I would be careful using that ford 51098 seal,as it is a thicker body and the A7 bearing retainer "will/could touch" that seal and concave the seal ...and could cause that type of seal to leak..IMHO
but if you've used it and not had a problem all the power to ya...plus its a bunch Cheaper than the 481837 Nat seal.:)
