hhmm, i did mine(on a X90 though) and didn't touch the front ball joints,
jack it up, take off wheel, unbolt front sway bar, unbolt lower bolts on strut,, lower A arm until spring slides out....reverse to reinstall
oh yeah, and in order to get the A-arms low enough to install the coil springs, i had to unbolt the axle shaft from the differential on driver’s-side, and slide the axle out on its splines on the passenger’s-side .
back is even easier,  raise car, take off wheel, unbolt lower shock, lower axle till spring falls out..
