If your vehicle has a manual transmission (a rarity these days), you need to be able to operate a clutch pedal in addition to the brake and gas pedals.
The clutch assembly (consisting of the pressure plate, clutch plate, flywheel, and throw-out bearing), connects the wheels to the engine of the vehicle. The clutch pedal gives you the ability to temporarily disconnect the wheels from the engine which is needed when shifting gears.
The throw-out bearing, sometimes called a “clutch release bearing”, is a simple yet important component that’s only in use when the clutch pedal is depressed. When you have a bad throw-out bearing, it will affect shifting and can lead to failure of other clutch and transmission components.

How a Throw-Out Bearing Works
In short, a throw-out bearing is the component of the clutch which temporarily disengages a car’s engine from the transmission during gear shifts. When you push the clutch pedal with your foot, the clutch release bearing gets closer to the flywheel.
This causes the release fingers of the pressure plate to get pushed in. Once that happens, the fingers of the pressure plate push against the force of its spring. This causes the disconnect between the engine and wheels and allows you to shift into a different gear.
When the clutch pedal is released, the throw-out bearing returns to its original position where power from the vehicle’s engine once again is transferred through the transmission into the drive wheels of a car.
Common Bad Throw-Out Bearing Symptoms
All the components of the clutch and transmission system are important for the safety and functionality of the vehicle. If your throw-out bearing is unable to do its job properly, you’re going to notice some signs of it starting to go bad or complete failure.
The bearing may go bad after years of wear and tear or maybe even from damage due to an accident. In any case, you need to get the clutch release bearing replaced as soon as you notice it’s having problems.
Below are the top 4 symptoms of a bad clutch release bearing.
#1 – Strange Noises
The most common sign of a bad throw-out bearing is when you hear various noises when you depress the clutch pedal. The rollers within the bearing have a tight tolerance and are supposed to be close together.
But if there is too much space between the rollers, then different types of noises will start to be heard. These can include rattling, grinding, squealing, growling, or whirling sounds.
This is simply due to the rollers in the bearing wearing out over time and losing small amounts of material. The noise will sound like it’s coming from the transmission area.
The sound will be most noticeable with the clutch pedal fully depressed and go away when you take your foot off the pedal.
#2 – Clutch Pedal Vibrations
When you press down on the clutch pedal, it should move down smoothly. But if you start to feel vibrations coming from the pedal, then it’s very likely that your clutch release bearing is defective or has failed.
More specifically, the vibrations are the result of the throw-out bearing being unable to properly line up with the pressure plate. Your foot will feel pulsations as this happens.
The vibrating pedal is similar to how a brake pedal would feel if the disc brakes or brake pads were unevenly worn.
#3 – Gear Shifting Issues
Gear shifts should be smooth without much resistance. If you notice you’re starting to have some difficulty shifting or even grinding gears, it’s possible the throw-out bearing has gone bad.
The problem is that your clutch is not fully engaging. This shouldn’t be the first symptom you experience from this problem, though.
You should hear those strange noises first. If you continue to let that issue go unfixed, then you can expect gear shifting issues or clutch slipping to follow.
#4 – Clutch is Too Stiff
Like most components of the transmission system, the clutch release bearing is manufactured with special lubrication properties to keep it working smoothly for a long time. Unfortunately, the lubrication properties will wear down as the bearing itself wears down.
The more worn down the bearing is, the harder it will become to depress the clutch pedal. It will soon get to a point where you cannot disengage the clutch. Then you won’t be able to drive your vehicle at all since you won’t be able to shift gears.

Since it is a simple part, a throw-out bearing itself is relatively inexpensive. The problem is the amount of labor it takes to get to it since the entire transmission needs to be removed.
Because of that, it’s usually recommended to also replace the clutch (and sometimes flywheel) while in there.
A throw-out bearing will cost you anywhere from $30-$100. The price of a new clutch can vary greatly depending on the vehicle but most cost somewhere in the range of $300 to $800. A new flywheel (if needed) will set you back another $50 to $200.
As mentioned, labor costs when replacing the throw-out bearing is where you’ll spend the most money. Your mechanic will need 4 to 6 hours to replace the throw-out bearing and clutch so at an average $85/hour labor rate, you’re looking at about $340-$510 just in labor.
All told, the total cost to replace just your throw-out bearing would be $370 to $610. But you will likely want to replace your clutch at the same time so the total replacement cost would be more along the lines of $670 to $1410.
My release bearing keeps on breaking have changed this for the 4 time and l dnt know what is the cause of this
Assuming you’re not holding down the clutch pedal for more than 1-2 seconds at a time when needed, it’s likely some type of alignment issue. Make sure the pedal itself doesn’t need adjusting. Otherwise, something off/bent on the pressure plate could be the issue.
My RX8 was doing just the opposite. Press the clutch in and the noise stopped. Take your foot off and it starts making a noise again.
Same issue here with my 94 Mustang
I READ THAT ALSO. (?) I AGREE, MY 2017 WRX IS DOING THE SAME AS YOURS.
The 2015-2018 WRX has a technical service bulletin (TSB) for the throw out bearing. https://static.nhtsa.gov/odi/tsbs/2018/MC-10150949-9999.pdf
Have you fixed the problem
My jetta 3 vw got problem with clutch wen I press down clutch pedal it doesn’t come back BT I change clutch cable and clutch place BT still the same 0726715590
Hi this will be your slave cylinder starting to fail. It’s the hydraulic part if the clutch and unfortunately when it goes you will need to replace the whole clutch as most cylinders are located inside bell housing.
I had a ahm clutch fitted on my aston martin vantage 2006 3000 miles ago shortly after i had problems with the pedal sticking down it is now in the garage & been stripped i inspected the clutch and the bearing has excessive wear on one edge & the plate fingers on the pressure plate show that it had been running at an angle what could cause this.
Almost sounds like the clutch was not aligned correctly during the install. Or was the old clutch the original? I’m sure the labor costs to replace the clutch on an Aston Martin are crazy high so I feel for you.
Not torqued evenly perhaps.
Changing of gears on my tata 1518 truck is hard. What could be the problem
I fitted Toyota 4y engine with 5 speed gear box in Isuzu, KB260 body, prop shaft was machined, at times wen I engage in gear 2 wen starting to move the Bakkie drugs wen releasing the clutch , what could be the cause ?
my 2007 Dodge Nitro throw out bearing and clutch assembly was replaced. Now I’m hearing rattling noise. what has gone wrong?
Spring clip that holds the TOB tight to the clutch fork get bent? A lot of times it gets bent during instillation to fit the TOB on easier and the space between the two results in a rhythmic clicking or rattle.
My 2014 kia rio shifts just fine when the engine is cold but as soon as the engine heats up I start having hard shifts and can nearly put the car in reverse. Please what cold be the problem? Thanks
Just changed my throwout bearing, but my clutch is still soft and making grounding noises what could be the problem now?
Maybe Input Shaft Bearing
Hi my fly wheel is my problem .Can a bad flywheel ,make the car unable to turn over and start .Can anyone tell me ??
Hello I have a 1994 Toyota 4 runner manual and at first my cluch was sticking and messed with the cluch rod and was good for a few miles but as I was driving and shifted in to 5th gear I lost complete function of all my gears there is no resistance at all can someone please help, could it be my throw out barring
If there is no resistance, it may mean you have air in the lines, or most of the clutch fluid has leaked out. Have a look at the following article and see if it matches your symptoms. http://cartreatments.com/bad-clutch-master-cylinder-symptoms/
My transmission makes a rattling noise when you let the clutch out when you push it in it disappears it has a brand new stage 4 clutch pressure plate and throwout bearing in it right after I replaced it all it was still making noise it was making noise before that but a squealing noise and so I thought I had to replace my throwout bearing and plus it would burn clutches just shifting normally now it don’t burn clutches anymore it but it does make a rattling noise and it’s been getting worse but it goes away when you push in the clutch what is it
Sounds like it could be the throwout bearing. It sounds pretty bad; I am guessing someone will have to drop the transmission to know for sure what the root cause is.
Possibly wear on the fork pivot point.That would explain why no rattle when applying pressure to it.
….That sounds like your going to need a rebuild. Your clutch/transmission might be starting to go, I would most likely assume. When the engine and transmission heats up, the oil gets thinner, which causes less pressure. When it is cold, the oil is thicker and creates more pressure. You also could have a leak in the tranny lines, among other things. There could be a couple other culprits, but this sounds like your clutch is going to be needing a rebuild as the gears eventually wear down, along with the fluid ends up wearing out, too, which could be caused by the wear of the gears. It happens after so long and may need to be rebuilt or you could take it to a shop that could diagnose the problem. Just be careful as you never know what it might be and you might end up wasting tons of money on repairs IF it is something simpler. Hope this helps. Good luck with this! It is definitely not cheap for the rebuild. I wish you the best!
I have a Kia Spectrum 2006, my gear shift okay when the engines off but when the engines on I cannot go into gear it wants to move a little bit but won’t go anywhere any help
Sounds like your clutch isn’t disengaging all the way and your clutch pedal may need an adjustment. Have you checked the clutch fluid and tried adjusting the clutch pedal?
Hi,
I have a 3 1/2 year old Dacia Sandero Stepway 2, 1.5cc Diesel, and driven 70000km. Guarantee expired after 3 years.
I’m no car expert at all :/. Fairly recently I began to hear something resonating as I feather the clutch pedal. In neutral there is already a rattle but that is normal I think but seems to become louder when the pedal is partial pressed but then disappears when the pedal is fully depressed.
Is it the throw-out bearing that rattles ? A few weeks ago I hit a pothole hidden under water. I cannot remember is the sound was there then. Could that have damaged the bearings ?
my hyundai i10 1.1. the replaced the complete clutch. the cable was feeling sticky and hard when compressed. so i replaced the cable. but now the pedal is gone stiff like a rock and when i press the pedal down to engage the clutch. the cable makes a whining squeal like sound and suffer to get into gears . the release fork feels like its seized so i really cant be sure what needs fixing next. please help someone.
Li just had the whole clutch put in it hasn’t been long since I got this put in now the pedals at the floor I can bring it back up if I keep in neutral it’s starts back up so where’s the fluid go what do I need for fluids it goes to the floor I pick it up it works till I stop I need help put allready a grand into it
Check your clutch fluid level. I would bleed the clutch also to make sure you don’t have any air in the lines.
Hey folks,
I have a 2000 Subaru/LEGACY/OUTBACK LIMITED, when i release the clutch it makes a squealing noise. Is this a throw out bearing issue? Would it be difficult for a novice to repair himself, if so?
Any insight would be appreciated.
Sounds like it may be the throw out bearing. If so, replacing the throw out bearing would require you to either pull the engine or drop the transmission. Pulling an engine on those old Outbacks isn’t too hard if you already have experience working in the garage. You just need a cherry picker (also called an engine crane) and ideally an engine stand. If you’ve never done this before, it’s best to do this job with another person who’s done it before.
Hi all,
My issue is quite different than yours, when i depress the clutch pedal, it gets stuck exactly at the point where the gear should be engaged, and then noise is made like metal parts are hitting each other and after sticking there temporarily then returns to the original position. The fact that it sticks there for these moments and the normal movement of pedal depress is altered, makes the clutch to engage very suddenly and the car jumps to the front.
Any idea what could be the cause of this issue please?
I would suspect an issue with the throw-out bearing, the pressure plate, or the clutch fork. Before dropping the transmission, double check to make sure you don’t have any air in the clutch lines.
