Well on one side of my trailer the rubber cap or cover has a rip or tear in it. Its leaking grease to the outer part of the rim. Can I just easily fix this with a new cap/cover?

And do you guys think the bearing is still good? Its been in the water a few times since I notced it so there is probably water in there?

This is my first boat and have never dealt with a trailer bearing before. And this is for a 2000 nitro nx882.

Would I just be able to go to a marina to pick up a replacement cover? And last question.

How do I remove the whole cap? Do I need to take off the rim and brakes or can I just slide the cover off?
