The wheel hub can be identified through the markings on the tire. Below is relevant information about the wheel hub: 1. Wheel hub bearing: In the past, the wheel hub bearings of cars were mostly used in pairs with single-row tapered roller or ball bearings. With technological advancements, cars have widely adopted wheel hub units. 2. Application scope of bearing units: The application scope and usage of wheel hub bearing units have been increasing and have developed to the third generation: The first generation consists of double-row angular contact bearings. The second generation has a flange on the outer raceway for fixing the bearing, allowing the bearing to be simply placed on the wheel axle and secured with a nut, making car maintenance easier. The third-generation wheel hub bearing unit combines the bearing unit with an anti-lock braking system. The wheel hub unit is designed with inner and outer flanges; the inner flange is bolted to the drive shaft, and the outer flange integrates the entire bearing assembly.

What are the types of Mobil engine oil?

Mobil engine oils are categorized into Mobil Super, Mobil 1, and Mobil Delvac. The functions and precautions of engine oil are as follows: Functions of engine oil: Separate the surfaces of relatively sliding parts to reduce wear. Bring heat back to the oil tank and then dissipate it into the air to help the radiator cool the engine. Circulate carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank, and flush away dirt generated on the working surfaces of parts through the flow of lubricating oil. Precautions for changing engine oil in cars: Drain the oil when it is hot, as the oil flows better; Fill to the level indicated by the dipstick; Choose oil products based on driving environment, driving frequency, and the requirements of the vehicle's engine itself.

What causes fog on the outside of the windshield that cannot be wiped off?

The fog on the windshield that cannot be blown away may be caused by a leak in the glass interlayer seal, allowing water vapor to enter the interlayer of the windshield. The solution is to locate the leak in the windshield seal, blow out the water vapor from the windshield, and reseal the windshield. There are three solutions to windshield fogging: Solution 1: Use the external air circulation + direct airflow to the windshield + increase temperature + increase fan speed + do not turn on the AC. This can solve over 90% of windshield fogging issues. The advantage is that it does not increase fuel consumption, but the downside is that it may cause discomfort. Solution 2: Turn on the AC, regardless of internal or external air circulation, adjust temperature and fan speed appropriately, and direct airflow as desired. This can solve almost all fogging issues. The advantage is comfort and simplicity, but the downside is increased fuel consumption. Solution 3: Apply a windshield defogging agent or detergent to the inner windshield, which can prevent fogging for a period of time. The advantage is that you do not need to use warm air for defogging, but the downside is that it requires proper application, may have odors, only lasts for a limited time, and needs to be reapplied.

Can I Make a U-Turn to the Left at a Red Light Ahead?

No, generally you cannot make a U-turn when the left-turn red light is on. Vehicles can make a U-turn at locations where there are no signs or markings prohibiting U-turns or left turns, but they must not obstruct the normal passage of other vehicles and pedestrians. More details are as follows: U-turns without crossing the stop line: If there is a dashed line or a turning junction near the guardrail when the light turns red, a U-turn can be made at the red light. However, if the vehicle has reached the stop line, a U-turn is not allowed. If the vehicle has not yet reached the stop line and there is a dashed line on the ground, a U-turn can be made even if the light is red. U-turns are not allowed on the side with a solid line. U-turns without crossing the stop line when there is a U-turn signal: Although traffic regulations state that you do not need to observe the traffic signal when making a U-turn without crossing the stop line, road conditions vary in each province of China. Therefore, it is best to follow the traffic light instructions when making a turn.
