Question:
I am in need of a couple of rear seals for my Trailstar boat trailer. It is a 2005 PG16V trailer. The number on the rubber seal is AD2528E

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 like # 301-17068 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.
