Yes and Yes. Depends on the tick you are referring to. A/C clutch, if you have the 4.6 3-V your will hear a tick from the valve lashers. Drive shaft is a 2-part with a joint in the middle, unlike pre S197 single unit. Design is prone to vibration due to small pinon angle changes +/-where the joint does not compensate adequately.
All in all, it is a Stang. It is the nature of the beast. After I listen for the "usual and customary souinds" Pennywise is cranked up and they all go away.
