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.
- Toyota Part #90404-51026 (Camry Union Piece for Rear Diff)
- Specter Filters (Autozone/Advance Auto)
- 1/4" Fuel Line (little less than 15') and some hose clamps
- 1/8 x 1/4 x 1/4 'T' Barb Connector
- 3/8" x 1/4" Barb Connector
If you got an e-locker breather, your gonna need another 'T' to tie in the rear breather. I don't have one, so I can't give the info on that.
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.
2ND UPDATE: 15k on this breather setup. Fluids still look like new. Filters look very clean too.
I also made a box out of a 4 gang electrical box from Lowes and used the breathers that Shadow-Warrior recommended (specter).
