Oil Seal for UFP Trailer Buddy Hubs

[shade]

One of the inner seals on my Trailer Buddy Gold series (oil bath) hubs is leaking pretty bad and needs replaced. I have the part# for the seal, but I'm having a hard time finding it online and locally. Has anyone purchased them online?

The industry standard number is 256-168-SP2-1

The NOK part# is AE2528EO

Also, if anyone has ever changed one of these seals, was it difficult? Should I attempt it myself or should I take it to someone and have them replace it?

TIA

I have a National (Federal Mogul) number you can use or cross reference. 470460 The size is 1.687 x 2.561 x .500. Changing one out is no different than doing a grease seal.

Thanks guys.

I emailed UFP and they gave me their suppliers info. (Waymire Distribution). I called them up and ordered the seals.
