My release bearing is making a squealing noise while running in neutral. The noise goes away completely when the clutch is pressed to the floor. What is causing this? My flywheel, clutch, pilot bearing and release bearing are brand new. I tried adjusting the clutch cable but the noise only goes away when the clutch is pressed to the floor. To add to this the car shakes badly when i take off in 1st gear & reverse. What is wrong ??????
