I had my seals replaced at the dealer and it just feels stiff. Might just be me.
It's possible the dealer screwed up [too much] but unlikely. Give it some time and see how it feels out for you.
A couple of extra ounces [beyond spec] would make a difference [harder].
Were the seals leaking? If so, loosing just an ounce would make it softer. That could be the different feel you sense and became accustomed to.
