One fix, "back in the day" was to glue a piece of blue teflon material
onto the backside of the spring. I'm not an ME but I'm guessing this
changed the natural freq at which it would oscillate.
I don't know what the material was (other than "teflon"), but I seem to
recall at least one mfg did this. some of those memories are a bit dim :-)
