ugh damn. Hit your friend once for me, you are not in for an easy task. 99% of the parts stores you go to will tell you it cannot be ordered seperately. That is incorrect. I ended up buying mine at NAPA for $70.
I am not sure if you can just re-boot it or not. If you could, it would make life easier.
To remove mine, I had to let it soak in penetrating oil for a day or so, then heated up the knucke around it, and simply slammed that thing upwards with a sledgehammer. (it is not easy).
I tried everything under the sun to get the new one in, froze the ball joint, heated the knuckle, sledge, ball joint press, lube, everything. After a few days of absolute agony, I opted just to pull the whole knuckle off and take it in to my local honda shop. They actually pressed the new ball joint in in about 5 minutes and charged me nothing.
In summary, if you cannot re-boot the joint (i dont think you can) then I suggest you pull the steering knuckle off and take it along with your new ball joint into a honda service center and let them install the ball joint.
hope I helped.
Good Luck.
