My A4 is leaking badly out of the rear seal. I pulled the coupling and seal carrier, and the coupling is badly grooved where the seal rides. I see this part: Repair sleeve for output coupling, OREV_06_170, which is SS though only $4 less than a new coupling.
I am assuming that this is to repair just such a groove, and that once installed, should be more durable than the original mild steel sealing surface. Is this all true, and if so, does it come with instructions?
