    It feels like the side swing is starting to get weak, what could cause it other than the turntable motor?

    Likely the swing motor. There's a case drain test in the manual to determine for sure. If you feel lucky you could swap the relief valve for that function with one of the others, might have a weak of partially stuck relief valve.
