This is where the bearing buddy comes in to play...

Driving down the road your hubs get warm building pressure..
When you back into the water this rapidly cools the hub which lowers the pressure actually pulling a vacuum causing water to be sucked into the hub.

The bearing buddy has a spring and piston, as you pump grease it pushes the piston compressing the spring.
There is always pressure in the hub so no water can be sucked in.

My bearings are roughly 20 years old and get greased once a year.
They have some wear but nothing the grease doesn't take up.
Prolly due for some new ones but... If it ain't broke don't fix it..
