I got a 91 tt and I hear a clicking sound coming from the driver rear wheel that gets a little louder when brakes r applied, the sound follows wheel rotation. Also there is a knocking sound coming from the drivers side of the engine. That sound is heard when the engine is cold and u raise the trottle, but the sound either goes away or gets faint because u can't hear it after u get the revs up. The knocking sound is also heard when u start out in first and load the engine and start to go forward, it then goes away once it revs up. I don't think it's a knock sensor issue bit I could b wrong. Does anyone have any ideas what could b causing these sounds.
