Why do boat trailer wheel bearings fail so often?

Because the hubs get submerged — often in salt water — which washes out grease and lets water in, destroying the bearings. Regular repacking, bearing protectors, and inspecting before long trips prevent the seized-wheel failures that are the most common trailer breakdown.

Should I use bunks or rollers on my boat trailer?

Bunks cradle the hull along carpeted boards and support it well for storage and travel; rollers make launching and loading easier, especially solo or on shallow ramps. The best choice depends on your boat’s hull, your ramp, and how you launch — many trailers combine both.

What trailer lights hold up best for boats?

Submersible LED trailer lights are the most durable choice. They tolerate repeated dunking far better than incandescent bulbs, last longer, and light instantly. Sealed, waterproof connectors and a good ground are just as important as the lights themselves for reliability.
