Reduced Downtime: By preventing premature bearing failure, repacking minimizes downtime and keeps your trailers on the road.

Improved Fuel Efficiency: Well-maintained bearings reduce friction, leading to improved fuel efficiency of up to 5%. (Source: U.S. Department of Transportation)

Reduced Maintenance Costs: Repacking bearings proactively prevents costly repairs and replacements.

Effective Strategies for Repacking Trailer Bearings:

Use High-Quality Grease: Invest in premium lithium-based grease specifically designed for trailer bearings.

Apply Grease Liberally: Pack bearings generously to ensure proper lubrication.

Tighten Hub Nut Correctly: Overtightening or undertightening the hub nut can damage bearings.

Regular Inspections: Schedule regular inspections to monitor bearing condition and grease levels.

Common Mistakes to Avoid:

Using the Wrong Grease: Avoid using general-purpose greases that may not provide adequate lubrication.

Overpacking Bearings: Excess grease can cause overheating and premature bearing failure.

Skipping Grease Inspections: Regularly check grease levels and replace as needed.

Ignoring Seals: Damaged seals allow grease to escape and contaminants to enter, shortening bearing life.

Step-by-Step Guide to Repacking Trailer Bearings:

Safety First: Park the trailer securely, chock the wheels, and wear safety glasses.

Remove Hubcap and Bearing Cover: Use a hammer and chisel to remove the hubcap and expose the bearing cover.

Remove Old Grease and Bearings: Remove the old grease and bearings carefully, using a grease gun and bearing puller.

Clean Hub and Bearings: Clean the hub and bearings thoroughly with degreaser.

Apply New Grease and Bearings: Pack new grease into the hub and install the new bearings.

Tighten Hub Nut and Reassemble: Torque the hub nut to the manufacturer's specifications and reassemble the hub.

Success Stories:
