Air chisel did the job on the UCA bushings I crushed the sleeves into themselves a little to relieve the press fit then hit and pried on the flange and after a while they came free. Unscrewing the upper ball joint was much worse I ended up dragging the ox/a torch out and using a six foot breaker bar before it started moving and that was still giving it everything I got. And I’m 6’3” 300lbs!
