What Causes the Steering Wheel to Make Noise at Low Speeds?

The causes of noise when turning the steering wheel at low speeds include the sound from the turn signal return mechanism, noise from the steering column dust cover, and noise from the shock absorber thrust bearing. Below are the specific reasons: Sound from the turn signal return mechanism: If the turn signal is activated while turning, the noise may come from the return clip of the automatic turn signal reset mechanism. The driver should confirm this. If it is indeed the case, this is a normal occurrence. Noise from the steering column dust cover: If the noise comes from below the steering wheel, it is likely caused by the steering column dust cover. Due to insufficient lubrication in the dust cover, friction noise may occur. In this case, applying some grease inside the dust cover will eliminate the noise. Noise from the shock absorber thrust bearing: If the noise originates outside the vehicle, it may be due to insufficient lubrication in the shock absorber thrust bearing. Open the hood and listen to determine if the noise comes from the top mount of the shock absorber. If so, the thrust bearing is the source. Applying grease to the thrust bearing may resolve the issue. If the noise persists, the thrust bearing will need replacement.

Which has louder tire noise, Giti or Goodyear?

Goodyear tires have louder noise. Goodyear tires are typical American products, with poor noise suppression performance. Their grip is second only to Pirelli, and the noise level is close to Pirelli. The advantages are wear resistance, harder tire composition leading to longer lifespan, and excellent grip and water drainage. The disadvantages are a tendency to pick up small stones and relatively high noise levels. Below are the performance characteristics of Goodyear tires and Giti tires: Goodyear Tire Features: Goodyear tires are relatively more wear-resistant, resulting in a harder tire body, along with strong grip and handling performance. They mainly focus on high-end tires, primarily equipping mid-range products of top-tier automotive brands, such as the BMW 5 Series, Mercedes-Benz E-Class, C-Class, etc. Giti Tire Performance: Giti tires emphasize wear resistance and long mileage, while also offering excellent comfort. Giti's global R&D team continuously pursues technological breakthroughs to enhance tire comfort, strengthen the rigidity of the central tread area, and mitigate and absorb vibrations caused by driving on complex road surfaces, ensuring a smooth and comfortable ride.

What are the models of Giti Comfort Silent tires?

Giti Comfort Silent tires come in two tread patterns: 228 and 221. Below are the introductions for these two tire tread patterns: Comfort 221: The Comfort 221 is a tire that balances comfort and handling, capable of improving wet road grip to ensure driving safety in wet conditions. It employs 3P Silent Balance Technology and a shoulder angle design combined with transverse auxiliary grooves to achieve noise reduction and sound absorption. Additionally, the seamless nylon cap ply enhances the tire's comfort and stability. Comfort 228: The Comfort 228 is Giti's top-tier comfort tire. Besides offering silent comfort, it also features long mileage and fuel efficiency. Similarly, it utilizes 3P technology and a multi-pitch chaotic tread pattern arrangement to effectively reduce road noise.

What does a car with a lock symbol on the dashboard indicate?

A car with a lock symbol on the dashboard represents the vehicle's engine immobilizer system. After locking the car, if the symbol does not flash, it indicates that the car is not properly locked or there is a malfunction in the anti-theft system. If it flashes, it means the anti-theft system is functioning normally. The immobilizer effectively prevents unauthorized engine starts, enhancing the vehicle's security. The functions of the car's anti-theft system include: Electronic anti-theft systems utilize signal transmitters and receivers to achieve theft prevention. These systems primarily consist of an electronically controlled remote or key, electronic control circuits, alarm devices, and actuators. The key contains a chip that amplifies its signal when near the ignition lock. The immobilizer's computer then verifies whether the key is authorized. If recognized, the engine can start; if not, ignition is blocked. By locking the ignition switch or preventing vehicle startup, the system achieves theft prevention. Once in "anti-theft" mode, an audible alarm is triggered. If issues arise with the system, visit a 4S dealership for repairs to prevent potential theft. For long-term vehicle storage, disconnecting the battery's negative terminal is an option, though this deactivates the anti-theft system. Alternatively, periodic driving helps maintain both the vehicle and battery health. Extended parking accelerates component aging. With technological advancements, modern vehicles universally feature electronic locks. A blinking red light when engaged is normal. These keyless systems eliminate external keyholes and include fuel cap protection, significantly reducing theft incidents. Electronic anti-theft system types include: key-controlled; remote-controlled; alarm-based; and combined immobilizer/movement prevention systems. During theft attempts, these may trigger alarms while simultaneously cutting starter, ignition, or fuel circuits to prevent vehicle movement.

Should the Right Turn Signal Be Used When Reversing for Parallel Parking?

When reversing for parallel parking, it is necessary to use the right turn signal. Below are the lighting requirements and precautions for parallel parking: Lighting Requirements for Parallel Parking: The lighting requirement for parallel parking is to use the right turn signal when reversing to the right and the left turn signal when exiting the parking space. Precautions for Parallel Parking: When driving to the test position, the vehicle body must not exceed the white line; do not delay entering the parking space too much, as waiting until the entire vehicle is inside the space may make adjustments impossible, directly causing the vehicle to press against the right line, which is the most common reason for crossing the line; when reversing into the space, control the speed appropriately—if the speed is too fast, there may not be enough time to straighten the vehicle, resulting in the rear wheels pressing against the rear line of the vehicle or the vehicle body touching the line; the driver should not only focus on adjusting the front of the vehicle but also pay attention to the distance between the right wheel and the edge line as seen in the right mirror. Additionally, turning the steering wheel too quickly may cause the right wheel to exit the space and press against the edge line.

How many points are deducted for the car body touching the edge line during parallel parking?

10 points are deducted for the car body touching the edge line during parallel parking. Below are the deduction criteria and techniques for parallel parking: Parallel parking deduction criteria: The task completion time must not exceed 90 seconds; exceeding the specified time results in disqualification; touching the parking space boundary line with the car body during movement deducts 10 points each time; failing to use or incorrectly using the turn signal when exiting the space deducts 10 points; stopping midway deducts 5 points each time. Parallel parking techniques: Ensure the car body is about 30 centimeters from the edge line of the parallel parking space and drive parallel past the space; move the vehicle forward, observe the right rearview mirror, and stop when the A corner of the space appears in the mirror; press the clutch, shift into reverse gear, and slowly back up; watch the right rearview mirror, and when the A corner disappears, turn the steering wheel fully to the right.
