Sealed rear end???

Can anyone tell me if the rear end diff and axles are sealed? For example, when I back my boat in to launch, or recover, do I need to worry about water getting into my diff and ruining my diff oil? Thanks

No need to worry about your diff, you're good.

There isnt a vent tube in the rear diff, only the front.

My truck also has a vent tube on the rear. I just looked at it last weekend when i was installing my airbags. I have seen a lot of trucks go bogging into deeper water and never had issues with water in the rear end. I launch my boat in a lot of different launches, some shallow, some deep. I have never had an issue.
