Im looking for a mod to remove the sheath sound when scrolling through sheathed weapons.

This is what, your 40th new thread in two weeks?
This one http://www.gamesas.com/topic/1487212-help-me-morrowind-mods-forum-youre-my-only-hope/ has the fitting name for you and your problems, why you make another thread 7 MINUTES later??

For your question: Not existent because not possible.
