Embark on a Boat Trailer Bearing Odyssey: A Comprehensive Guide for Smooth Sailing

Introduction

The unwavering support of your boat trailer's bearings is essential for both its longevity and your peace of mind. However, like all mechanical components, bearings inevitably succumb to the relentless assault of time and wear. Replacing them is a crucial maintenance task that can extend the lifespan of your trailer and prevent unexpected breakdowns on the open road.

Why Replace Boat Trailer Bearings?

According to the National Trailer Dealers Association (NTDA), bearings account for 80% of trailer failures. This staggering statistic underscores the critical importance of replacing bearings before they become a liability.

Signs of Failing Bearings:

• Excessive heat or noise coming from the hubs
• Loose or wobbly wheels
• Visible cracks or pitting on the bearings
• Discoloration or flaking of the bearing grease
