Throwout bearing is one of the clutch assemblies that can affect the car’s functioning. It plays a significant role when the clutch pedal is damaged. If it becomes bad, the transmission and clutch components fail, causing further problems (such as you can’t change the gear). To avoid such a condition, you should know what causes a throwout bearing to go bad first?
A throwout bearing can go bad at any time. For example, it can go wrong due to prolonged use or hard use. Besides, sometimes drivers keep their foot on the pedal for resting by mistake that can cause throwout bearing to go wrong.
Technically, some other reasons can make your throwout bearing failure. Today, I will try to reveal all those in detail.

What is a throwout bearing?
Technically saying, throwout bearing is also known as release bearing or clutch release bearing or sealed ball bearing ~ HOT ROD
It is one of the 4 key components of the transmission process, with the others being pressure plate, clutch plate, and flywheel. It can make the gear changing smooth enough by removing the transmission from the car’s engine.
Besides, release bearing controls the total of contact between the flywheel and clutch plate.
What does a throwout bearing do?
Throwout bearing gives attachment to the pressure plate to release the plate from pressing the clutch plate onto the flywheel area before changing gear ~Willy Roentgen (Registered Professional Engineer)
Clutch release bearing is used on cars with a manual transmission that releases the clutch when the driver pushes down on the clutch pedal ~Jesse Gutierrez (Diesel Mechanic at Freightliner).
The throw out bearing presses the levers that free the clutch while pressing the clutch pedal down. As those levers are spinning, the sealed ball bearing spins as well. (It is the pink part of the diagram) ~ James Pearson, ASE-certified master truck tech, retired Army motor SGT.
With this bearing, a stationary surface and moving surface can be connected to each other.
Besides, it stops ultimate heat and friction when the clutch is deactivated “unveiled” to stop power to a rotating shaft.
What causes a throwout bearing to go bad?
Of course, throwout bearing will go bad with usage. But most often, the failure of this component depends on the driver and style (Driving Habit).
- According to Kai Herrmann, an expert mechanic claimed that throwout bearing may go wrong due to the shifting at high speeds (In a fraction of a second, spinning it up to 8000rpm).
- After years of wear and tear, the clutch release bearing may go bad, or because of an accident, it might be damaged.
- If lubrication properties wear down, it might go wrong.
- It’s the pressure plate that can make it go bad faster.
- Heat is probably one of the suspects that can lead the bearing to go bad.
- Probably, running 20,000 to 30,000 miles on it can make it bad.
- The life of a release bearing can be damaged due to the manufacturing fault, driver driving with his foot resting on the clutch pedal, or a misadjusted clearance to make full action of the clutch ~ Paul Smith, experienced transmission technician (Working on cars, motorcycles)

Symptoms of bad throwout bearing:
If your vehicle’s throw out bearing can’t do its job correctly, then it means it has faced some problems. What are the symptoms of bad throwout bearing? Following are some of the most common symptoms of bad throwout bearing.
01. The change of noise:
The first and most common symptom of throw out bearing failure is its noise change.
If you find any strange manual transmission bearing noise, mainly when pushing the clutch, the throw-out bearing is in problem. You will hear strange noises when driving, especially in the transmission area.
02. Vibration of Clutch Pedal:
If you push down on the clutch pedal and feel a vibration on your foot, perhaps it happens because of a lousy throw-out bearing.
When the bearing can’t join to the pressure plate smoothly, vibration occurs. When braking or accelerating, you need to check different components, including axels, wheel bearings, and brakes if you feel a vibration.
If the problem becomes worse, you will feel excessive vibration. Nevertheless, you might not experience any vibration if the issue is just a beginning.
03. Problem in changing gears:
If you feel that it is tough to change gears in your manual transmission car, then it could be because of a bad clutch release bearing.
Often this sign is noticed in the last stages of the earlier symptom where you’ve a pressed clutch. If you can’t release the clutch accordingly, you accelerate the risk of stalling the car.
Stalling is too risky, mainly when you are in a traffic jam and your stalled car makes a blockage in the road.
If you find a problem in changing gears, you need to check some other components and ensure they don’t need any maintenance.
04. Stiff Clutch Pedal:
Another significant bad throw-out bearing symptom is the stiff clutch pedal. What do you mean by the stiff clutch pedal, and why does it occur?
Similar to any other part of the transmission system, special lubricating properties on the release bearing can keep it smooth for a long time.
Unluckily, due to the wear down of bearing, the lubricating properties also wear down, making the clutch pedal stiff to work.
Your car is useless with a stiff clutch pedal because changing/shifting the gear is tricky.
What does a bad throwout bearing sound like?
The bad throwout bearing sound isn’t normal, rather it’s a bit strange to hear. If you keep your ear and eye on the out, you may listen to the bad throwout bearing sound like,
- Whirling and
If the noise comes from the transmission system and under the hood, both driver and passenger will hear the loud noise. The throwout bearing noise will be more audible if you press your engine harder.
You can contact an automotive expert if you face such a problem.
How long can you drive with a bad throw out bearing?
Without a throw out bearing or release bearing, your vehicle’s engine will ruin and you can’t drive anymore. But still, there is a chance to go with a bad throw out bearing.
But how long can you drive with a bad throw out bearing?
The answer is, “it varies” because it depends on how bad it is. If you use it once per drive, you can go for quite a while, ~ Bradley Gilbert.
You might drive for years, mainly if you know how to shift the gear without clutch pedal~ Brian Good, Dirt Digger, Litigation Analyst.
I found a user who drove his Mustang for 10,000 miles on a chirping throw out bearing. With a groaning or chirping clutch release bearing, many people I found going fine on their 150,000 plus miles car (if the factory parts are original).
A noisy release bearing can last just 5 minutes or last for 5 years. Or you can drive with a noisy bearing for thousands of miles/sometimes years.
However, you can’t drive anymore if the throw out bearing fails completely.
How much to replace throw out bearing?
The throwout bearing replacement cost isn’t cheap. Technically, it’s a bit pricey process which depends on many factors including:
Transmission bearing replacement cost:
- Average economy car: $800 – $1,200.
- Average parts charge: $90 – $500.
- Labor cost: $350 – $700.
More specifically, on average, you need to spend between $400 to $1500 for the throw-out bearing replacement/clutch release bearing replacement (including all the variables).
But if you talk about the replacement cost of aftermarket bearing, then the charge will not be more than $10 to $30.
