Breathers for the winter

Do many people here have breather tubes permanently attatched to their axles etc.? I was wondering becouse it's always flooding around here at this time of year and I also end up in a lot of mud baths. It's the really nasty,clay mud thats slippery. You only have to park a 2 wheel drive on what seems a normal patch of grass and you can get stuck becouse of the permanent layer of water on it.
I just had a rear axle replaced and it had a bit of water in it apparently. I've only done a bit of tame green laning and gone through some shallow fords that non 4x4's have managed to cross.
Is it better to permanently fit breather tubes for this sort of ****ty weather?

my 1989 defender has breather tubes from both axles that run up to and fasten to the bulkhead just under the bonnet.

My Disco has them on both axles and on g&t boxes, and all go up to the bulkhead under the bonnet, just like vivnaps defender.

Yours might have them, but they could be blocked or dropped, if you're getting water in it's a good idea to fit some, or get the ones that are fitted checked and cleaned out. Simplest way is to remove the piping and blow it out with an airline, then remove the fitting and do likewise ... easy peasy, just fiddly ...
