to extend Breather tubes or not?

[SeaCelt]

I have a 2021 JLU Willys and am wondering if it is wise to extend the diff/trans/transfer case breather tubes, or if the factory breather valves are sufficient to keep the water and debri at bay?

How deep of water are you consistently driving through?

They have a one way valve, I would be too worried.

I extended mine up higher in front, a lift makes it “shorter”. Also in the rear, I can’t remember if I went all the way to the engine bay or up into the rear taillight.

Well, the factory setup is pretty good for 30” and you have a lift and larger tires. That should put you at roughly 36” of water depth before you’ve exceeded what Jeep says you can cross. Change/check your diff oil after a few crossings and see if there is any water in there.

reasonable approach and thank you.
