What Causes Abnormal Noise from Shock Absorbers?

2 Answers

Generally, when a car makes abnormal noises while driving on bumpy roads, it indicates that the shock absorber may be damaged. The specific possible reasons are as follows: 1. Damaged shock absorber: When the vehicle's shock absorber is damaged, the coordination between its components is compromised, causing a clunking noise during operation on bumpy roads. 2. Damaged shock absorber top mount: The front shock absorber top mount, made of rubber material, primarily assists the shock absorber and spring in providing cushioning and damping effects. When the top mount is damaged due to excessive wear, it not only produces noise during operation but also generates noise when turning the steering wheel while stationary, even if the shock absorber is not engaged.

I've been driving for so many years, and it's quite common to hear noises from the shock absorbers. I've encountered this issue several times. The reasons can vary—often, it's due to oil leakage in the shock absorbers, which reduces lubrication and increases internal friction, resulting in squeaking or clicking sounds. If internal components like springs or pistons are worn out, the damping effect weakens, causing a clunking noise when going over speed bumps or rough roads. Sometimes, it's just loose bolts, aging rubber bushings, or debris stuck in the gaps, all of which can cause unusual noises. This issue shouldn't be taken lightly, as it directly affects handling and ride comfort. On long drives, excessive bouncing can lead to uneven tire wear and increased fuel consumption. I recommend visiting a professional repair shop immediately to have a technician check if parts need replacement or tightening. During regular car washes, do a quick inspection around the tires for any oil stains—prevention is key for safety and peace of mind. Ignoring it could be dangerous; a friend of mine once faced a loss of control on the highway due to neglected shock absorber issues.

Can You Directly Add Oil When the Engine Is Low on Oil?

You can directly add oil when the engine is low on oil. Below are the relevant details: 1. The steps for adding oil are: (1) Open the engine hood. (2) Locate the oil filler port. (3) Add oil and check the oil level or for any leaks. 2. The functions of engine oil include: lubrication, auxiliary cooling, cleaning, sealing to prevent leaks, rust and corrosion prevention, shock absorption, and wear resistance. 3. The method for changing the oil is: (1) Lift the car, remove the protective plate, and place a container of about 10 liters under the oil drain plug. (2) Unscrew the oil drain plug, use an air gun to blow for two minutes at the oil filler port, and after draining, tighten the oil drain plug and wipe it with a paper towel to check for leaks. (3) Reinstall the protective plate and lower the car, then use a funnel to add oil through the filler port.

Does the Vehicle License Contain the VIN?

The vehicle license does contain the VIN (Vehicle Identification Number), which is a 17-character alphanumeric code serving as the car's unique identifier. This code can also be found in the engine compartment. Below is more information about the VIN: 1. The VIN, or Vehicle Identification Code, is a 17-digit alphanumeric combination that ensures no two vehicles of the same model are identical within 30 years, functioning as the car's unique ID, much like a human's ID card. 2. The last six digits of the VIN can be used to query detailed vehicle information. 3. The 17-character VIN is typically divided into six sections: Characters 1-3 represent the manufacturer, brand, and type; Characters 4-8 (or 4-9 in European standards) indicate vehicle characteristics. China follows the U.S. standard, using positions 4-8 for these features.

Can the negative terminal of a car be arbitrarily grounded?

Car negative terminal cannot be arbitrarily grounded. Function of grounding wire: It uses the iron parts of the car to conduct electricity, thereby saving a wire. Grounding means connecting one of the DC electrodes (positive or negative) to the iron body of the car, while the other electrode forms a circuit through the wiring and electrical equipment. This is the function of grounding. Grounding fault: Grounding fault is a term in circuit troubleshooting, commonly seen in the automotive repair industry. A grounding fault refers to the phenomenon in the electrical equipment circuit of a car where a non-grounded wire (or terminal) directly contacts the car frame, causing the power source to form a short circuit between positive and negative poles at this point. A minor grounding fault can cause car leakage, resulting in battery depletion, while a severe grounding fault can damage the power source (including the battery and generator), burn out the wiring, or even cause a fire.

Is There Any Harm in Putting Grapefruit Peel in the Car?

Putting grapefruit peel in the car is not harmful. Open the car windows more for ventilation: Before driving, choose a sunny day, open all the car doors, and let them air out for 2-3 hours while ventilating. Clean the interior and organize the items inside to keep it tidy and neat. Use charcoal or bamboo charcoal to remove odors: Activated carbon has rich capillaries and strong adsorption properties. When toxic gases come into contact with activated carbon, they are adsorbed onto the capillaries, purifying the air. It doesn’t take up much space and is harmless, providing clean air in the car for a long time. Regularly clean the air conditioner: Due to seasonal changes and environmental factors, air conditioners can easily breed bacteria and viruses. If not cleaned regularly and the air filter is not replaced in time, they may release toxic or germ-laden gases. Inhaling these can lead to illnesses. Car air purifiers: Currently, technologies mainly include plasma, negative ions, negative oxygen ions, and adsorption. The higher the clean air delivery rate, the more efficient the purifier is.

How to Turn Off the Daytime Running Lights on a Bora?

Here are the steps to turn off the daytime running lights on a Bora: 1. Insert the car key and turn it to the position where only the radio can be used. Pull the switch on the left side of the combination switch towards the driver's direction and simultaneously pull it downwards. Hold it in this position without releasing. 2. Turn on the car key. After about 3 seconds, you will hear a "dong" sound, indicating that the operation was successful. The functions of daytime running lights are as follows: 1. Daytime running lights are designed to make the vehicle more noticeable during daytime driving. Their purpose is not to help the driver see the road better but to inform others that a vehicle is approaching. Therefore, these lights are not for illumination but serve as signal lights. 2. While adding daytime running lights can make a car look cooler and more stylish, their primary benefit lies not in aesthetics but in enhancing the vehicle's visibility. Studies abroad have shown that using daytime running lights can reduce vehicle accidents by 12.4% and lower the fatality rate in car crashes by 26.4%.

What is the displacement of the Passat 330tsi?

The SAIC Volkswagen Passat 330tsi has a 2.0T displacement. Displacement refers to the volume of fluid inhaled or expelled per stroke or cycle. Volkswagen initially used TSI to indicate engine displacement, where T stands for turbocharged engine, and SI represents the direct fuel injection method. If only the I in the car's rear badge is red, it indicates the car's engine has a 1.4T displacement. The Passat 330tsi is equipped with a 2.0T turbocharged engine, with a maximum horsepower of 186ps, a maximum torque of 320nm, and a maximum power of 137kw. It is paired with a 7-speed automatic transmission. Generally, the model designation represents the engine displacement. The 280, 330, and 380 models each represent different displacements to better reflect the car's engine size. The 280 base configuration comes with a 1.4T engine, available in both high and low power versions, while the 380 base configuration features a 2.0 engine with the highest power. However, the low-power version would be the Passat 330's 2.0T engine, still maintaining a 2.0T displacement. These designations are common for this model series, effectively indicating the engine's displacement.
