My 12 bolt pinion seal was also leaking. Replaced the seal twice, still leaked. I found out that it was leaking around the OUTSIDE of the seal where it meets the housing. Housing was pitted pretty bad, so I ended up putting some RTV sealer around the outside of the seal before installing yet another new seal. That finally fixed the leak. You may want to look at that area on yours to eliminate that as the leaking area.
