I did my own version of the scuba breather mod based on these:
Big thanks to both for locations and ideas.
I ran the rear differential and transmission breathers up to the engine bay right behind the battery and extended the two breathers that were already relocated up there just a little further. Does anyone know what breathers they are? EDIT: ADD and Front Diff... Thanks maxamillion2345
UPDATE: Before this mod, my diff oil had water in them after about 5k miles (or one hunting season). I just had a chance to check the fluid after this mod and it came out clean. I think another oil change after this hunting season will be enough evidence for me.
I also made a box out of a 4 gang electrical box from Lowes and used the breathers that Shadow-Warrior recommended (specter).
