How to fix PS4 Disc Drive Crunching Noises when inserting and removing games

In this video I show you how I tried to help someone on YouTube. The video is quick so you will have to pause it in order to read what was actually communicated. Terrible I know...
The noises here are created by the manual disc eject mechanism. Usually its the spring that is caught up in the gears. If the spring is gone the spindle gear rests on the intake gears and will inappropriately rub on them as they turn to intake/ eject a disc. Eventually teeth will break off.

Although we solved the issue of crunching noises, due to the complicated nature of working on PS4 disc drives Tyler received more issues for his efforts. Now his games won't read.
I still have an open invitation for Tyler to try and get his games to read again. Although his console is "about done" - I feel he still has some time with it and I am optimistic that we can get it reading again.
Let this be a lesson for all. Before diving into something, make sure you have done enough research so you are familiar with how the thing works. Even so, It is still possible to break things beyond repair.
