Been hearing a kind of "knocking" sound. Sounds like it's coming from the front left. I hear it when I start to accelerate slowly from a stop or if I am slowing to a stop. Pretty much when the car jerks the most forward or backward.<p>Has there ever been any "shock knock" issues with the '05 R's? Or my other thought is maybe a bad axle. Any help is appreciated.<p>also, do I have to have it looked at by the dealer I bought it from or can I take it to a closer dealer. It is still under warranty with only 53xx miles on it and only 6 months old.<p>really need to get this fixed before June since it will go out for its first track outing in St. Louis at GIR.
