Yup. Pishta posted about that sometime back. I should take a magnefier to see if the dimple at the bottom of the cup is really a pin hole.
Now I know the rear (input) is not the main issue, I'll leave any disassembly to the repair shop.
I still need to figure out if the drive cable and cable housing should be replaced. It's hard to imagine there isn't some wear considering the miles.
