After checking the suspension you should try a Wall shelf made for the TT. Like this
Pro-Ject Wallmount it 1 Turntable Shelf-Audio Advisor
This helps to eliminate foot falls since it is mounted to the wall instead of sitting on the floor. Another way with suspended tables is to hang it from the ceiling. This takes some knowhow to do but is very doable if you know how to find the ceiling joists. I used this back in the 70’s & 80’s with great success..
