My treadmill has become very noisy. This happened on sunday when i was using it. It has become so noisy (exteremely loud) that i can no longer use it. I have tried lubricating it but that hasn't helped. It has also strated stopping while in use. It is a rebok treadmill. Can anyone help?

Your rear roller bearing has gone. You need to replace it (obviously ) . Look on the net , if it is a common model this should be no problem . You can do it yourself easily so do not pay someone else to do it.
