Why do throwout bearings go bad

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. This should be a red flag for any driver, and should be addressed right away. Any transmission issue inevitably leads to issues shifting gears.

Finally, a bad throw-out bearing can lead to total clutch failure. Though throw-out bearing failure is more common in some cars over others, every automobile is vulnerable to throw-out bearing wear over time. One of the easiest ways to prolong throw-out bearing wear is to adjust the way you engage the clutch pedal in your car.

All these noises can be pinpointed to the transmission area. You will likely hear these sounds the most when you press down on the clutch pedal, but you may still hear them with the clutch fully engaged. If you press down on the clutch pedal and feel vibrations going into your foot, this is likely due to a bad clutch release bearing. The reason these vibrations form is that the bearing cannot connect to the pressure plate evenly, or there is wear inside the bearing itself that is causing it to vibrate with age.

This generates a pulsation effect that will come out of the pedal and be felt in your foot. These vibrations are likely to be accompanied with strange sounds as well. If you notice these vibrations when you are accelerating or braking , there are some other components you will want to check out as well such as your brakes, wheel bearings, and axles. The replacement cost of a throw out bearing will not be cheap.

If you have dropped your transmission before, you should be able to change your throw out bearing without too much trouble.

This task is a bit more involved for a DIY mechanic, but it is something you could do in your own garage if you have the right tools, a repair manual, and good attention to detail. When you go to change the clutch, you generally should change the throw out bearing at the same time while you have easy access to it.

I drive a chev utility I started to feel vibration when changing gear and after few days when I was driving it on the way the car start to be weak and no power at all. I have the Mk2 fitted with a new Clutch for Mk1 Jetta but since then the release bearing became stuck and the clutch cable so by hard to pull. I would argue that this would kill the pilot bearing, not tob Sounds like bad grease, too high of temp, or bad spacing.

Another problem with the clutch pedal besides the clutch pedal feeling strange is vibrations felt through the pedal. When this bearing is working as it should, your clutch will move down smoothly and quickly, but if you start noticing the vibrations coming from the pedal into your foot, this is a clear sign that your throwout bearing is damaged and is causing issues with the clutch.

Since you need the clutch to change gears, if any part of the clutch assembly fails or is not working properly, it will make it very difficult and sometimes impossible to shift gears.

This leads to lack of engine performance and can cause the bad throwout bearing to only get worse over time. If you notice any problems with changing ears, like unsmooth shifting, delayed shifting, or problems with reaching a certain gear, this can be a clear indication that you have a problem with the throwout bearing that can negatively affect your transmission.

If you let all of the above symptoms go on for too long without doing any fixes or repairs in the clutch system and the transmission, then you will eventually experience a total clutch failure. The total clutch failure is nearly impossible to miss or ignore, since the result is you will not be able to power or drive your vehicle at all. Total clutch failure is a very expensive repair and replacement in your vehicle, up in the ranks with engine failure and transmission issues.

Since the clutch system relies on the other three components to work correctly, like the flywheel, pressure plate, and clutch plate. If any of these symptoms are damaged, your clutch will not be usable, rendering the throwout bearing unusable. Although the throwout bearing becomes damaged in some situations is out of your control and cannot be prevented, in some cases, this issue can be remedied and prevented by adhering to the following guidelines.

One of the ways to prevent a failure of the throwout bearing or prevent a damaged throwout bearing is to inspect and analyze the clutch assembly and the transmission system.
