Mine were not leaking at 106k miles when I replaced them couple months ago but my left strut mount had big crack in rubber.
Obviously, my wheel / tire combo is much heavier and less rubber meat than yours so that's a big factor in wear.
Regardless, I can guarantee you that at the age and mileage you have, yours are definitely tired and you'd benefit from new set.
