What are the symptoms of a broken steering gear in a large truck?

The following are the symptoms of a damaged steering gear in a large truck: 1. Oil leakage from the steering gear. 2. Abnormal noise when turning the steering wheel. 3. A 'click' sound when turning the wheel to the extreme and returning. 4. Heavy steering wheel. Below are the causes and solutions for steering gear malfunctions: 1. Power steering pump failure. When the pump pressure of the power steering pump fails to meet the standard value, it is evident that the heavy steering is related to this. Check whether the mating surface of the flow control valve and the valve seat is not tightly sealed, and whether the safety valve steel ball is not properly closed. 2. Steering gear failure. If the inspection reveals that the hydraulic pressure of the steering gear is low, it indicates that the heavy steering is caused by the steering gear. In this case, professional manufacturers should be consulted for repair. Most steering gear failures are caused by scratches on the piston or cylinder barrel, or damage to the piston seal ring, which allows the two chambers of the piston to communicate, preventing the effective establishment of assist pressure. 3. Lack of oil or air in the system. If the power steering system lacks oil, causing air to enter the system, not only will the steering feel heavy, but there will also be noise during steering. In this case, simply follow the oil filling and air bleeding procedure to remove the air.

How to Adjust Electric Rearview Mirrors?

In the electric rearview mirror adjustment knob, L represents the left rearview mirror, and R represents the right rearview mirror. The following are the steps to adjust electric rearview mirrors: 1. The driver sits in the driver's seat and locates the electric adjustment knob on the left door. 2. Observe the white dot on the adjustment knob and the letters beside it. To adjust the angle of the left rearview mirror, rotate the knob's white dot to the L position. (To adjust the right rearview mirror, rotate it to the R position). 3. Then lift the knob upward to change the mirror's viewing angle upward. Similarly, pressing the knob downward changes the viewing angle downward. For left and right adjustments, use the same method of tilting the knob. Below is additional information on electric rearview mirror adjustment: 1. When adjusting the viewing angle of electrically adjustable rearview mirrors, it can be done via the electric buttons inside the car. 2. The buttons are generally designed on the left side of the steering wheel and can adjust both left and right rearview mirrors. When driving on narrow roads, the mirrors can be folded to improve the car's maneuverability.

How to Push-Start a Manual Transmission Car?

Below are the steps for push-starting a manual transmission car: 1. Before pushing, turn the key to the ON position to power up the vehicle without manually cranking the ignition. 2. Then depress the clutch pedal and shift into second or third gear. 3. When the pushing speed reaches about 10km/h, release the clutch while gently applying throttle. 4. Once the engine shows signs of starting with operational sounds, quickly depress the clutch, shift to neutral, and control the throttle properly to complete the startup. Precautions for push-starting a manual transmission car: 1. This method is typically used when the battery has insufficient charge due to circuit shorts during driving or damaged wiring, making it unable to restart after stopping. Push-starting is the simplest and most convenient solution but requires certain conditions; use this method if circumstances permit. 2. Pushers must ensure safety—the vehicle should be on flat ground with adequate speed distance, and the pushed vehicle must have functional brakes. 3. Applicable scenarios: When the vehicle lacks power or has insufficient power.

What Causes Continuous White Smoke from Car Exhaust in Winter?

White smoke from car exhaust in winter is actually water vapor adhering to the inner walls of the muffler. Here are the reasons for continuous white smoke from car exhaust in winter: 1. The exhaust gases exiting the tailpipe are at a relatively high temperature. 2. The high-temperature water vapor rapidly cools when ejected from the tailpipe, quickly condensing into visible white smoke or small water droplets. Below is additional information about car exhaust: 1. Car exhaust poses significant hazards, with main pollutants including carbon monoxide, nitrogen oxides, hydrocarbons, lead, sulfides, etc. 2. Harmful substances emitted during vehicle operation damage both the environment and human health: The environmental pollution caused by car exhaust mainly manifests as contributing to the greenhouse effect, ozone layer depletion, and phenomena like acid rain and black rain. 3. The harm to human health primarily includes causing various diseases, severely damaging the respiratory system, and exhibiting strong carcinogenic properties.

Does ETC need to be connected to a power source?

Installing ETC does not require an external power connection as it uses its own built-in power source. The ETC electronic tag consumes power, but it does not need to be charged during normal use because there is a solar panel on the back of the battery that can charge it automatically. During installation, it is necessary to avoid the black areas on the windshield. The built-in power source of ETC typically has a lifespan of 3-5 years. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply for ETC, you need to provide the original and photocopy of the vehicle owner's valid ID card and vehicle registration certificate. If the application is not made by the owner, the agent's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. Additionally, a bank card for deducting highway tolls is needed. Applicants must be between 18 and 60 years old, and the vehicle must be registered under an individual's name. For company vehicles, the required documents include: An introduction letter from the vehicle owner (with official seal); photocopy of the organization code certificate or business license (with official seal); original ID card of the agent; original vehicle registration certificate; and the vehicle that needs to be equipped with ETC. How ETC works: The onboard electronic tag installed on the vehicle's windshield communicates with the microwave antenna in the ETC lane at the toll station. Using computer networking technology, it settles the toll with the bank in the background, allowing the vehicle to pass through highway or bridge toll stations without stopping to pay. Benefits of installing ETC: Time-saving: Avoid the hassle of waiting in line; Green and eco-friendly: Low-carbon solution, as vehicles pass through toll stations without stopping, reducing noise and exhaust emissions; Cost-saving: Reduces vehicle start-up and braking frequency, minimizing wear and fuel consumption. Users can also enjoy toll discounts; Efficiency improvement: ETC lanes can theoretically increase passing efficiency by 2-3 times, making traditional ETC more updated, faster, and higher-tech. Compared to license plate payment, ETC technology is more mature and advantageous.

What Causes Car Brake Noise?

Here are the reasons for car brake noise: 1. During brake disc break-in period; 2. Normal activation of ABS system; 3. Foreign objects between brake pads and discs; 4. Rust on brake disc surface; 5. Excessive wear of brake pads or discs; 6. Assembly issues; 7. Problems with new brake pads. Below is extended information about car brakes: 1. The braking system consists of control system, hydraulic system and booster system. The brake device generates friction between the brake pads and wheel drum or disc, converting the kinetic energy during car movement into heat energy during the friction process. 2. The principle of braking system is to create enormous friction that converts vehicle's kinetic energy into heat energy.
