The reason for the squeaking noise from the suspension when starting a Volkswagen CC is due to damage, deformation, or detachment of the brake shoe support plate, damping spring plate, or guide plate of the disc brake. This causes an increase in the clearance between the brake shoe and the brake caliper support frame in all directions, leading to mutual impact and resulting in the noise. Introduction to the automotive suspension system: The automotive suspension system refers to the entire support system composed of springs and shock absorbers between the body and the tires. The functions of the suspension system include supporting the body and improving ride comfort. Different suspension setups provide drivers with varying driving experiences. Although seemingly simple in appearance, the suspension system integrates multiple forces and determines the stability, comfort, and safety of the vehicle, making it one of the most critical components in modern cars. Functions of the suspension system: The suspension system is the general term for all force-transmitting connection devices between the car's frame and the axle or wheels. Its role is to transmit forces and torques acting between the wheels and the frame, while also cushioning the impact from uneven road surfaces transmitted to the frame or body and dampening the resulting vibrations to ensure smooth driving.

When I drive my Volkswagen CC, the suspension always creaks and squeaks when starting off. At first, I thought it was a brake pad issue, but the noise occurs at low-speed turns and disappears at high speed. After analysis, it might be due to aging rubber bushings in the suspension system. Volkswagen cars tend to develop hardened and cracked rubber after a few years, especially the buffer components near the control arms or shock absorbers that wear out or lack lubrication. The weight transfer during acceleration causes these parts to rub. Another possibility is dust or debris stuck in the spring seat, causing scraping noises. I recommend not delaying—this noise indicates worsening parts. If the bushings fail completely, it could affect steering stability. I plan to visit the 4S store this weekend and have the technician lift the chassis for inspection. Probably just replacing a small part will fix it, costing a few hundred bucks. Peace of mind while driving is what matters most.

What is the appropriate tire pressure for the Arrizo 5?

The normal tire pressure range for the Arrizo 5 is 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2 bar in winter and reduced by 0.1 bar in summer. This data is based on the requirements and regulations of the international GBT2978-2008 standard. If you want to check the current tire pressure of the Arrizo 5 during daily driving, you can activate the tire pressure monitoring system, and the tire pressure value will be displayed on the central LCD screen of the instrument panel. The specific method is to press the LCD adjustment button on the combination instrument panel on the left side of the steering wheel and switch to the tire pressure monitoring system interface. Generally speaking, a tire pressure exceeding 2.8 bar is considered too high, while a tire pressure below 2.0 bar is considered too low. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; causing steering wheel vibration and deviation, reducing driving comfort; accelerating localized wear of the tread center pattern, shortening tire lifespan; increased vehicle vibration, indirectly affecting the lifespan of other components; excessive stretching deformation of tire cords, reduced tire elasticity, and increased load during driving. Hazards of underinflated tires: Increased friction coefficient with the road surface, leading to higher fuel consumption; heavy steering wheel and other factors detrimental to driving safety; increased movement of tire parts, causing abnormal heat due to excessive rolling; reduced functionality of cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, causing damage to the bead area and abnormal wear; multiplied friction between the tire and the ground, rapid rise in tire temperature, softening of the tire, and sharp decline in strength. High-speed driving may result in tire blowouts. If the tire pressure monitoring indicator light comes on (a yellow symbol with an irregular circle, no seal on top, four small spikes at the bottom, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: Usually, an alarm is triggered when the pressure is below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the system will still record the previous data, causing the tire pressure monitoring indicator light to come on. Simply perform a tire pressure reset in this case. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is directly installed inside the tire and connected to the tire inflation valve. If the sensor is damaged due to impact while driving, the tire pressure fault light will also illuminate. For sensor damage issues, only a complete replacement of the component is possible.

What are the reasons for the oil pump not pumping oil?

The oil pump may fail to pump oil due to reasons such as low oil level, excessively low oil temperature, insufficient suction force of the oil pump, or blockage in the suction pipe. Below are the detailed reasons why an oil pump may not pump oil: Low oil level: If the oil level is too low, it exposes the suction pipe. When the oil level is too low, the suction pipe of the oil pump is exposed above the oil surface, making it impossible to draw oil even with strong suction. It could also be due to the suction pipe being positioned too high, preventing the oil pump from drawing oil. Immediate action is required: add engine oil, stop driving, turn off the engine, park the vehicle on a flat surface, wait for about ten minutes, open the oil filler cap, and add the same type of oil as originally used until the oil level reaches the midpoint between the upper and lower marks on the dipstick, then stop adding. Excessively low oil temperature: When the oil temperature is too low, the viscosity of the oil decreases. Under normal temperatures, oil exists in a semi-solid state, but as the temperature drops, it becomes more solid. This makes it difficult for the oil pump to draw oil, which is why the oil pump fails to pump oil. It is important to inspect related components promptly and resolve the issue quickly to prevent minor problems from escalating into major failures. Insufficient suction force of the oil pump: If the suction force of the oil pump is not strong enough, it cannot effectively draw oil from a lower level to a higher one. The oil pump relies on strong suction to draw oil through the suction pipe. If the suction force is inadequate, the oil cannot be pumped efficiently. It is recommended to check the voltage of the fuel pump. For imported or joint-venture compact cars, the oil pump may not be repairable and might need replacement. Blockage in the suction pipe: A blockage in the suction pipe can prevent the oil pump from drawing oil. The smooth operation of the suction pipe is essential for the oil pump to function properly. If the suction pipe is obstructed by foreign objects, the oil pump will fail to pump oil. Inspect the suction pipe and remove any obstructions.

What is the ground clearance of the Mazda3 Axela?

The ground clearance of the Mazda3 Axela is 150mm when unloaded and 125mm when fully loaded. The size of the ground clearance determines the vehicle's ability to pass over obstacles or uneven terrain. More information about the minimum ground clearance of a car is as follows: 1. The minimum ground clearance of a car refers to the distance between the lowest point of the car (excluding the wheels) and the ground when the car is unloaded or fully loaded. It indicates the car's ability to pass over obstacles like stones without collision. 2. Generally, sedan models have relatively small ground clearance because they are usually driven on flat urban roads. Off-road vehicle models have larger minimum ground clearance, allowing them to better overcome larger obstacles.

What Are the Causes of Front Wheel Abnormal Noise?

Car front wheel abnormal noise can be caused by the following reasons: 1. If there is a rhythmic sharp noise, it is the friction sound caused by the brake pads being too close to the brake disc. 2. A continuous sharp noise indicates bearing damage. 3. A continuous dull noise suggests a problem with the drive shaft. Car tires are one of the important components of a vehicle, directly in contact with the road surface, working together with the car suspension to mitigate the impact during driving. Car tires ensure good ride comfort and smooth driving; guarantee excellent adhesion between the wheels and the road surface; improve the vehicle's traction, braking, and passing performance; and bear the weight of the car.
