What Causes the Loud Roaring Noise Inside the Buick Excelle When Driving?
2 Answers
The causes of abnormal noise inside the Buick Excelle while driving are loud engine noise and bearing burn-out leading to noise. Details are as follows: Loud Engine Noise: This is usually due to air leakage in the engine's intake pipe, improper installation of the air filter, or detachment of the vacuum hose. These issues can cause such noise during driving. A thorough inspection is required to ensure the intake pipe is reliably sealed, restoring normal operation. Timely maintenance is essential to ensure stable, comfortable, and safe driving. Bearing Burn-out Causing Noise: Drive the car up to 80KM, then shift to neutral and coast while listening carefully. If the noise becomes clearer, it can be determined that one of the four wheel bearings is faulty. If the noise disappears when coasting in neutral, it is generally due to a faulty bearing in the engine. Common engine bearing burn-outs usually involve the water pump, generator, or tensioner pulley.
I've been driving for many years and have encountered situations where the car makes a rumbling noise, usually related to the tires. Uneven wear or bulges can cause uneven surfaces on the tires, resulting in a low rumbling sound while driving, especially noticeable when the speed exceeds 60 km/h. It could also be due to aging or damaged wheel bearings, where insufficient lubrication causes friction noise. Last time my car had this issue, the sound from the faulty wheel bearing increased with speed and worsened when turning. For a quick self-check: when parked, manually rotate the tire to listen for unusual noises; if you feel hard lumps on the tire, it indicates bulging. However, it's best not to push it—drive to a repair shop for a professional inspection with proper equipment, and have the shock absorbers checked as well to prevent further damage to the chassis.
