Recommended Grease Seal Replacement for Dexter 8-248 Hub

Question:

I was given a rusted old trailer that needs a lot of TLC. I want to start with bearings but damaged the seals. #58846 witch is a single lip was wondering if it will be okay to use double lip #10-19. Help. Hub has these numbers on the back if this will help. Dexter 8-248, 344, 2, AF.

I have a replacement for you; our # 58846 grease seal is actually a double lip seal like you wanted, and if that is the seal number you're finding on the back of your existing seal, you are able to use that as the replacement. For reference, this seal has a 1.719" inner diameter and 2.565" outer diameter. The 10-19 seal you mentioned isn't one that we carry, but if you actually meant the # 10-9, you wouldn't be able to use that seal since it is much smaller with a 1.5" inner diameter and 1.987" outer diameter and is designed for 2000-lb axles.

The Dexter 8-248 hubs you've currently got are likely 3500-lbs capacity similar to the Dexter # 84546UC3 which have a 5 on 4-1/2" bolt pattern and use inner bearing # L68149 (1.378" inner diameter of bearing) and outer bearing # L44649 (1.063" inner diameter of bearing).

I've also attached one of our help articles on bearings and seals that breaks down all of the different sized bearings and seals that you'll find on different axles, as well as their measurements; you can used this to cross-reference in the event that you find a bearing/seal/race that doesn't have a legible number on the back.
