So I am back here.

But right after, I set the bearing cover to the opposite position, the gearing contact is smooth and flowing. Any ideas on this? Have a great week ahead. Cheers!

It is less about the the height of the diff and more about the gear mesh. I run mine one notch looser than the instructions also. Much better gear mesh, much smoother drive line.
