Well the seal is still leaking, looks like I may just have to go to the dealer.
It only leaks after I've driven it around, won't leak just sitting in the garage overnight. I'm frustrated to say the least. I've now installed it with a new seal (verified it was Passenger side part# 806735230) and a reman axle from autozone part 7336. It leaked so I exchanged it for another 7336 at autozone in case something was bad with the first axle, and I bought another axle seal from subaru. I went to a hardware store and bought a short pvc adapter that just fit over the outer edge of the seal and used that to install it into the transmission so the seal edge, the hard outer part, is flush with the transmission face. I used some transmission oil to lube the axle as I carefully installed it into the transmission, so I really do not think the seal was damaged at all. All I can really think is that these autozone 7336 axles that were recommended in this thread are not so great anymore. Maybe however they remanufacture them now takes too much material off where the seal meets the axle?
Anyone have a stock subaru axle laying around and could measure the diameter on the axle where the seal sits? I returned my stock axle to autozone a while back for the core refund.
