not the RTABs.
there are dozens of bushings in our cars.
the Subframe bushings were not installed correctly.

1) the bushings are directional, so they have to be facing front and rear instead of side to side; which greese monkey didn't care to line up.
2) the bushings have to be pressed in from the bottom, so the subframe is pushing down on the sleeve of the bushings when torque shifting take place - mechanic got at least this partially correct, see next point.
3) the bushings have to be pressed in EVENLY and all the way on all four sides - mechanic pressed in all but ONE (front right side) all the way. that one bushing was about 5mm-6mm not pressed in, so the whole subframe was crooked and over couple of thousand of miles caused too much stress on the front righ subframe mount, in effect causing a crack. (have taken subframe out myself three times, so i know for sure the crack wasn't there before, should've done pressing the bushings in myself, like i did in the DIY here without the tool).
