I've found several threads on various knocks up front and so far none of them have been the fix for me. It sounds like what a loose sway bar would sound like, but no joy. What I think I found is the front drive shaft has some play in it. When pushed forward it makes a knock sound that may be what I'm hearing from inside. I have seen drive shafts that have play but never one that actually knocks when hitting the end of play. Is the play normal and if so should it make noise when moving? Maybe spline joint has issues? TIA
