Unfortunately No. I use cast Iron in all my installations even where plastic is permitted.
The problem with some installations is the piping is not always secured properly and this makes for either a noisy or loose system.
There is always the possibility the toilet flange was not secured to the soil pipe properly or the floor flange maybe too high for a proper fit.
Sometimes the builder hires the plumber who comes in at the lowest price with total disregard to quality in materials like an imported flange which is not supposed to rust but some do.
The flange bolts have this flat bottom that is supposed to fit in the floor flange BUT if the flange separates from the soil pipe Or the groove opening is too wide then the bolts just become unattached and thus causes this kind of condition.
You may want to lift the toilet up and install Hercules Johnny Bolts BRASS and a Hercules wax Gasket with the horn for better sealing.
Most decent home centers carry this. Good luck
