An automatic pressure-relief feature is built into the Bearing Buddy. When the device is full, grease will seep around the edges of the piston and into the barrel. This prevents overfilling that can damage the inner seal.You can manually check the grease level in your Bearing Buddy by pressing on the edge of the piston. If you can rock or move the piston, the hub is properly filled.

If you will remove the wheel on your trailer and pull your wheel bearings and get the outer wheel bearing part number that would help you with which Bearing Buddy to use. The reason you have to go to such lengths to find out what Bearing Buddy Kit you need is that there are so many different variations in bearing/spindle/seal combinations that the only way to be sure you have the right part is to check the equipment you have. The skf Bearing Buddy pages also have listings on them for what bear.

Check the outer bearing and race numbers stamped into the metal of the bearing and race in the hub. Most 6,000 pound 8 lug wheels we carry use outer bearing # 14125A if it is an 8 on 6-1/2 bolt pattern. If it is an 8 on 8 bolt pattern, it may use # 506849 outer bearing. If you have the 14125A outer bearing, you can use Bearing Buddy Bearing Protectors.

In order to determine which iko bearing buddies you need, you are going to need to remove the hubs of your trailer and get the number off of the outer bearings. Most 6K axles have outer bearing numbers of LM-67048, 15123, LM-67010 or 15245 which all will work with the Bearing Buddy Bearing Protectors # BB2441 that you referenced.

Bearing Buddies like # BB2441 fit very tight into a trailer hub. In order to get them out, you will need to use a rubber mallet and persuade them out. Once the Bearing Buddy starts to unseat from the hub you can grab it and wiggle it out.The zerk fitting is a standard size. The fitting is threaded, and is secured by a nut located on the inside of the bearing buddy. You should be able to obtain a replacement zerk fitting from your local auto parts store.

Bearing buddies are installed on the hub of boat trailer axles. Original axle hubs only have a dust cap. They are a convenience because you can lubricate the hub bearings with a grease gun instead of taking the hub apart. They also keep the bearings from getting wet when the trailer is in the water during loading and unloading. "buddy bearings" allow more room for extra grease on the bearings. 

Grip the old bearing buddy with the channel lock pliers. Twist the pliers up and down to loosen the bearing buddy. Pull the bearing buddy from the hub using the pliers.

Remove the dust cap from the new bearing buddy. Compare the new bearing buddy to the old one to make sure it is the correct size. The open end of the new one should be the same size as the old one.Strike the bearing buddy as lightly as possible with the rubber mallet to install it on the hub.
