A leaking drive shaft of a small car needs to be replaced. Reasons for leakage: The rubber sealing ring is subjected to alternating cold and warm temperatures over time, causing the sealing ring to lose a large amount of plasticizers and softeners, leading to corrosion, aging, and hardening. Initially, it seeps oil, and gradually starts dripping oil. Over time, the sealing ring may crack. Causes and measures for leakage: Leakage is often caused by loose clamps. Tightening the screws is ineffective, as leakage will recur over time. To completely resolve this issue, the corresponding parts of the drive shaft and transfer case need to be disassembled and reassembled properly. Causes and measures for leakage: If the oil seal is damaged, replace the oil seal.

How to Reduce Tire Noise in the Tenth-Generation Civic?

Methods to reduce tire noise in the tenth-generation Civic: 1. Replace with noise-reducing tires; 2. Perform sound insulation treatments on the vehicle, including undercoating, engine compartment insulation, and cabin insulation, all of which can help reduce tire noise. Tire noise is generated by the friction between the tires and the road surface when the vehicle is driving at high speeds, and its level depends on road and vehicle conditions—the worse the road condition, the louder the tire noise. In terms of body dimensions, the tenth-generation Civic measures 4649 mm in length, 1800 mm in width, and 1416 mm in height, with a wheelbase of 2700 mm. Regarding configurations, the base model of the tenth-generation Civic is equipped with halogen headlights, while the higher-end models are upgraded to LED headlights and also feature a 360-degree panoramic camera system.

What Causes a Car to Shake and Stall?

The reasons for a car shaking and stalling are: 1. Throttle malfunction: such as a blocked throttle or carbon buildup in the throttle; 2. Excessive impurities in the intake tract, causing the onboard computer to be unable to precisely control the idle air intake; 3. Spark plug malfunction, such as electrode erosion or damage; 4. The use of low-quality gasoline leading to fuel pump blockage or insufficient combustion of the air-fuel mixture in the cylinder; 5. Issues with the fuel injector, such as carbon buildup or blockage. Solutions for a car shaking and stalling include: 1. Cleaning the fuel injector and refueling at reputable gas stations; 2. Cleaning the intake tract; 3. Cleaning the throttle.

What does an exclamation mark on the steering wheel mean?

An exclamation mark on the steering wheel is the warning light for the electric power steering system. If the indicator light stays on after the vehicle's ignition switch is turned on or during driving, it indicates a fault in the electric power steering system, and you should promptly go to a repair shop for inspection and repair. If the yellow indicator light is on, it means that part of the steering system has failed, resulting in increased steering effort and difficulty in turning. If the red indicator light is on, it indicates a complete failure of the steering system. The electric power system fault light may come on under the following circumstances: it lights up briefly for five to ten minutes and then turns off. This is because the electric power steering motor is overheated, and the system enters an overheating protection mode, reducing or pausing the motor assistance. The assistance will resume once the motor temperature decreases.

What Causes Vehicle Body Shaking While Driving?

Vehicle body shaking while driving can be caused by: 1. Low ignition energy. During startup, especially when the temperature of fuel and lubricating oil is low, more throttle is needed to meet power demands. Over time, the electrode gap of the spark plugs gradually increases, leading to a decrease in ignition energy and poor fuel atomization, which results in body shaking; 2. Aging ignition coils, high-voltage wires of spark plugs, or electrical leakage can also reduce ignition energy; 3. Abnormal engine coolant temperature, low cylinder pressure, or clogged fuel injectors. If the vehicle shakes upon startup, it is recommended that the owner promptly take it to a 4S shop for inspection and repair.
