20 Oct 2024

Are your trailer wheel bearings protected? Water intrusion is a common enemy of trailer bearings, leading to corrosion, premature wear, and costly repairs. This guide provides a comprehensive overview of how to install Bearing Buddies, a popular solution for keeping water out and ensuring smooth, trouble-free towing. By following these steps, you can safeguard your investment and enjoy countless miles on the road.

Bearing Buddy installation isn't rocket science, but doing it correctly is crucial for optimal performance. We'll cover everything from preparing your trailer hub to the final checks, empowering you with the knowledge to tackle this task with confidence. Whether you're a seasoned DIY enthusiast or a beginner, this guide offers valuable insights and practical tips for successful Bearing Buddy installation.

Bearing protectors, often called Bearing Buddies, became popular in the late 20th century as a solution to the pervasive problem of water damage to trailer wheel bearings, particularly in boat trailers frequently submerged. Prior to their widespread use, frequent repacking and replacement of bearings were common due to corrosion from water entering the hub during launching and retrieval. The introduction of Bearing Buddies significantly reduced this issue by creating a sealed barrier against water intrusion.

The key principle behind Bearing Buddies and similar protectors is the creation of positive pressure within the hub. By filling the hub with grease and then installing the Bearing Buddy, a spring-loaded piston creates a seal against the spindle and pressurizes the grease. This pressure prevents water from entering the hub, even when submerged. Correct installation is vital to achieve this seal and maintain the pressure, preventing bearing failure and costly repairs.

Proper Bearing Buddy installation ensures the longevity of your wheel bearings, saving you time and money in the long run. A correctly installed Bearing Buddy creates a barrier against water and contaminants, significantly reducing the frequency of bearing repacking and replacement. This translates to fewer maintenance headaches and more time enjoying your trailer on the road or on the water. Beyond cost savings, proper installation also contributes to safer towing by preventing bearing failure, which can lead to wheel detachment and potentially dangerous accidents.

Three key benefits of properly fitting Bearing Buddies include extended bearing life, reduced maintenance, and improved towing safety. For example, a boat trailer owner who regularly launches and retrieves their boat in saltwater can significantly extend the life of their wheel bearings by installing Bearing Buddies, protecting them from the corrosive effects of saltwater. This also means less frequent repacking, freeing up time for more enjoyable activities. Additionally, preventing bearing failure through proper Bearing Buddy installation ensures safer towing, reducing the risk of accidents caused by wheel detachment.

Action Plan for Installing Bearing Buddies:

1. Gather Supplies: Bearing Buddies, grease, grease gun, wrench, rags.

2. Prepare the Hub: Clean and inspect the hub and bearings. Remove old grease and inspect for damage.

3. Pack the Hub with Grease: Thoroughly fill the hub with grease using a grease gun.

4. Install the Bearing Buddy: Press the Bearing Buddy firmly onto the hub, ensuring a proper seal.

5. Check for Proper Installation: Verify the Bearing Buddy is securely attached and the zerk fitting is accessible.
