I can move the front drive shaft up and down at the transmission! on 2003 Mazda Tribute

What could be broke and what would be the name of the part?

Should move up and down some! Why are you checking, noise or what inspired you to look? Leaking fluid at that axle seal?
I agree with wetry need more info
had a vibration with a clanking noise and the faster it got the worse the vibration and did some research and found that it is the front drive shaft cv joint!I appreciate yall trying to help.
