This probably does work quite well for your short spring coilovers, but if the OP's car has 2-bolt lower control arms and stock length springs, your method has no chance.
On 2-bolt LCA cars with stock springs, with the suspension at full droop, the control arms are metal-to-metal in their pockets in the subframe, there is no give to lever them down any further to pull the knuckle pinch off of the strut body. The knuckle has to drop an additional 2" from full droop for the pinch to release from the strut tube, and there is just no more downward movement when the LCA's hit the subframe.
You can try this, in post 14 I detail the Ford shop manual procedure for a '99 2-bolt, but it really doesn't work, because you're left with the all the mass of the knuckle hanging on the end of the half shaft, you're trying to work a knuckle pinch loose that's frozen and rusted to the strut body, and this is a disaster recipe for pulling the inboard CV joint apart and ripping the boot, BTDT.

I suggest doing the extra steps (10 through 12) I added. I recently did this again, pulled off BAT struts and stock springs to install my front coilovers, and I even pulled off the LCA's just to make the job cleaner.
OP, if you have 2-bolt LCA's, they're probably shot, if you haven't finished this job, just go to Vatozone or Advance and get some new front LCA's, you're going to need them. These cars need LCA's more often than they need clutches.
