DG gone crazy

Just got my PA-28-181 back from the shop after replacing the left mag, and now the DG is going crazy. It spins like crazy, until I push the adjustment nob, and then it will hold for a few minutes before starting again. Anyone have any tips or tricks? I am trying to avoid having to overhaul or replace until after trying any ideas you all might have.

Thanks in advance!
