I un-clipped the wheel well clips that attached to the subframe bushing bottom retaining plate.
Next, I used a 25″ 1/2″ breaker bar with a 21mm socket to loosen, but not remove, all four subframe bushing attachment bolts.
The next step, is to replace the bushing retaining bolts with a extension rod and nut combo that is longer then the attachment bolt. 4 rods will be placed in place of the original attachment bolts. The longer length rod will permit the suspension subframe to be lowered 2.5″ to permit the bushing tool to have enough room to operate.
