Why does the car make a creaking sound at low speeds but disappears when accelerating?

If a "squeaking" sound occurs when braking, it is mostly caused by excessive wear of the brake pads or the formation of unwanted gaps. The following are specific reasons: Excessive wear of brake pads: Under normal preload conditions of the main reducer bearings, if a metal impact sound occurs at the rear axle shortly after starting the car or during gear shifting, and the impact sound turns into continuous noise when the speed stabilizes, or if irregular "clicking" sounds occur at the rear axle when the throttle changes abruptly, this is generally due to excessive backlash. If the car produces a "howling" sound at low speeds, similar to a fire truck siren, and "clanging" sounds during acceleration or deceleration, accompanied by rear axle overheating, this is usually caused by insufficient backlash. These are the reasons for the aforementioned abnormal noises. Formation of gaps in brake pads: If there is an uneven backlash in the gear teeth, a rhythmic "grinding" sound may occur when starting the car or during sudden speed changes. Additionally, when turning, the rear of the car may shake, which is typically caused by uneven backlash.

I'm someone who enjoys tinkering with cars. The creaking sound at low speeds that disappears when accelerating sounds like a suspension system issue. Those worn-out or deformed rubber bushings on the shock absorbers or control arms create friction noise during low-speed turns or when going over bumps. At higher speeds, the vibration frequency increases, making the noise less noticeable. Loose brake discs or wheel hub bearings can also cause similar sounds, especially during acceleration and deceleration. Unfastened chassis bolts may produce this issue too. I recommend checking the suspension components over the weekend to look for obvious wear or gaps. Parking away from potholes in daily use can reduce wear. If the problem persists, take it to a shop for a comprehensive chassis inspection to avoid minor issues turning into costly repairs. Safety first—don't risk accidents while driving.

As a veteran driver with ten years of experience, I can tell you this phenomenon is quite common, mostly due to issues with the chassis or drivetrain. A creaking sound at low speeds that disappears when accelerating could be caused by aging suspension bushings, loose brake pads, or damaged wheel bearings. The reason is that components resonate and rub at low speeds, becoming less noticeable at higher speeds. I once encountered this during a long trip, and later inspection revealed cracked shock absorber bushings. It's important to drive slowly on uneven roads to reduce impact. If the noise gets progressively louder, don't hesitate—take it to a proper repair shop for inspection. Check the suspension, brakes, and bearings; usually, replacing a part for a few dozen dollars will fix it. This isn't a major issue, but ignoring it can lead to accidents and compromise driving safety.

Young car owners, let's talk about this issue. If there's a creaking sound at low speeds but not during acceleration, it's usually due to something loose or worn out under the car's chassis. This is common in suspension components like shock absorber bushings or control arms, where friction causes noise at low speeds but disappears at high speeds. The braking system could also be the culprit, such as loose disc brake pads scraping during low-speed movement. You can do a simple check yourself for any loose parts around the wheels or chassis, but if you're unsure, don't tamper with it. Head to the repair shop as soon as possible—replacing a part is usually not expensive. Paying more attention to these components during maintenance can extend their lifespan. Keeping safe driving practices is key.
