What Causes the Gurgling Sound When Driving at Low Speed?
3 Answers
The reason for the gurgling sound when driving at low speed is an issue with the engine chassis. This sound usually indicates wear and gap in the suspension links, and it is recommended to visit a nearby repair shop for confirmation and replacement. The chassis refers to the part of the car composed of the transmission system, running system, steering system, and braking system. It supports and installs the car engine and its various components and assemblies to form the overall shape of the car, bears the engine power, and ensures normal driving. Chassis maintenance should be highly valued as it directly affects the car's safety, handling, comfort, economy, and other key performance aspects. It is recommended to regularly maintain the chassis at a professional repair shop.
I've experienced this issue a few times, a gurgling sound at low speeds, most commonly it's a problem with the braking system, such as worn brake pads or foreign objects stuck in them. Sometimes it's suspension components like a broken shock absorber causing the sound from the car's vibrations. I suggest you first park the car in a safe place, get out and check if there are any stones or debris in the tires, and listen to whether the sound is coming from the front or the back. If the sound is from the front, it might be related to the brakes; if it's from the back, it could be related to the chassis or bearings. Don't underestimate it, as the sound getting louder could affect braking performance and increase the risk of an accident. Quickly go to a nearby repair shop and have a mechanic check it with tools, don't tough it out on your own. Usually, pay attention to road conditions while driving, avoid gravel roads, and regular car maintenance can reduce such troubles.
As a frequent driver, the low-speed rumbling noise often worries me. It could be an issue with the wheel bearings—aging or water ingress can cause noise. There's also a possibility of suspension system failure, such as looseness at the lower control arm connection. I remember when my car had this problem, the inspection revealed a damaged suspension bushing. First, ensure safety by stopping the car and gently shaking the wheel to listen for any abnormal sounds. If there's noticeable shaking, the bearings likely need replacement. During routine maintenance, pay attention to lubricating the chassis components to prevent dust buildup. Additionally, the noise is more noticeable on rainy days, so it's good to wash the chassis more often after driving in the rain. These small habits can extend the car's lifespan and ensure the safety of family trips.
