Repacking Trailer Bearings: A Comprehensive Guide to Proper Maintenance

Introduction

Trailer bearings are a critical component of your trailer's safety and performance. They play a vital role in reducing friction and heat, preventing premature wear, and ensuring smooth operation. Proper repacking of trailer bearings is essential to extend their lifespan and maintain the reliability of your trailer.

Why Repacking Trailer Bearings Matters

• Extended Bearing Life: Regular repacking replenishes the lubricant and removes contaminants, reducing wear and tear and extending the bearing lifespan.
