Availability of Grease Seal for 2,500 Pound Boat Trailer Axle with 2.33 Inch Outer Diameter

Question:

I have a 1998 boat trailer. Tandem 2500lb axles. The hub is a UFP HD-1377-10 outer bearing is L44649, inner bearing is L68149 inner seal is NOT the typical GS6 Ø2.56inch OD and Ø1.72inch ID. The OD of the seal is the same 2.33inch as the OD of the outer race of the L68149 I cannot find this seal. I think it might be the 168223 or the 10-42, but Im not sure. Any idea? Only letting me upload one image, sorry. Thanks,

The closest grease seal we have to the dimensions you listed is indeed the # 10-42. This particular seal has the needed 2.33 inch outer diameter but a slightly different inside diameter of 1.75 inches than what is typically found when paired with the # L44649 and # L68149 bearings.

This may very well be the correct seal for your spindles but I recommend measuring the spindle where the grease seal rides with a digital caliper to make sure its matches the seal's inner diameter. You can also take a look at the inside of your existing seal to see if there are any part numbers stamped onto it. Just let me know if you find a number and I will be happy to see if I can cross-reference it to a matching replacement.
