I've never been real good at justifying not doing something based on a doubt, I understand and see your train of thought on it though

However I have flooded and subsequently ruined an axle or three over the years and had to replace/rebuild them due to 1- submersion, 2- bad seals, 3- poor line maintenance or 4- breathers being too low

I end up in water anywhere from above hub level to half way up my grill at least two dozen times a year just to get home or get to work on an emergency call, haven't had any water in my axles/trans so far, so I'm pretty happy with the 10-15 dollar insurance plan even if it does absolutely nothing, because if I did nothing and the method did happen to help..

I'd be pretty upset at myself with having not done it
