup, and unstable oil pressure. Below are detailed explanations regarding car engine vibration: Ignition System Issues: Automobile ignition system failure can cause the car to vibrate at idle. Generally, check the car's spark plugs. If the spark plugs are found to be faulty, replace them promptly. Poor Fuel Quality: This is the most common issue encountered during daily driving. Poor fuel quality can easily affect engine performance, leading to engine vibration at idle. Therefore, when refueling your car, always go to reputable gas stations to ensure the use of quality fuel. Engine Carbon Buildup: When engine carbon buildup becomes severe, it naturally leads to vibration, along with symptoms like reduced power. Timely treatment of car carbon buildup can resolve these issues.

Which gear should be used throughout the entire Subject 3 driving test?

Subject 3 gear usage is divided into starting gear, U-turn gear, and intersection turning gear. Below is a detailed introduction about gear usage: Starting gear: In the Subject 3 test, regardless of when, as long as you start after stopping, you must use 1st gear. U-turn gear: The Subject 3 assessment standards clearly stipulate that 1st gear must be used when making a U-turn. After hearing the U-turn voice command, first reduce speed and gradually shift to 1st gear. After completing the U-turn, immediately press the accelerator to increase speed, gradually shifting from 1st gear to 2nd gear and then to 3rd gear. Intersection turning gear: All intersection turns must be made in 2nd gear. When hearing the intersection turning command, lightly press the brake to reduce speed to 20km/h, then fully depress the clutch and shift to 2nd gear.
