My clutch makes a shity noise when pressed. I found out that it was the throw out bearing. I just ordered a brand new sachs clutch from a power seller on e-bay for 170 including shiping. First question am I stupid for getting it off e-bay? Second I wanted to install it myself however I found out from a manual that you need to take of the trany to get to the clutch. Is this a proffesionals only job or a good diy project.
