Eric, I just replaced my clutch system about 2 months ago, 51,000 miles. Even though you can shift with the throw out bearing squeeling and it will created a more friction and force on the system, You may have worn the disk down to the point it has now worn or groved into the flywheel. If this has done then you will have to remove the flywheel and have it turned also. If you will look at my web site www.specialtauto.com under drive train, I am showing what the disk and pressure plate look like as well as the clutch disk. Yes, I replace all the clutch parts when you have it tore down, it would be going out more than likley with in a few thousand miles unless you plan not to keep the car. It would also save a lot of money and time in the future. John hervey www.specialtauto.com/drive train
