My self I like the buddy's, I have not changer bearing in about 14 years. I like to use what is called a waterproof grease or one made for boat trailers and I also like to grease them before any trip over 10 miles like to Oneida or the finger Lakes. If theres water in them it will push it out. The trailer is over kill for a 16ft. boat . Now that I ran my mouth I better pull the wheels come spring.
