My research on your boat trailer tells me that you likely need the following:

-Replacement OUTER Trailer Hub Bearing - # L44649 (I.D. of 1.063")
-Replacement INNER Trailer Hub Bearing - # L68149 (I.D. of 1.378")
-Timken Grease Seal - Single Lip - I.D. 1.750" / O.D. 2.565" # TMK29ZR

In order to make sure, you will want to wipe the grease off of your current bearings and check for numbers, making sure they match the numbers above. You can also take a digital caliper such as # PTW80157 and compare the inside diameter of the bearings and seal.

Titan acquired Dico some time ago, so the Titan 45264 hub you have will actually be the exact same as the Dico 45264. So with that being said, the CE Smith #CE13511 will be a good replacement. However, the Titan/Dico hubs did utilize a different size…

If the spindle is damaged, it'll need to be replaced. The #CE13511 CE Smith hub is compatible with a 3500 lb axle that uses an L68149 inner/L44649 outer wheel bearing and a 10-19 grease seal. For a spindle, you'll need a 3500 lb spindle, but…
