I have been having problems with the Toyota Rav 4 for quite some time, because it was sounding, which I initially suspected as a noise of a defective exhaust but did not materialize. To the info: There is no noise in the stand, but when driving off these sounds start. From about 2500 rpm these sounds slowly stop again. I myself tap on a defective clutch. What does your experience say about this? Here is a proof video:http://www.youtube.com/watch?v=PCW7hgz80zk&feature=youtu .be
