as soon as i hit 80+ km/h what sounds like my front left wheel is making a knocking sound, the knock doesnt speed up or slow down it is just constant, sometimes it will be, knock knock knock or knock...knock....knock, as soon as i slow down it goes away, oh and this knocking sound happens about 75% of the time, sometimes there is no knocking. im thinking cv axle but before i go tearing stuff apart i'd like some other input...

thanks, reidzap.
