The symptoms of a bad throw out bearing include grinding and rattling noises when shifting, grinding gears when shifting, noise from the clutch pedal, vibration, gear shift issues and issues with the clutch.
Or if the transmission does not shift at all then your throw out bearing or clutch could be bad.
Throwout bearing noise is nose that the throwout bearing makes when it's worn down or going bad.
Throwout bearigns can make a grinding or rattling noise when pressing down on the clutch which can indicate the throwout bearing is bad and needs replaced.
A throw out bearing is a type of bearing that is used for temporarily disengaging the vehicle engine from the transmission during gear shifting in manual transmissions.
When you press the clutch pedal in the throw out bearing gets closer to the flywheel which in turn drives the release fingers of the pressure plates towards the inside.
This allows you to shift the transmission while the engine is running.
When you release the clutch pedal then the clutch comes back into contact to drive the transmission and propel the vehicle.
The “bearing” part comes into play because the outside of the throwout bearing is stationary while the face rotates with the pressure plate and its fingers; this occurs any time the clutch pedal is depressed.
While a slightly damaged release bearing usually causes a whining noise, a severely damaged release bearing often produces loud, grinding noises when it is placed under pressure.
At some point, the fit and finish will no longer fit into the assembly properly, causing the clutch to eventually fail if the release bearing isn't replaced.
If the bearing is worn, the clutch will slip and you won't be able to shift between gears.
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.
Every issue with the throw-out bearing will eventually result in some form of problem shifting gears.
If it begins to feel like your clutch is no longer fully engaging, that's because it isn't.
This will make it increasingly difficult for gears to shift.
Here are some clutch failure red flags: Your clutch feels spongy, sticks or vibrates when you press it.
You hear a squeaking or a grumbling noise when you press down on the pedal.
The average cost for a throwout bearing replacement is $30.00 to $820.00, depending on if you take it to the mechanic or DIY.
The price range listed is based on the national average for all vehicles and does not consider taxes, fees, or your vehicle's particular make, model, or location.
