There are lots of things in this forum covering maintainence items for first time owners to look at. Mainly in the drive line concerning the transmission and AWD system.
As far as the clicking in your front end, it's super common and due to a badly made washer from Ford. They did end up creating a fixed version but IMO I never changed mine and the clicking went away. The issue isn't mechanically dangerous afaik.
Welcome to the forums tho!
