Steps

Clear out the cabinet and lie down with a light to see the sink underside.
Replace broken mounting clips one at a time, keeping even tension across the rim.
Renew the strainer flange seal with plumber's putty on the top side.
Tighten in a star pattern and test the rim for rock before reloading the cabinet.

Maintenance

Push down on the rim yearly to catch clip creep early. (Suggested interval: every 1 year.)
