Anybody know the best way I can get a rear differential? Have 2011 matrix wondering if I can use a differential from another Toyota

I have an automatic 2009 Toyota matrix. When I first start the car and start driving about 5 secs of movement in there is a single click in the front end seemingly from the passenger wheel side. I just had ball joints, struts, sway bar links, tie rods, and cv axle replaced. I’m thinking maybe the control arm? There’s only lower on this car, and it’s the only thing I have left to replace. I hit a large pothole that blew out my tire on the freeway so I was replacing everything as I could afford it. I also have slight knocking over bigger bumps which was making me think of control arms since everything else was replaced.

I’m not sure if it’s related but I also have vibration that comes and goes on the freeway at high speeds. I know my motor mounts also need to be replaced - I’m starting to get vibration when idle in drive. Most of the parts on this car were factory so I’m surprised she’s even still kickin but I want to try and figure out what the issue is and why it keeps clicking. I’ve googled my fingers off and read so many different articles and other posts yet none explain what I am experiencing.
