My local GM dealer tells me he has New Bearings and Races for replacement but the Seals are no longer available PN 3998 519 later to PN 554 931.
Question, were can I find New Axle seals for a 10 bolt posi?

Thanks Tony

Just about any auto parts store will have them. The 8.2 10 bolt, 12 bolt, 8.5 10 bolt and 7.5 10 bolt car rear ends all use the same axle bearings and seals.

Take your old seal to a local bearing supply house and they can match it up for you.

Thank You guys.

Tony
