On my grand prix gxp I replaced the cv half shaft and the seal on both sides of my car. On the passenger side the seal was leaking prior to replacing it. I figured replacing it would fix that. Well it didn't. I am on my third seal and each one has been a different brand. I bought the one today from dealership because they swear that it will fix the leak. But I have measured the inner diameter of it and its the exact same as the other ones. Anyone have any ideas as to why it would be leaking tranny fluid at that seal?
