Ultimate Guide to Replace Bearings on Trailer

Replace bearings on trailer is a crucial task for ensuring the safety and longevity of your trailer. By following our comprehensive guide, you'll gain the knowledge and expertise to tackle this project like a pro.

Impact of Neglected Trailer Bearings

Neglecting to replace bearings on trailer can have dire consequences. According to the Trailer Manufacturers Association, over 50% of trailer breakdowns are caused by bearing failure. This can result in:

Reduced fuel efficiency: Worn bearings increase friction, leading to higher fuel consumption.

Increased safety risks: Faulty bearings can cause wheels to lock up, resulting in accidents.

Extensive repairs: Neglecting bearing maintenance can escalate into costly repairs or even trailer replacement.

Steps for Replacing Trailer Bearings

1. Safety First

Engage the trailer's parking brake.

Chock the wheels on the opposite side of the bearing being replaced.

Use jack stands for additional stability.

2. Remove the Wheel and Hub

Loosen the lug nuts but do not remove them completely.

Use a hydraulic jack to raise the trailer slightly.

Remove the lug nuts and pull the wheel off.

Use a hub puller to separate the hub from the axle.

3. Inspect and Replace Bearings

Inspect the bearings and races for any damage or wear.

Carefully remove the old bearings.

Install new bearings in the races.

Apply grease generously to the bearings and races.

4. Reassemble the Hub and Wheel

Reinstall the hub onto the axle.

Place the wheel on the hub and tighten the lug nuts.

Lower the trailer and torque the lug nuts to manufacturer specifications.
