So if you’re looking for an easy way to prolong the life of your trailer bearings, then consider investing in a set of Bearing Buddies. Your trailer will thank you for it!

How to Install Bearing Buddies on a Trailer

If you’re looking to install bearing buddies on your trailer, there are a few things you need to know. First, what are bearing buddies? They’re basically just an extra set of bearings that sit on top of your existing ones.

This gives your trailer wheels a little more support and helps keep them from wobbling around too much. Now that you know what they are, it’s time to learn how to install them. The first thing you’ll need to do is remove the old bearings from your trailer wheels.

To do this, you’ll need a bearing puller (available at most auto parts stores). With the old bearings removed, clean out any dirt or debris from the wheel wells. Next, take a look at the new bearing buddies and make sure they’re the same size as the old ones.

If not, they won’t fit properly and could cause damage to your trailer wheels. Once you’ve confirmed that they’re the same size, go ahead and slide them into place. Finally, replace the axle nuts and tighten everything down.

That’s it! You’ve now successfully installed bearing buddies on your trailer.

How Do Bearing Buddies Work

If you own a boat, then you’re probably familiar with the term “bearing buddies.” But what are they, and how do they work? Bearing buddies are devices that are installed on boat trailers to help keep the bearings lubricated.

They work by measuring the amount of grease in the bearing housing and adding more if needed. This helps to prevent bearings from overheating and failing. There are two main types of bearing buddies: automatic and manual.

Automatic units have a sensor that monitors the level of grease in the housing and adds more when needed. Manual units require you to check the grease level periodically and add more as necessary. Installing bearing buddies is relatively simple.

First, remove the old dust caps from your trailer’s bearings. Next, clean out any old grease or debris from the housing using a brush or compressed air. Finally, insert the bearing buddy into the housing and replace the dust cap.

Once installed, simply check your bearing buddy’s instructions to see how often it needs to be checked or serviced. With proper care, your bearings should last for many years to come!

Bearing Buddy Sizes

Bearing Buddy Sizes – Determining the Right Size for Your Trailer When shopping for Bearing Buddies, it is important to know the correct size for your trailer. The most common sizes are 12″, 14″, and 16″.

However, there are other sizes available as well. To determine the right size for your trailer, you will need to know the inner diameter (ID) of your wheel hub. This can usually be found in your owner’s manual or on a placard on the trailer itself.

Once you have this measurement, simply match it up with the corresponding Bearing Buddy size listed below. Inner Diameter Bearing Buddy Size 2-3/4″ 12″

3-1/4″ 14″

How to Grease Bearing Buddies

If your trailer has Bearing Buddies, then you know how important it is to keep them greased. Not only does this help protect your bearings from wear and tear, but it also helps keep them running smoothly. Here are a few tips on how to grease your Bearing Buddies:

1. Start by making sure that your Bearing Buddies are clean. If they are not, then you run the risk of contaminating the grease. You can clean them with soap and water or Brakleen.

2. Once they are clean, apply a generous amount of grease to each one. You want to make sure that the entire surface is covered. 3. Use a hand pump or power washer to force the grease into the bearings.

Be careful not to overdo it, as too much pressure can damage the seals. 4. Wipe off any excess grease and you’re done!
