Because it was overused.
That is your clutch flywheel going, basically you need a whole new clutch system which is very expensive, the clicks will get more loud and more frequent
Yes you can. You need to replace the clutch when you realize its starting to go out. You will mess up with gears. When a clutch fails, it is usually due to a worn clutch disk or worn springs in the pressure plate. If you continue to drive the car with a worn disk, the rivets on the disk will eventually start to rub against the pressure plate or flywheel. You will then have to resurface the flywheel and replace the pressure plate. Before replacing a clutch, make sure it is adjusted properly, since an out of adjustment clutch will slip and act like it is worn out.
your clutch is going out. i had the same problem. look into getting a new pressure plate and while your at it, get a new flywheel. if you done look at it soon, you will be walking
When you let the clutch out all the way, if it continues to slip, it's worn out. A slipping clutch indicates that the clutch wear surface has gone. Plan on replacing the clutch disk, pressure plate, throwout bearing and have the flywheel resurfaced. While it's apart, it wouldn't be a bad idea to replace the clutch master and slave cylinders as well. If the clutch will not release when you press the pedal, it could be a warped clutch disk or pressure plate or a faulty hydraulic clutch system (master cylinder/slave cylinder).
If there is a clunking noise on a 1991 Firebird Formula 5.0 when going below 30 mph, and the clunking noise does not happen when the clutch is depressed, it is probably a problem with the flywheel. The flywheel moves freely when the clutch is depressed. When the clutch is not depressed, it could be that something is rubbing on the flywheel, like the clutch plate.
your clutch may be going bad
It is probably the throw out bearing going bad. You have to remove the transmission from the bottom to replace it. Replace the clutch, pilot bearing, and throw out bearing and have the flywheel resurfaced.
Your pressure plate and throw out bearing in your clutch assembly are worn out...time for a new clutch
No pressure in clutch resevior, its next to the brake resevior, if its empty, put more, if not you have a leak.
If this is a 2WD truck, it's one of the easiest and can easily be done by one person even without a hoist lift. If this is a 4WD truck, first remove the transfer case, then proceed as if it were 2WD. Remove the shifter linkages and whatnot and the rear driveshaft and the starter. Then, remove the transmission mount and transmission support frame crossmember. Remove the clutch housing (bellhousing) bolts and clutch linkage. Pull the transmission rearward and remove from the vehicle. Be happy it is such a lightweight unit. Unbolt the pressure plate from the flywheel and remove the pressure plate and clutch disc. Evaluate the condition of the flywheel and resurface or replace if needed. Replace the pilot bearing and lubricate all moving parts except for the clutch disc, flywheel, and pressure plate friction surfaces with a moly-based grease or engine assembly lubricant. Set the clutch disc and pressure plate in place, holding it there with the alignment tool included with the clutch kit. Thread all pressure plate bolts into place until just barely snug, then wiggle the alignment tool about until you're sure everything is centered. Torque the bolts tight at this time. Tightening these bolts somewhat beyond manufacturer's specification is not really going to hurt anything. Leaving them loose is bad. Reinstall all other parts that you removed in reverse order. Check and correct all fluid levels. Verify proper clutch operation.
The clutch slipped. Shouldn't be a problem. The higher the gear the less grab it has for lack of a better term. The motor is putting out more power than the transmission can use and it has to go somewhere. With a new clutch, the motor would probably die. With one that has some wear on it the surface is slick enough that it will slide between the flywheel and the pressure plate.
If you clutch and it either goes all the way in with no pressure there is a leak in your slave cylinder or the higher you have to clutch means your clutch is sliping and has to be replaced. If your doing a lot of power shifting i would suggest you get a racing clutch instead.
