2004 Ford Excursion clicking noise

If that's a single metallic click once each time you shift into reverse or drive, the two most common causes are a worn universal joint or a broken engine mount.

Thank you for the input!
It does it when I first start it in the morning
And then when I put it into drive or reverse only
The clicking sound only last for a few seconds .
But it comes and goes and when I give it gas it will click then goes away

My vote is for a universal joint. Sometimes they're really easy to identify. Sometimes they can be a little tricky because with just hand pressure there may not be enough movement to see. Another clue is if you see a ring of rust-colored powder around one of the cups.
