What Causes the Abnormal Noises in Lexus Vehicles?
1 Answers
Lexus vehicle abnormal noises are caused by loose suspension, brake system malfunctions, slack engine belts, and aging rubber components. The specific reasons are as follows: Loose Suspension: If abnormal noises occur during slow driving, it is likely due to a loose suspension. The vehicle's suspension includes links, springs, shock absorbers, and stabilizer bars. Any abnormality in one of these components, such as loose bolts, can cause noise due to shaking. The solution is to promptly inspect the suspension for looseness and tighten any loose parts. Brake System Malfunction: If the abnormal noise increases when applying the brakes, it is definitely a brake system issue. Problems such as excessively thin brake pads, uneven wear between the brake disc and brake pads, or faults in the brake calipers, master cylinder, or wheel cylinders can all lead to abnormal noises in the brake system, typically manifesting as sharp and continuous sounds. The recommended solution is to promptly visit a repair shop for inspection and replacement of parts if necessary. Slack Engine Belt: A slack engine belt can produce abnormal noises. The solution is to try pinching the drive belt with your fingers and twisting it, ensuring the operation is performed with the engine cooled down. The twist angle should generally be below 90 degrees; otherwise, the belt tension needs adjustment. Aging Rubber Components: Aging of components typically occurs in areas with rubber parts, particularly the engine mount cushions. If these harden or crack due to aging, it can lead to increased vehicle vibration, steering wheel shaking, and louder noises. The solution is to regularly inspect rubber components and replace any aging parts promptly.
