I've done this...
After loosening and lubing everything, I banged on the knuckle like **** to slide it down the strut with a big, heavy, hammer that was my grandfather's. I also used my largest flathead to spread the knuckle apart. Honestly, once I had the pinch bolt loose the knuckle was open enough to slide a little bit without having to bang. By the way, leave the strut bolted into the tower by the top three nuts. Break them loose but do not remove them until the knuckle is off. Anyway, slide the knuckle down as far as you can with a hammer. Now it's pry time. Use the longest, strongest thing you have (I was able to get by with a 3 ft crowbar) and pry the knuckle down. I stuck the end of the crowbar against the underside of the frame and across the knuckle where the brake caliper bolts on (I removed my calipers btw, I needed to service the slider pins anyway). I then stood on the crowbar which slid the knuckle down a little further. I was about an inch away from freedom with seemingly no more room. What now? I slid my jack under and used a small ( I would estimate about 14-16 inches long), but sturdy, 2x4 placed between the bottom of the jack and the underside of the endlink mount on the strut and jacked the strut up about an inch or two. This can be dangerous so be careful. Position the jack so the strut will not move in any direction other than straight up or it can snap out. Once raised a little bit, I was able to gently pry (using my previously mentioned crowbar method) the knuckle off the strut without causing the strut to move, which result in it snapping out. I then lower the jack and thus the strut and pull the jack out. Things to note at this point, freedom! However, if you still have the LCA's and strut rod attached the knuckle and the strut will be "bothering" each other. Simply push the knuckle down out of the way, if you have a helper, while you go up and remove the three bolts holding the strut in. I did this alone so I rested something moderately heavy across the LCA's to hold the knuckle down while I removed the strut.
And that's how I've done it. My strut jacking method can be sketchy. It will take some attempts to position the jack so the strut doesn't snap out when you raise it. To anyone attempting this, be careful please! And I am not responsible for damage to you, anyone else, or your car.
