yeah i know that the only solution is to replace the seal, that part was a given. and when a dealer replaces the seal arent' they required to check the bearing for fitment anyways? i would certainly hope so.
i'm more concerned with the vibration as the seal is an easier job. it wouldn't be crazy to think that the vibration and seal were/are caused by a failing u joint would it? gas applied doesnt seem to affect the vib at 40 or around 65 and i can slip into neutral at those speeds and it's still apparent.
