Buddy Bearings for Trailers: The Ultimate Guide to Keeping Your Rig Rolling

Introduction

Buddy bearings, also known as wheel bearings, are essential components of any trailer's suspension system. They allow the wheels to rotate smoothly and freely, while also supporting the weight of the trailer. Without properly functioning buddy bearings, your trailer will be unsafe and difficult to maneuver.

What Are Buddy Bearings?

Buddy bearings are typically made of two tapered roller bearings that are mounted back-to-back. The inner races of the bearings are pressed onto the trailer axle, while the outer races are held in place by a bearing hub. The bearing hub is then bolted to the trailer wheel.

When to Replace Buddy Bearings

Buddy bearings should be inspected regularly and replaced when they show signs of wear or damage. Some of the most common signs that buddy bearings need to be replaced include:

• Loose or wobbly wheels
• Grinding or squealing noises coming from the wheels
• Increased resistance when turning the wheels
• Visible cracks or damage to the bearings or bearing races

How to Replace Buddy Bearings

Replacing buddy bearings is a relatively straightforward process, but it is important to follow the manufacturer's instructions carefully. Here are the general steps involved:

1. Safety first: Park the trailer on a level surface and engage the parking brake.
2. Remove the wheel: Use a lug wrench to loosen the lug nuts on the wheel that needs the bearings replaced. Remove the lug nuts and carefully lift off the wheel.
3. Remove the bearing hub: Use a socket wrench to remove the bolts that hold the bearing hub in place. Carefully remove the bearing hub.
4. Remove the old bearings: Use a bearing puller to remove the old bearings from the axle and bearing hub.
5. Install the new bearings: Use a bearing press to install the new bearings onto the axle and bearing hub.
6. Reinstall the bearing hub: Place the bearing hub back onto the axle and secure it with the bolts. Tighten the bolts to the manufacturer's specifications.
7. Reinstall the wheel: Carefully lift the wheel back onto the axle and secure it with the lug nuts. Tighten the lug nuts to the manufacturer's specifications.

Troubleshooting Buddy Bearing Problems

If you are experiencing problems with your trailer's buddy bearings, there are a few things you can do to troubleshoot the issue:

• Check the wheel bearings: The most common cause of buddy bearing problems is worn or damaged bearings. Inspect the bearings for any signs of wear or damage, and replace them if necessary.
• Check the bearing races: The bearing races are the surfaces on the axle and bearing hub that the bearings ride on. Inspect the bearing races for any signs of wear or damage, and replace them if necessary.
• Check the bearing hub: The bearing hub is the part that holds the bearings in place. Inspect the bearing hub for any signs of wear or damage, and replace it if necessary.
• Check the axle: The axle is the part that the wheels are mounted on. Inspect the axle for any signs of wear or damage, and replace it if necessary.

Tips and Tricks for Maintaining Buddy Bearings

Here are a few tips and tricks for maintaining your trailer's buddy bearings:

• Inspect the bearings regularly: Inspect the bearings for any signs of wear or damage every time you service your trailer.
• Lubricate the bearings: Lubricate the bearings with a high-quality bearing grease every time you service your trailer.
• Keep the bearings clean: Keep the bearings clean by removing any dirt or debris that may build up on them.
• Avoid overloading the trailer: Overloading the trailer can put excessive stress on the buddy bearings, causing them to wear out prematurely.
• Have the bearings professionally inspected: If you are not comfortable inspecting or replacing the bearings yourself, have them professionally inspected by a qualified mechanic.
