Screen wobbles back and forth when open

My 2015 Retina MacBook screen wobbles back and forth when I have the laptop open. There is nothing wrong with the display, it’s the half of the laptop that opens up on the hinge. When it opens, the lid will fall half an inch forward or back depending on the angle it is at. It makes a little squeaking sound as well when it moves. Again - nothing is wrong with the actual display/picture of the laptop. It is the actual metal part, if that makes sense. Sorry about the bad description.

Ideas on how to fix this? Anyone else have the same problem?
