Install Bearing Buddy: A Comprehensive Guide for Optimal Trailer Performance

Introduction
Properly installing bearing buddies is crucial for the longevity and safety of your trailer. Bearing buddies are essential devices that protect the wheel bearings from water, dirt, and other contaminants, preventing premature wear and costly repairs. In this article, we will explore the benefits of installing bearing buddies, provide step-by-step instructions, and discuss common mistakes to avoid.

Benefits of Installing Bearing Buddies

1. Extended Bearing Life
Bearing buddies create a seal around the wheel bearings, preventing water and dirt from entering. This significantly extends the life of the bearings, reducing the need for frequent repairs or replacements. According to the National Highway Traffic Safety Administration (NHTSA), proper bearing maintenance can increase bearing life by up to 50%.

2. Improved Safety
Wheel bearing failure is a serious hazard that can lead to accidents. Bearing buddies prevent bearing failure by keeping the bearings lubricated and free of contamination. The Federal Motor Carrier Safety Administration (FMCSA) reports that bearing failure accounts for over 10% of all trailer accidents.

3. Reduced Maintenance Costs
Properly installed bearing buddies reduce the need for maintenance and repairs. By preventing bearing failure, you save on costly labor and parts. The American Trucking Associations (ATA) estimates that bearing buddies can save fleets up to $1,000 per trailer per year in maintenance costs.

How to Install Bearing Buddies

1. Gather Materials
- Bearing buddies
- Grease gun
- Grease cartridge
- Rags or gloves

2. Preparation
- Remove the old bearing buddies (if any).
- Clean the spindle and the hub thoroughly.
- Apply a small amount of grease to the spindle.

3. Installing the Bearing Buddies
- Insert the bearing buddies into the spindle.
- Hand-tighten the bearing buddies until they are snug against the hub.
- Use a wrench to further tighten the bearing buddies, but do not overtighten.

4. Lubrication
- Pump grease into the bearing buddies until grease starts to come out the back.
- Wipe away excess grease.

Common Mistakes to Avoid

1. Overtightening the Bearing Buddies: This can damage the bearing buddies or the spindle.
2. Undertightening the Bearing Buddies: This can cause the bearing buddies to leak grease.
3. Not Lubricating the Bearing Buddies Regularly: This can lead to bearing failure.
4. Using the Wrong Grease: Always use a grease specifically designed for bearing buddies.
5. Installing the Bearing Buddies Incorrectly: This can prevent them from functioning properly.
