Throwout Bearing Noise

Throwout Bearing Noise – Should You Be Worried?

So, are you experiencing noise coming from your manual transmission? This is a noise so weird that you don’t know what is really going on since the shifter is working properly. But let me tell you, that you are probably experiencing a throwout bearing noise.

Manual transmissions are pretty cool because you have the freedom of shifting gears at whatever RPM range you desire. You can short shift, downshift, and enjoy your car’s performance. Personally, I have a manual transmission and I wouldn’t change it for anything else on this planet.

But that’s why manual transmissions have more parts that are essential to work such as the clutch, flywheel, pressure plate, and a throwout bearing.

If you press the clutch pedal, the clutch disengages. When you release the clutch pedal, the clutch engages and shifts your gears up or down. It’s pretty simple. That’s why manual transmissions are the best because they’re so simple. You don’t have a torque converter and all that jazz. This makes them pretty affordable and really fun to drive.

Many people hate them because they are difficult to learn, but in life, you need to enjoy the challenges. Learning to drive a manual is one of them. Even though it’s so complex to learn you’ll figure it out on the second try.

In this article, we are going to cover everything you need to know when you are experiencing a throwout bearing noise. We will learn what are the main symptoms when you are having this issue and we are going to learn how this issue can be addressed. Also, we will give some advice on how to prevent it in the first place. This is because the throwout bearing is a big repair job if it breaks, which requires a lot of work hours. So. let’s begin.

What Is A Manual Transmission?

As the name implies, a manual transmission is an automotive gearbox where you have to change the gears manually if you want to go in a higher or lower gear.

This is unlike the automatic transmission in which you have two pedals – one gas, and one brake pedal. In manual transmission cars, you have three pedals. These would be the gas pedal, brake pedal, and clutch pedal. The clutch pedal is what’s performing all the magic of shifting gears.

Basically, you are working it by pressing and releasing the clutch pedal. By pressing and releasing the clutch pedal you are engaging and disengaging the clutch of the car. This is unlike the automatics in which you have a torque converter. In manual transmissions, you have a clutch plate, flywheel, pressure plate, and a throwout bearing.

This clutch assembly is what’s engaging and disengaging. These parts wear out with time or through improper use. If you’re bad at shifting, then you will probably burn out your clutch pretty soon. Also, the throwout bearing is known to suffer and develop a throwout bearing noise.

That’s why to save your clutch when you are learning to drive a manual transmission, you should always try to not overheat your clutch and throwout bearing. This can prematurely wear these components and can cost a lot of money to fix.

Clutches usually have a 150,000 miles lifespan on them when they’re new. But if you abuse them for racing or with improper shifting, you will reduce this lifespan to a few thousand miles.

The repair bill will be around $1,000 for all the parts and the labor. That’s because if you want to remove the clutch and replace it, you will have to remove the whole transmission and clutch assembly.

What Is A Throwout Bearing?

The throwout bearing is one of the most essential parts of the shifting process. This bearing makes all this possible, and you have the ability to shift effortlessly. This bearing makes the clutch release look very easy.

The clutch release bearing or a throwout bearing typically is a thrust-type angular contact ball bearing and is supported on a carrier.

This clutch release bearing is mounted on a hub or sleeve that extends the gearbox. This ball bearing is perfectly made to fit your gearbox sleeve. The sleeve is the part that protrudes from the inside of the gearbox.

This bearing is mounted before the release fork. So, when you engage and disengage the clutch. This fork moves in and out.

When you engage the clutch, the fork is moving the bearing into the diaphragm spring fingers. This action makes the throwout bearing rotate and absorb the rotary motion of the spring fingers against the linear motion of the fork.

Although it seems complicated to explain, you need to see how this bearing works in action first. On YouTube, there are a ton of educational videos on this topic and you can clearly see and understand the throwout bearing function in detail.

This bearing basically does all the hard work in engaging and disengaging the clutch. This makes it an essential part that drives your car forward. That’s why when you hear throwout bearing noise, you have to act quickly and get it resolved. If you delay this, it can hurt your clutch. That’s especially if you have a clutch that has a lot of life in it. In the end, it may be very expensive to get this fixed.

But in this chapter, we are going to cover all of the symptoms that you will have when you are having a bad throwout bearing problem in your car. So, let’s begin.

1. Throwout Bearing Noises

Throwout bearing noise is the most common symptom when you are having a throwout bearing issue on your transmission. This noise usually appears when you are engaging the clutch. When you put the foot to the floor the bearing stops making weird noises. Then you release the clutch these noises start to reappear. That is how you can diagnose this issue.

The sound of the throwout bearing is like a squeaking noise that quickly comes on and off. We’re talking about milliseconds here. Once you hear it, it is pretty easy to diagnose.

This can be a bit annoying when you are having an issue like this. And you will think that something is seriously wrong with your transmission. But you should not panic and stay focused on driving. Don’t let a thing like a throwout bearing noise distract you.

2. Vibrations When You Apply The Clutch

This is an instant sign that you have a throwout bearing issue. When you apply the clutch instantly there are vibrations and noises. These vibrations and noises last until you press the clutch pedal harder and start to engage the clutch.

When you apply more pressure on the clutch pedal and press it down to the floor, all of the vibrations will magically disappear. This will continue you release the clutch with your foot. Once you release the clutch, again the throwout bearing noise and vibrations start to appear.

These can be a bit annoying. However, they are there to tell you that you have a problem with your vehicle and this requires solving it as quickly as possible. Make sure that you book an appointment with your local mechanic to further investigate this issue and find the problem.

3. Gear Shifting Problems

Gear shifting problems may also appear when you are having a bad throwout bearing. This problem will be most pronounced when the bearing is almost done and doesn’t do its job properly. This problem can make you feel like you are feeling resistance when you move your gear lever in gear.

Some weird sounds may start to appear like something inside of the gearbox is breaking or everything is broken. But this resistance and metallic sounds appear because your clutch isn’t fully engaging. This creates more confusion, as you think that everything inside is broken. But you shouldn’t panic. Although if you do not take care of this issue soon, some gear shifting issues may appear and you may damage your transmission.

That’s why when you are dealing with some of these problems, the best thing is to resolve this problem as soon as possible. You don’t want to pay a double price at the end.

4. Stiff Clutch

A stiff clutch can also be one of the symptoms that you can experience if your throwout bearing is broken. This is the case because the bearing inside is broken and does not have the same lubrication. This means that it has a lot of friction and the throwout bearing will get more damaged. This will cause your clutch to get stiffer and stiffer.

It will be a lot harder to depress the clutch pedal when you have a worn bearing. And eventually, when the bearing will be completely gone, you will reach a point where you will not be able to disengage the clutch anymore. Since you will not be able to disengage the clutch, you can’t drive the car and shift gears. Possibly, and if you can get your gearbox into the second gear, you may be able to limp to the workshop at 20 mph.

If you are not able to drive your car, then the best idea is to call someone to take your car to the mechanic’s shop. You don’t want to drive a car that isn’t road-worthy because you can be fined in some situations.

5. Clutch Failure

As we said. If the bearing is pressed and is rubbing the clutch all the time, there will be consequences. In the worst-case scenario, your clutch will start to smoke and will wear out. When a clutch is failing you will be able to recognize this issue by the cloud of smoke it creates and the inability of the car to move when you get it into gear.

Also, the smell. The smell is terrible, like rotten eggs. But much worse. When you are experiencing a clutch failure you will notice it sooner or later. You should have this mended before it gets worse and causes your car to not be able to move.

If you have a bad throwout bearing and your clutch is almost done, then it’s best to get this work done altogether. Since the transmission needs to be pulled out. The best thing is to replace all of these parts at once. It’s going to be a lot cheaper for you at the end of the day.

How To Diagnose This Issue?

Check-VSC-System

To be sure that your throwout bearing is failing you can do some tests to troubleshoot the issue and find if the throwout bearing is really the problem. Now, we are going to explain how you can do that.

To do this, you need to go for a test drive. You should try to listen to the noises when you have pressed the clutch pedal to the floor. Put your car in first gear and release the clutch. If there is some odd sound, you are probably having a throwout bearing issue or a worn pilot bearing.

So, to isolate the two bearings and have a better idea of which one of them has failed you need to keep the clutch pedal to the floor, and then shift into neutral. If the noise is still there, then your throwout bearing is done. And if the noise in this case disappears, then the pilot bearing is broken.

Let’s say there is bearing noise when you are releasing the clutch pedal to engage the clutch while you are in neutral. But then the noise goes away the pedal is depressed. This is usually caused by a broken transmission input shaft bearing.

This simple guide is going to help you diagnose this issue and hopefully find the possible culprit. You have to have good ears to understand this problem and diagnose it. Even though you diagnosed it, the transmission still needs removal and work has to be done on the car.

This is not a simple job as we mentioned. In the next chapter, we are going to learn how to replace a throwout bearing DIY. This is important because if you want to replace the bearing by yourself.

Replacing A Throwout Bearing DIY

Before we start, this job is very complex and is usually a two-man job. This is because there are a lot of steps and many parts need to come off the car before you get to the bearing. The bearing may be small, but it requires a lot of work to be pulled out from the car and replaced with a new one.

But that’s why we are car guys are here, right? We want to wrench and do the work on our cars by ourselves. And in this chapter, we are going to guide you into the process of removing the bearing from your transmission and replacing it with a new one. So, let’s begin.

Step 1

Step 1 involves removing the transmission of the car. To remove the transmission, you have to jack the car in the air. Or preferably, on a lift. Then you will need to get some support that is going to hold the transmission and slowly bring it down, so you have a proper working environment. Removing the transmission is essential and you cannot do this job without it.

Step 2

Now you need to locate the bearing. The bearing is located right after the fork. The bearing is mounted on the sleeve in the center of the transmission.

Step 3

The old bearing should come off pretty easy and you will only need a slight tap with a rubber mallet to get it loose if it’s stuck. If it’s an old bearing, it’s probably left without grease and it will be harder to pull it out.

Step 4

Now you have to grease the new bearing and grease the sleeve that the bearing is mounted to. This is important because the grease will keep your bearing healthy and will make sure that it has a long life. Not only this bearing, but any bearing that you install on your car, it is always a good idea to put a lot of grease on it before you install it on the car.

Step 5

Since you greased the bearing now it’s time to reassemble. Install the bearing in the right direction and mount the transmission back in its place. Make sure that you tighten all the bolts and everything is properly connected. Then you are good to go.

Pro-Tip

Since you are removing the transmission. It is a good idea to check the clutch. If the clutch is near its lifespan, then it is a good idea to replace it altogether. You don’t want to do this job again after few months. Also, by doing this you will avoid paying twice to mechanics.

Throwout Bearing Replacement Cost

The throwout bearing is a relatively cheap and affordable part. It can cost around $30 to $100 to buy. If you add the clutch to this price you will come at $200 to $800 for the clutch. Clutches are relatively expensive. So, don’t burn your clutch. All in all, for the parts it can come to $400 for a regular commuter car. If you have a sports car this clutch job is going to be far more expensive.

Parts are relatively reasonably priced but there is also the labor factor. The labor for this job can be costly. There are a couple of hours of work into this job. And this adds up pretty quickly. Depending on the place you take your car to it can cost you a lot of money to get it fixed.

That’s why we recommend doing the clutch job along with the throwout bearing. It will be much cheaper to do in the long run. Imagine if you change your bearing and the clutch fails after few months. The transmission has to come out again and again you will lose money on mechanics.

How To Prevent The Throwout Bearing From Failing?

To prevent the throwout bearing from failing you need to perfect your shifting skills. Spend as little time on the clutch pedal when you are shifting gears. The less time you spent with your foot pressed to the floor the less the throwout bearing will suffer and possibly get damaged.

Many people think that they shift perfectly but that’s not the case. When you press the clutch, change gear and release completely. The more you hold your feet pressed, the more load on the clutch and the throwout bearing. This results in possible damage and wear.

Is It Ok To Drive A Car Like This?

Driving like this with a bad throwout bearing is not recommended. Since you are hearing a throwout bearing noise it means that you need to get this thing checked.

If the whole bearing fails, you will not be able to shift gears and eventually you are going to end up stuck and you will not be able to move your car around.
