Well, the gearbox has to come off. The bearing probably needs replacement rather than repair. Unless the clutch is very new, you may as well replace it too, and the pressure plate. Examine the throwout fork very closely for cracks, as they can fail that way.
Insert a pilot shaft or an old input shaft into the center of the clutch disc, pressure plate, and the pilot bearing in the crankshaft.
With the pilot tool supporting the clutch disc, loosen the pressure plate bolts gradually and in a crisscross pattern.
Remove the pressure plate and clutch disc.
Clean the transmission and clutch housing. Clean the flywheel surface with a non-oil based solvent. Wash your hands before installing or handling the clutch assembly parts. Hold the clutch disc by the center hub only.
Before assembly, slide the clutch disc up and down on the transmission input shaft to check for any binding. Remove any rough spots with crocus cloth and then lightly coat the shaft with Lubriplate.
To remove the throwout bearing assembly: Remove the return clip and take out the throwout bearing carrier and the bearing.
To replace the throwout arm use a / 16 in. punch, knock out the throwout shaft spring pin and remove the shaft, springs, and the center lever.
Do not immerse the throwout bearing in solvent; it is permanently lubricated. Blow and wipe it clean. Check the bearing for wear, deterioration, or burning. Replace the bearing if there is any question about its condition.
Check the shafts, lever, and springs for wear and defects. Replace them if necessary.
If you hadn't planned on replacing the clutch disc, examine it for the following before reusing it. Loose rivets. Burned facing. Oil or grease on the facing. Less than 0.3mm left between the rivet head and the top of the facing.
Check the pressure plate and replace it if any of the following conditions exist: Scored or excessively worn. Bent or distorted diaphragm spring. Loose rivets.
Insert the control lever into the clutch housing. Install the two return springs and the throwout shaft.
Lock the shift lever to the shaft with the spring pin.
Install the throwout bearing carrier and the bearing. Install the return clip.
Grease the carrier groove and inner surface.
Lightly grease the clutch disc splines.
The clutch is installed with the larger boss facing the transmission.
Support the clutch disc and pressure plate with the pilot tool.
Turn the pressure plate so that its balance mark aligns with the notch in the flywheel.
Install the pressure plate-to-flywheel bolts head-tight. Using a torque wrench and, working in a crisscross pattern, tighten the bolts to 11-15 ft. lbs.
Install the transmission or transaxle as outlined.
Adjust the clutch as described in the following information.
Do you have a hydraulic clutch (is there a clutch fluid reservoir)? Most cars made in the last 20 years are hydraulic. If so, there are no adjustments to be made, and it simply means the friction material on your clutch disc is worn out and the disc needs replaced. It's best to machine the pressure plate as well, or replace it. Most good clutch kits come with a clutch disc, pressure plate, and throwout bearing. The surface of the flywheel will need inspected as well to check for cracks or glazing. Having it machined is always a good idea while you're in there. It's a lengthy job to do at home, and an expensive one if taken to a shop. The labor and cost involved depends on the model of your vehicle.
The cutch pedal should have about an inch of free play before contacting the pressure plate. otherwise throw out bearing will run continuously . It wont last long. Adjust at firewall for 1 inch of free play at the top of pedal stroke.
A kit is usually around $200.00 us dollars for the pilot bushing, clutch, pressure plate. Assuming that the flywheel is good.
Labor can be between$300 to $500, but any garage should be able to quote you a labor time and cost.
It's going to involve removing the transmission. Your clutch and/or pressure plate maybe bad. You'll be better off to replace them also, especially if you have a lot of miles. Before this happened, did the clutch catch when you would let off the pedal a little way up?
First you go to mechanics school so you know the basics on safety etc.
Now you can block the car up in the air and remove the driveline and all electrical and mechanical connections from the transmission. Next support the engine while you unbolt the transmission from the engine. using your transmission jack slide the transmission back far enough to get easy access to the pressure plate. remove the bolts holding the pressure plate in place and remove the old clutch. Of course you got a new clutch, pressure plate and throwout bearing right? you may need a pocket bearing for the tip of the transmission input shaft as well. installing is the reverse of removing though you will have to consult the manual for torque specifications and you will need to make sure the clutch is centered before you bolt the pressure plate back down.
OR you could take it to a transmission shop and have them do it for a couple hundred bucks.,
Only option is to do a clutch job. it comes with all the parts and the throwout bearing. You could do just a throw out bearing but the labor cost will be the same as doing the whole clutch job.
YOU DONT
If your clutch pressure plate has a stuffed thrust bearing then you are riding the clutch pedal and the clutch is running all the time to burn out the bearing so the centre plate is 1/2 worn and pressure plate springs or toggles are getting week so the answer
is to replace both it will save doing the job in 2 months time (belive me)
