Trailer Bearing Replacement: A Comprehensive Guide to Keeping Your Rig Rolling

Trailers are an essential part of many businesses and personal lives. They provide a convenient way to transport goods and equipment, but they can also be a source of headaches if they are not properly maintained. One of the most important maintenance tasks for a trailer is to replace the bearings.

Why Do Trailer Bearings Fail?

Trailer bearings fail for a variety of reasons, including:

• Overloading: When a trailer is overloaded, it puts excessive stress on the bearings. This can cause them to overheat and fail prematurely.
• Improper lubrication: Bearings need to be properly lubricated to function properly. If they are not lubricated, they can seize up and fail.
• Water contamination: Water can get into the bearings and cause them to rust. This can also lead to premature failure.
• Age: Bearings wear out over time. The average lifespan of a trailer bearing is 5-7 years.
