The Comprehensive Guide to Installing Bearing Buddies

Introduction

Bearing buddies are crucial components for trailers, providing protection for wheel bearings and promoting their longevity. Improper installation can compromise the effectiveness of these devices, leading to costly repairs and reduced trailer performance. This comprehensive guide will equip you with the necessary knowledge and step-by-step instructions to ensure successful bearing buddy installation.

Understanding Bearing Buddies

Bearing buddies are small, cylindrical devices that house grease and an indicator flag. They are designed to automatically lubricate wheel bearings while keeping contaminants out. By maintaining proper lubrication, bearing buddies extend the life of bearings by 80%, resulting in reduced maintenance costs and increased trailer reliability.
