Part AD2528E is a double-lip grease seal from NOK that cross-references to National seal part 470460. My research shows this seal has an inner diameter of 1.688-inches and an outer diameter of 2.560-inches. The nearest item we have is part # 168255TB which has an I.D. of 1.687-inches and an O.D. of 2.561-inches.

If you have a digital caliper you can measure the spindle diameter where the seal rides and the hub bore where the seal installs to confirm the inner and outer seal dimensions you need for a replacement. Please refer to the linked photo.
