Our team of experts has compiled this comprehensive guide to help you master the art of repacking trailer bearings and keep your trailer running like new.

Effective Strategies, Tips and Tricks

Use premium-quality bearing grease: Invest in a high-temperature bearing grease specifically designed for trailer bearings.

Pack the bearings tightly: Fill the bearing cups and races to capacity to prevent premature wear.

Inspect the seals: Replace worn or damaged seals to prevent grease contamination.

Use a torque wrench: Follow the manufacturer's recommended torque specifications to avoid over- or under-tightening the axle nuts.

Monitor bearing temperature: Regularly check the bearing temperature using an infrared thermometer to detect any potential issues.

Lubricate moving parts: Apply grease to the brake shoes, slides, and other moving parts to reduce friction and wear.

Common Mistakes to Avoid

Skipping regular inspections: Neglecting to inspect and repack your bearings can lead to costly repairs.

Using improper grease: Using the wrong type of grease can compromise bearing performance and shorten their lifespan.

Over- or under-tightening the axle nuts: Improper torque can damage the bearings or cause axle failure.

Ignoring damaged seals: Allowing grease to leak out can cause contamination and premature bearing failure.

Neglecting brake shoe lubrication: Dry brake shoes can cause excessive wear and reduce braking effectiveness.

Mistake	Consequence
Skipping regular inspections	Costly repairs
Using improper grease	Compromised bearing performance and shortened lifespan
Over- or under-tightening the axle nuts	Bearing damage or axle failure
Ignoring damaged seals	Grease contamination and premature bearing failure
Neglecting brake shoe lubrication	Excessive wear and reduced braking effectiveness

Getting Started with Repacking Trailer Bearings

Gather necessary tools and materials: Collect a torque wrench, bearing grease, new seals (if needed), rags, and a grease gun.

Prepare the trailer: Park the trailer on a level surface and chock the wheels.

Raise the trailer: Use a jack or jack stands to raise the trailer and provide access to the bearings.

Remove the hub assembly: Unbolt the hub assembly from the axle and carefully remove it.

Clean the bearings and components: Thoroughly clean the old grease and dirt from the bearings, races, and hub assembly.

Inspect the bearings and seals: Check for any damage or wear and replace them if necessary.

Pack the bearings: Fill the bearing cups and races with fresh bearing grease.

Reinstall the hub assembly: Carefully align and reinstall the hub assembly onto the axle.

Tighten the axle nuts: Use a torque wrench to tighten the axle nuts to the manufacturer's specifications.

Lubricate moving parts: Apply grease to the brake shoes, slides, and other moving parts.
