Hi Bill,
Do The wobblies extend down under the bass strings? If you can reach the
bridge pins without spilling CA on them, that is the way you could go. Apply
thinnest with the piano at pitch, and on a 45% tilt.  Apply just above the
bridge pin so that it will run down onto the bridge. Then reapply a second
pass being careful not to let the glue run too far.
One other thing you might check is the bridge notching. If it is not
parallel to the pressure bar and you have unequal string lengths,
You will get the same sound as loose pins.
Love those wobbly knees.
