Clutch has noise when pressing clutch pedal
I have started hearing a noise when I press on the clutch. This happens when it is damp in the early mornings, before it gets hot. I recorded the noise so I could play it to the dealer, which I did when I took the car in and left it overnight. The technician listened to the noise and said it was faint and didn’t cause any mechanical problems and wouldn’t be under warranty, so they did nothing. I am concerned that the clutch will be damaged. What can I do to get this problem corrected so the clutch will work properly?
Experienced mechanics share their insights in answering this question :
Hey there, a noise when pressing the clutch is generally tied to the throw out bearing or release bearing. It may be necessary to replace the throwout bearing and have the clutch assembly inspected while the transmission is out of the vehicle. If you want to have this taken care of, a certified professional from YourMechanic can inspect the noise and have this issue corrected.
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
Whistling or whining from the clutch can be caused e.g. by the release bearing running off-center, an off-center input shaft, or a defective pilot bearing. On the other hand, rattling noises may be due to load alterations if clutch disks are furnished with preliminary dampers.
Worn Throw Out Bearing: If you notice the noise from your clutch when you release the pedal, chances are good that the throw out bearing is failing and will need to be replaced.
That`s the clutch release bearing causing the noise (happens when the clutch is pressed and goes away on releasing). The noise is not serious but it can be annoying in city traffic.
Noise under this condition indicates a worn release bearing or a worn pilot bearing. To isolate the two, keep the clutch pedal on the floor and shift the transmission into neutral. If the noise persists, the release bearing is bad. If the noise is gone, the pilot bearing is bad.
Your clutch system can produce a number of different noises. These are some of the common noises: Growls and Squeals: Noises like these are usually caused by worn release or pilot bearings. Chirping: Vibrations in the actuator system cause these noises, this is usually due to worn contact points on the pivot ball.
How long will a noisy clutch release bearing last? If your clutch is making unusual noises when you push the pedal down you should take your car to a mechanic as soon as possible. A noisy clutch release bearing might last a hundred more miles, or it might not, but that isn`t a risk you should be willing to take.
Chatter is shaking or shuddering that is felt when the clutch is engaged. Chattering is evident while the clutch is being engaged and stops when the clutch is fully engaged. Clutch chatter is usually caused by contamination of the clutch disc friction surfaces.
It really boils down to your driving experience. Chatter usually happens as the clutch is engaging. It occurs when the pressure plate is alternatively grabbing and slipping the clutch disc, making the car shake as the engagement is occurring.
It is typical for drivers to hear a grinding or rattling sound when pressing down on the clutch pedal if the throw-out bearing is bad. These noises are concerning, but they could point toward other issues with your transmission or clutch, so a differential diagnosis is in order.
That said, it`s a really bad idea to drive with a worn clutch thrust bearing. Sooner or later it`s going to explode and do a lot of damage.
The average lifespan of a clutch is anywhere between 20,000 to 150,000 miles. Luckily, your clutch will likely give you ample notice that something is going wrong. Don`t get left at the side of the road with a vehicle that won`t shift into gear.
Use a low-pressure-type grease gun equipped with the recommended grease, and lubricate the bearing until excess grease purges from the rear of the release bearing (toward the transmission). Do not over-lubricate the clutch release bearing.
Most of the time, yours should get you anywhere between 60,000 and 100,000 miles before you`ll need to replace it. If you want your clutch to last even longer than that predicted lifespan, try not to accelerate too harshly or drive the car too hard, as this can put extra stress on the system.
If you hear a whining or loud grinding sound coming from underneath your vehicle as you press the clutch pedal down to the floor, it may be caused by a throw out bearing that is damaged and need to be replaced.
The classic sounds of a bad wheel bearing are cyclic chirping, squealing and/or growling noise. You can also tell that the sound is related to wheel bearings if it changes in proportion to vehicle speed. The sound can get worse with every turn, or it can disappear momentarily.
As a rule of thumb, the lifespan of a release bearing is 150,000 kilometres. If the clutch is used incorrectly as described above, this can drop to as little as 50,000 km.
The classic symptom of a worn throw-out bearing is a whirring or growling sound when applying the clutch pedal, which goes away when releasing the pedal. Premature wear of the throw-out bearing can occur when there is insufficient clutch play, resulting in a throw-out bearing that spins continuously.
A defective release bearing causes friction, which is why the noises usually sound scratchy or like grinding. If the defect is well advanced, you will notice the problem through so-called clutch slippage, i.e. the car does not accelerate properly even though you changed the gear and the engine speed increased.
A worn or damaged pilot bearing will make a whining or grinding noise. It will be very loud if the bearing is completely damaged. It occurs whenever the crankshaft and input shaft are rotating at different speeds.
Clutches are repaired or replaced on condition, not mileage. I have had four vehicles with clutches that I drove nearly 300,000 miles each without needing clutch repair or replacement. Learn how to properly use a clutch.
This legendary engine was essential for rally race wins and is famous for its distinguishable growl. Drivers have reported that the boxer four-cylinder can last up to 250,000 miles with proper care. On the other hand, pushing your WRX past its limits could wear out the engine at only 60,000 miles.

My clutch pedal is stuck to the floor. A while back I started hearing noise in my clutch when I pressed it. The car drive fine, th
ANSWER : Your vehicle uses a hydraulically operated clutch system. The first thing to do is check the fluid level in the master cylinder and check for leaks although leaks at the slave cylinder might not be apparent. Internal seal failures can cause the same problem that one might experience (i.e., no clutch operation) with visible leaks and a low fluid level. The noise may be due to a failed clutch release bearing. Due to the noise and the misoperation, if the slave cylinder turns out to be faulty, you will probably need a new clutch as well as hydraulic components. The cause of the fault that you are reporting can be pinpointed if you request a hydraulic clutch system diagnostic. If you request that diagnostic, the responding certified mechanic will get this diagnosed and let you know exactly what must be done. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

My pedal makes a grinding noise and gears get stuck
ANSWER : It could be that you haven’t gotten all of the air out of the system. Bleeding the clutch carefully may solve the problem. Or it may be that the Clutch Master Cylinder is also worn out. Often I just recommend replacing both to keep from having the hassle of one wearing out shortly after the other. The third possibility is that there is a problem with the clutch itself. An experienced technician can tell you pretty quickly where this problem lies. If you contact Your Mechanic, you can have a technician come out to your home or office to check out your Acura and recommend a fix

I can’t go into 4th or 5th gear and clutch does not engage after a recent clutch job, clutch release while in gear does nothing.
ANSWER : I would rule out the axle not being pushed all the way in. That would effect all speeds and gears. That you can engage gears other than 4th and 5th leads me to 2 m possibilities:
1. Shift linkage mis-adjusted.
2. Possible bent shifter fork internally.
1. Shift linkage mis-adjusted.
2. Possible bent shifter fork internally.
If it feels like you can engage 4th and 5th with the engine OFF, then I would lean towards a clutch release issue.

Clutch pedal stays to floor. Replaced master cylinder. Clutch push rod broke. Also do I need to change slave cylinder
ANSWER : If you have an issue with your clutch pedal going to the floor, the slave cylinder is normally the cause of this circumstance.
Also, if the push rod has been broken the first step would be to track down a new one because that push rod is a very necessary part of the clutch pedal system.
Once a new push rod has been located and installed, I would recommend having a new slave cylinder installed as well.
If you are in doubt about this repair, I would recommend having it performed by a qualified professional, such as one from YourMechanic. One of our mobile technicians will be able to come to your home to diagnose the issue with your clutch pedal and replace your clutch slave cylinder as necessary.

Clutch pedal goes to floor when pressed
ANSWER : With the symptoms you have described, the most likely cause is a leak in the clutch hydraulic system. If there is a leak on the system it causes air to enter. Since air is not able to be compressed the clutch pedal remains stuck to the floor when it is pressed down. With everything going on with this car, it is unsafe to be driven until the clutch has been repaired. A qualified technician, like one from YourMechanic, will be able to confirm the cause of your clutch issue and perform the needed repairs to get you back on the road.

Clutch not working after replacing slave cylinder and master cylinder
ANSWER : Hello. We will be happy to help you with your vehicle. It sounds like you have a problem with your throw out bearing. You would likely need to drop the transmission once again and check that the installation of the throwout bearing is proper. You may also try to peel back the boot around the slave cylinder to see inside of the transmission. By doing so you may be able to see possible damages on the throwout bearing. It will be a great idea to use a stethoscope before you take the vehicle back apart to help pinpoint exactly what portion of the transmission coming from. Another very important thing that you should check are your axle’s, make sure they are seated correctly inside of the transmission.
