What Causes the Abnormal Noise from the Left Rear Wheel of a Car?

Here are the specific reasons for the abnormal noise from the left rear wheel of a car: 1. Accumulation of foreign objects: Excessive accumulation of debris on the fender or sound insulation pad. When the car turns, the tire interferes with the debris, causing abnormal noise. After cleaning the fender, the tire noise disappears. 2. Loose screws: The fastening screws of the fender or sound insulation pad have come loose, causing the fender or sound insulation pad to lift. When the front wheel turns, it interferes with the lifted part, resulting in friction and abnormal noise. It is necessary to inspect the fastening condition of the fender and sound insulation pad and eliminate factors such as looseness and lifting. 3. Unauthorized modifications: Unauthorized modifications to the car tires, such as replacing them with non-original size tires. For example, widening the tires or increasing their diameter may cause interference between the tire and the car body when turning, resulting in noise. This poses a significant safety hazard, and the original size tires should be reinstalled.

What are the precautions for summer tires?

Precautions for summer tires include: 1. Regularly check tire pressure: Proper tire pressure is the primary condition for ensuring normal tire operation. Additionally, as temperatures are relatively high in summer, users can appropriately reduce tire pressure, which also serves as a good preventive measure. 2. Regularly replace tires: Many users continue to use expired tires to save costs, which is actually incorrect. Tires have a certain service life and usage cycle, and should be replaced regularly according to the specifications in the car maintenance manual. 3. Wear level: Some users have poor driving habits, which significantly increases tire wear. Once the wear exceeds a certain level, the tires need to be replaced promptly. For example, if the tread groove depth does not meet the standard, the tires should be replaced immediately.

Can car paint be sprayed directly on the original paint?

Car paint can be sprayed directly on the original paint. Below are the detailed steps for car painting: 1. Cleaning and sanding: After a collision or scratch, the metal panel usually needs to be repaired to its basic shape. Professional painting and sanding tools are used to remove the original paint, exposing the metal panel. 2. Filling dents: Applying putty ensures the paint surface is smooth and fills in any dents. This process typically needs to be done three times, as it affects the final painting result. 3. Base preparation: A paint scanner is used to match the car's paint color, followed by manual fine-tuning. Since different vehicles have varying ages, the paint may have slight variations, requiring the technician to compare the paint sample with the car's body color on-site. 4. Painting: The main types of paint used are standard paint, metallic paint, and pearl paint.

What causes the tire pressure light to come on?

The tire pressure light usually comes on due to either low tire pressure or high tire pressure, in which case tire inspection and pressure adjustment are necessary. Hazards of low tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Causes the steering wheel to feel heavy and makes the vehicle prone to drifting, among other factors detrimental to driving safety; Increases the movement of various parts of the tire, leading to excessive rolling and abnormal heat generation in the tire; Reduces the functionality of the cord and rubber, causing delamination or cord breakage and excessive friction with the rim, resulting in damage to the bead area and abnormal wear; Multiplies the friction between the tire and the ground, causing a sharp rise in tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to a tire blowout; Increases tire body deformation, making the tire side prone to cracking, while generating flexing motion that leads to excessive heat, accelerating rubber aging, fatigue of the cord layer, and cord breakage. It also increases the tire's contact area with the ground, accelerating wear on the tire shoulder.
