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?
