How often should trailer bearings be repacked with grease?

Repacking trailer bearings with grease at least once a year or after a specific mileage is essential for maintaining the longevity and performance of the trailer. This practice helps ensure that the bearings are properly lubricated, reducing friction and wear. Regular maintenance prevents the possibility of bearing failure, which can lead to significant safety issues and costly repairs.

The recommendation to follow a time frame or mileage interval responds to varying conditions that trailers may be subjected to, such as load weight, road conditions, and frequency of use. For example, trailers that are used more frequently or under harsher conditions may require more frequent maintenance beyond the annual schedule.

Certain factors may influence the frequency of this maintenance, but generally, an annual service or mileage-based schedule is a good industry standard to prevent problems before they arise.
