Hammering out and in worked for me. There are circlips on the EK4 though. just need a suitable pair of pliers for that though. (Gloves are advisable, not nice when they pop out and bite your hand!)
I JUST did one of these. I used the good ole splitter and hammer method. I recommend buying an OEM honda balljoint instead of some one off piece. If you have issues taking off the castle nut I suggest taking the splitter, pounding it on as hard as you can and have a buddy pull down on it as hard as he can. It'll provide enough friction to allow the nut to come off. I had to do this TWICE... -_-
no sir...I removed the hub assembly off of the car, put it in a vice, and my buddy who has mad strength beat the **** out of it till it came out.did you replace ball joint with arm still on car ?
