You may need to pull it and replace that release bearing.I have had to do that once or twice in my life. It is not uncommon to have a defective bearing in a clutch kit. If you do go that far, have a look at the fingers on the presser plate.make sure that they are all compressed evenly. If any number of them are not the same height then the pressure plate is a problem. So, a couple of things to look for. Hope this helps
