I'm unable to look up which Bearing Buddies you'd need for your 5th wheel, but it's pretty easy to figure out which ones you'll need.

All you'll need to do is figure out which outer bearing the hubs use. Pull one of the hubs and carefully pull the outer bearing and wipe it down with a paper towel. The bearing cage should list a reference number on the side, such as # L44649. If you look up the # L44649 bearing on our website, you can see that it uses the # L44610 race which has a 1.980 inch outer diameter which would be the same outer diameter that the Bearing Buddy you use would need to have. In this instance, the # BB1980A-SS you'd looked at would be the correct Bearing Buddy fit for a hub that uses an # L44649 or # L44643 outer bearing.

If the bearing doesn't have a reference number on it, use a digital caliper like part # PTW80157 to measure the bearing's inside diameter (a ruler or measuring tape won't provide an accurate enough measurement).

I've linked to a table that matches up the bearing reference numbers to their inside diameter and to which race they use. If you struggle with the linked chart, you can simply reply with the inside diameter of the outer wheel bearing and I'd be happy to figure it out for you.
