The Ultimate Guide to Installing Bearing Buddies: A Comprehensive Step-by-Step Manual

Introduction

Bearing buddies are indispensable devices that protect wheel bearings from contaminants, moisture, and corrosion. Installing them is crucial for extending the lifespan of your trailer's wheel bearings. This comprehensive guide will provide you with all the necessary knowledge and techniques to install bearing buddies correctly and effectively.

Materials Required

Before you begin, ensure you have the following materials:

• Bearing buddies specific to your trailer's axel
• Grease gun
• High-temperature bearing grease
• Clean rags
• Safety gloves

Step-by-Step Instructions

1. Safety First & Axle Preparation

• Park your trailer on a level surface and engage the parking brake.
• Remove the hubcap and dust cap from the wheel you wish to install the bearing buddy on.
• Inspect the wheel bearing for any signs of damage or wear. If necessary, replace the bearing.
• Clean the axle spindle thoroughly using a clean rag.

2. Install the Inner Seal

• Slide the inner seal over the axle spindle, ensuring it fits snugly against the bearing.
• Apply a thin bead of grease around the outer edge of the inner seal.

3. Install the Bearing Buddy Body

• Insert the bearing buddy body over the inner seal and slide it down until it rests against the hub flange.
• Tighten the bearing buddy body's bolts by hand until snug.

4. Fill with Grease

• Attach the grease gun to the bearing buddy's grease fitting.
• Pump grease into the bearing buddy until grease flows out of the purge hole.

5. Install the Outer Seal & Replace Dust Cap

• Slide the outer seal over the bearing buddy body, ensuring it fits snugly against the bearing.
• Apply a thin bead of grease around the outer lip of the outer seal.
• Replace the dust cap onto the wheel hub.

6. Tighten the Bearing Buddy

• Using a wrench, tighten the bearing buddy's bolts to the manufacturer's specifications.

7. Inspect and Repeat

• Inspect the bearing buddy for any leaks or damage.
• Repeat the process for the remaining wheels on your trailer.

Why Installing Bearing Buddies Matters

According to the National Trailer Dealers Association (NTDA), improperly maintained wheel bearings account for over 50% of trailer breakdowns. Bearing buddies effectively prevent:

• Contamination: Keeping dirt, debris, and moisture out of the bearings, reducing wear and tear.
• Corrosion: Blocking moisture and oxygen from reaching the bearings, preventing rust formation.
• Lubrication: Continuously delivering grease to the bearings, ensuring optimal lubrication.

Installing bearing buddies offers numerous benefits for your trailer:

• Extended Bearing Life: Protect bearings from premature failure, extending their lifespan.
• Improved Safety: Well-maintained wheel bearings reduce the risk of accidents due to wheel lock-ups.
• Reduced Maintenance Costs: Frequent bearing replacements can be costly. Bearing buddies minimize maintenance expenses.
• Increased Trailer Value: A well-maintained trailer with properly installed bearing buddies maintains its value.
