Connecting the netural and ground at the disconnect (or basically
anywhere other than the panel) gains you nothing at all, is risky, and
could be made even worse unintentially by someone who doesn't realize
the circuit was done wrong.
Tying the neutral to the ground gives you no advantage at all in the
case that there are no failures (broken wires, broken connections,
etc.). And in the case of failures, it can make things worse than they
otherwise would be.

All.

I will make sure the disconnect, when replaced, has the neutral running
straight through - using a wirenut - and does not connect to the
ground. I will connect the ground to the ground bar in the disconnect.

Thank you.
