There's a slight knock on start up or even while driving. I have a 14 LT with 34.2K auto and I'm not sure if it's the turbo with possible shaft play or what. I have a 12 model LT and I hear nothing. I'm a little concerned about the noise and I need to get it in before my bumper2bumper expires.. Any input on this matter?

I service the vehicle myself in terms of oil and the simple stuff. It's been doing to for quite some time now and never thought twice about it until now. Car has ample power and doesn't lag. But definitely going to take it in hopefully this week!
