What Causes and Solutions for Grinding Noise When Turning?

Are you aware that your car can speak? Cars have their own language, and just like a baby who cries to tell you the diaper needs changing, a car gives plenty of signals whenever there is something wrong inside its large body. One noticeable type of signal is strange noises, such as grinding noise when turning the steering wheel.

In fact, the steering wheel can produce as many as 10 kinds of weird noises, each pointing to a different problem in itself or elsewhere. Fortunately, this problem can be easily dealt with. Read on to find out what your car is trying to tell you and how to bring it back to its top condition. 

How to Diagnose a Car’s Problem

You will notice that mechanics diagnose a problem by merely listening to the noise. The best way is to check the car’s condition when humming into first-second and third gears. To identify the cause of the problem at first, you need to recognize the source. Furthermore, when you turn and hear the sound, gauge whether it is coming from the rear or the front side.

Probable Causes of Grinding Noise When Turning

After consulting several mechanic experts about the key reasons behind grinding noise in a car, you will notice that every car model has its unique problem. Considering that every car model is unique and so is the problem, it is difficult to guarantee the absolute cause in the car.

But, here is the list of top three most likely causes for grinding noises.

Have a look!

1. Poor Wheel Bearings

If you are driving your car and it makes a noise when turning and it sounds like grinding, poor wheel bearings can be the cause behind it. Bearings act like a buffer between an axle and the wheel. Due to this, they prevent friction between the two moving parts. Therefore, the worn out wheel bearings lead to friction that causes the grinding sound when turning as the car bends.

The same noise persists when the car accelerates. So, the way out to stop the noise is simple – change the bearings.

2. Problems Related to CV Joint

It’s a less known fact that problems in the CV joint may cause the grinding noise when turning. CV joint is a part of the drive shaft, which comes acts a key role when turning. The problem in the CV joint can be major or minor, but all you need is to check out the axle to find out the issue.

3. Issue in the Brakes

Another important source of the weird noise can be a problem with the brake assembly. The key issues are a loose brake shield, worn out brake caliper and pads, or rotor misalignment. In any case, the best way is to check the entire brake system.

Noise from any part indicates friction that rips any car apart. Hence, it is essential to figure out the issue as soon as possible.

10 Grinding Noise Types When Turning

1. Sounds like wind whistling

When you start the car and hear the sound of the wind blowing from the engine, it is possible that the engine’s cooling system or the vacuum tube of the engine is leaking. This phenomenon can cause the engine to overheat and make the car more fuel consumption.

2. Sounds like a metal collision

When you drive and do not have any collisions, the car does not go through the pits but hear the sound like the collision of the metal plate together, it means, some parts the car is in trouble. This may be due to the deterioration of the joints, the wear and tear of the steering wheel, or the problems of the chassis or suspension system. In addition, the liquid outlet is also one of the causes of this noise.

3. Sounds like animals scream

For a normal day and you get the car to work and when you start up, you suddenly hear the “frightening” sound like some animals called when punctured, it could be due to rubber strap worn out or not also ensure the tension. The cost to “turn off” this noise of the engine is quite cheap so you do not hesitate to bring the car out to repair.

4. Sounds like hissing or moaning from the throat

This is a sign of the problem happens with brake system of the car. There are many types of brakes made up of small metal plates rubbed into the rotor. When the metal plates wear out to a certain degree, the friction of the brake system on the rotor cause the strange sound.

5. Repeat noises

Is your car equipped with a front-wheel-drive system and when traveling at slow speed, it emits a repetitive rattle? This is a warning sign of problems occurring in the coupling of the transmission. If the sound comes from the rear of the car, it may be because the rear of the car is having problems.

6. Sounds like a growl or moan

If the car sounds like a lion roars, it is very likely that the power steering is having problems. New models, including trucks and cars, are equipped with steering wheel electric power to replace the hydraulic auxiliary system as before. However, after only a few years of use, this power system begins to show signs of recession. When it detects these sounds, it is best to take your car for maintenance, if it is last too long, it will be difficult to turn the steering wheel, and cause danger.

7. Sounds like the hammer knocked out under the car’s head

This is a sign that the ignition system is experiencing abnormalities, possibly early ignition. This phenomenon usually occurs when you accelerate or start the engine startup. It is very harmful because it can damage the piston system. To overcome this, you can use higher octane gasoline, which helps to delay the ignition timing and the non-carbonation process in the combustion chamber.

8. Sounds like a knock on the door

When the engine emits a “coke” like a door knock, it may be a system to raise fuel pumps that can’t push fuel or pump valves that have gaps that need to be adjusted.

9. The crunching sound comes from the gearbox

Is your vehicle equipped with a gearbox, when starting to sound crunching while the gearbox is still active? It can be a sign of many different problems: it may be because the clutch is in trouble.

10. Sounds like baby crying

If your car uses a rear-wheel-drive system and emits this sound from behind when you are accelerating or decelerating, then the gears worn or the bearings are damaged.

Solutions for Grinding Noise When Turning

1. The method of preventing noise at the source

The method of preventing noise at the source is the first solution for grinding noise when turning, it consists of isolating it before entering the cabin and reducing the frequency of oscillation. Sound insulation at the source is said to be the most effective method. However, it is not always possible. For example, the tires are uncomfortable when riding on rugged roads. The different tires will have different noise levels. So, the same car, but the tire is louder than the tire. Almost all manufacturers provide noise on their tires.

2. Use of soundproofing materials

This method is also known as noise isolation and is performed mainly on metal parts. If the car makes grinding noise when turning, you should use this method. The rubber between the suspension and the body of the car can prevent noise. The plastic between the two metal parts also performs a sound reduction function. Operators often use this method to oscillate the engine without entering the cabin. Adding sponges to the metal shaft not only increases structural strength and prevents the material from vibrating.

The metal plate on the body is attenuated by attaching the ma-tiz or the flexible soundproofing panels inside. To optimize soundproofing, Ford engineers use a large set of built-in speakers. They turn the volume at different levels. When the tire vibrates, a laser scanner determines which position vibrates the most. Engineers only need to add sound insulation material to the area.

The use of sound insulation is simple, but the weight of the car increased, increasing fuel consumption. So, how much to add should be carefully calculated, to achieve both requirements in the best way.

3. Change the negative frequency

Negative frequency change is the third way that carriers use, especially for cabinets. Human ears often do not hear sounds that are too high or too low. So the negative frequency of these two can cause passengers not hear anything.

The method used is to increase the hardness or increase the weight of the equipment. Then the frequency of the oscillation will change.

Frequently Asked Questions (FAQs)

Beside all the information about grinding noise when turning above, we also collect some frequently asked questions about this situations to make clear. All of the questions just focus on one thing that their car always grinds noise while turning, and they want to ask for any solutions to reduce this grinding sound when turning. So let’s take a look for some answer below to ensure your decisions while fixing this situation.

Can you guys advice for me about this problem?

My car in the morning when starting the engine is often very noisy and light vibration, I often have to run for a long time until the machine is hot enough so phenomenon is reduced. Of course, I understand when starting, the engine will be gas compensated so it turns a little bit faster, but the problem is that the car is noisy and vibrate abnormally, standing beside and listening to the fence is almost sitting in the airplane. Some people told me to replace the tripod, but when I put into the firm as well as the garage, they are all answered the tripod is not starred.

So if anyone has ever been in this situation like me? And if so, how do you handle it?

So here are some answer that can relate to the question and give back to you enough knowledge about this problem, make sure to check your car type first, and then we can continue the process of fixing the grinding noise when turning the car.

– It can be caused by ignition, or by gas or wind, which is one of the causes of this condition. Take a look to your round machine whether is it steady or not?

– It is possible that the rubber legs are aging, losing the elasticity while the machine was cold, but not broken or deformed so the garage said that the car does not matter.

– As you describe about the problem, I guess your car have 02 problems:

There was a gap in the size of the su-pap

The lubricant for the su-pap meets problem, may be due to oil narrowing, oil pump weak or oil too condensed.

The quickest way is to check the oil level, oil viscosity of the machine. The faster you change, the less you meet this problem.

Also in the garage, you ask the mechanic to open the lid of the check valve, then start the machine to check the oil on the stalk, it is necessary to change the oil suitable machine.

– It is caused by vibration, but the reason why the engine cooled down was because the ignition system is operating according to the signal of the temperature sensor, when the engine pre-ignition angle must be larger to burn more radical fuel. The machine will vibrate. This is a common feature of all vehicles, but the level of each specific car is different. If you want to reduce the vibration, you just need to increase the fringe, it will be fine.

Your car is a complex machine with countless parts working in perfect harmony. Even a small damage somewhere can greatly affect how a car runs, or whether it runs at all. When you detect any abnormalities, such as grinding noises when turning, troubleshoot right away.
