Many car owners have had the frustrating experience of hearing their vehicle make an unusual noise, only to be stumped when trying to diagnose what’s causing it. Fortunately, there are some common causes of strange car sounds that can easily be identified; for instance, if you hear creaking while driving, that could indicate worn-out wheel bearings.
Wheel bearings are essential elements in a car’s suspension system, allowing the wheels to rotate freely while supporting the weight of the vehicle.
A typical wheel bearing
consists of an inner and outer race with rolling elements (either balls or cylinders) in between. These reduce friction while keeping your bearings rotating smoothly.
Over time, however, wheel bearings can become worn down, leading to increased friction and decreased performance. Furthermore, worn wheel bearings generate heat which could damage other components of the suspension system.
The bearings are what allow the wheels to rotate smoothly, and they take a lot of abuse over the course of a car’s lifespan. Eventually, these bearings may wear down, leading to creaking noises when driving slowly along with feelings of vibration as well.
If you observe any of these symptoms, it’s imperative that your bearings get checked out by a mechanic immediately. Although bearings are relatively inexpensive to replace, leaving them unchecked could eventually result in more serious damage.
2. Worn-out brake rotors

If your car is making a creaking noise while driving, it could be due to worn-out brake rotors. Rotors are circular discs that brake pads grip onto and slow down wheels; over time these can become worn down and develop ridges or grooves which cause brake pads to make noise as they try to grip onto the uneven surface of the rotor.
Brake rotors are an integral part of any vehicle’s braking system. These metal discs rotate along with the wheels, providing a surface for brake pads to grip onto, slowing down your car.
Unfortunately, brake rotors can wear out due to repeated use or exposure to elements, so they may need replacement at certain intervals.
Neglecting this issue will eventually lead to complete wear-and-tear on your brake rotor, and eventually, they won’t function at all. Fortunately, replacing worn-out brake rotors is a relatively straightforward process that can be completed within several hours.
When shopping for brake rotors, it is essential to select a trusted brand with an excellent warranty. Installation is usually straightforward but consulting with a professional mechanic for proper setup is recommended.
3. Bad calipers
If your car is making a creaking noise when driving slowly, it could be due to malfunctioning calipers. When these fail, they often become stuck in a semi-closed position where they apply pressure on the brake rotors as if you were constantly braking. This is especially noticeable when going slowly; you can hear the clicking noise caused by constant contact between calipers and discs.
Car calipers are an essential element of a vehicle’s braking system, pressing brake pads against rotors to create friction that allows your car to stop. Most cars have four calipers – one at each wheel – mounted on either side of the rotor and connected to your pedal through hydraulics.
When the brake pedal is depressed, hydraulic fluid is sent to the calipers, forcing them to close. This applies pressure on brake pads which in turn apply pressure to rotors – slowing down wheel rotation and bringing your car to a complete halt. Although calipers are made to last for years, they can become worn or damaged over time.
In addition to making noise, malfunctioning calipers can also lead to brake problems or failure. Therefore, it’s essential that you have them checked by a qualified mechanic as soon as possible. With proper care and maintenance, your car will run smoothly for years to come.
4. Loose accessory belt

Have you ever noticed a grinding noise coming from your car engine when driving slowly? That could be an accessory belt. This small, relatively thin belt drives several engine components such as the alternator, power steering pump, and water pump. Most cars only have one accessory belt but larger vehicles may have multiple ones.
The accessory belt is a serpentine belt that drives various components on most vehicles, including the alternator, water pump, power steering pump, and air conditioning compressor. It usually runs at the front of the engine and is driven by either the crankshaft or camshaft in some models. Regular checks of this belt for wear and tension should be conducted to ensure optimal performance.
Regularly checking the condition of your accessory belts is an essential part of preventative maintenance. Fortunately, it’s simple to check for a loose belt: start the engine and listen for any squealing noises; if you hear one of them squealing, it could indicate that one is loose.
Next, open the hood and visually inspect all belts for any signs of fraying or wear. If you notice any damage, replace the belt as soon as possible. By taking these simple steps, you can help guarantee that your car’s engine stays in excellent working order.
5. Loose timing chain
If your car starts making a creaking noise when driven slowly, it could be due to an issue with its timing chain. While this problem is most commonly found in older models, it can affect any vehicle.
Timing chains are essential elements in the engine of a car, keeping its crankshaft and camshafts aligned so pistons and valves can move together in perfect harmony. The timing chains reside inside the engine, connecting the crankshaft to its camshaft (or camshafts).
Timing chain: an essential part of an engine, it should be replaced at regular intervals. Timing chain: composed of gears that rotate camshaft and crankshaft in sync.
Timing chains are essential in engines; they ensure all moving parts within the engine work in sync with one another. If one were to break or become damaged, this would cause the engine to seize up and cease operation completely.
Timing chains on most car engines eventually need replacing, depending on the make and model of a vehicle. On average, timing chains last anywhere from 60,000-150,000 miles depending on usage; however, it’s common for them to need replacement earlier if not properly maintained.
6. Failing transmission
A car transmission is a system of gears that helps propel the wheels of a vehicle. It connects to the engine and uses pulleys and belts to transfer power onto the wheels. There are two primary types of transmission: automatic and manual.
Automatic transmissions rely on sensors to determine when to shift gears, while manual transmissions require the driver to operate a clutch and shifter manually. Each type of transmission has its own advantages and drawbacks, but both are essential for making your car run efficiently.
Cars are built to last, but that doesn’t mean they don’t require some regular upkeep. Over time, parts can corrode or break, and fluids leak. When your transmission starts malfunctioning, you may hear all sorts of odd noises like creaking, grinding, and humming while driving slowly.
If your car is making any of these sounds, it’s essential that you get it checked out by a mechanic right away. A malfunctioning transmission is an urgent problem that could cause extensive damage if not addressed quickly.
7. Bad CV joint
![Car Making Creaking Noise When Driving Slow [8 Possible Causes]](https://www.carcarehacks.com/wp-content/uploads/2022/11/Car-Making-Creaking-Noise-When-Driving-Slow-8-Possible-Causes-7-1024x768.jpg)
The CV joint in a car helps transfer power from the engine to the wheels. Located at the end of the drive shaft and connected to the wheel hub, this joint allows the drive shaft to rotate while leaving the wheels stationary – an essential feature when turning.
Furthermore, this part is protected with a rubber boot that shields it from dirt and debris.
The CV joint is responsible for connecting the axle to the wheels, allowing them to pivot freely as the car turns. As it wears down over time, it may begin making a creaking noise or be damaged if your car hits a pothole or bump.
If you believe your car’s creaking noise is due to a failing CV joint, make sure it gets checked out by an experienced mechanic promptly. Otherwise, you could end up stuck on the side of the road with no way of getting help.
8. Worn suspension bushings
The suspension system on a car is responsible for providing a smooth ride. It consists of various components, such as shocks, struts, and springs. Another essential part is bushings made out of rubber or polyurethane that act as cushions between moving parts within the suspension.
Are you hearing creaking noises coming from your car while driving? It could be the suspension bushings. These rubber components help dampen vibrations and protect the suspension system of your car against wear and tear. However, over time they may become worn out and brittle, leading to creaks or squeaks while in motion.
When replacing suspension bushings on your car, it is essential to choose the correct type. Otherwise, you could end up with an uncomfortable ride.
Most auto parts stores can help you select the ideal bushing type for your vehicle; with just a bit of research, you can ensure your car has optimal suspension performance.
