all you need is a ball joint seperator(pickle fork), the BIG socket and a LONG breaker bar. they are threaded into the upper A-arm. mine took a 6 foot pipe to get enough torque to break them loose. they are much easier to replace on the car then in a vise. there is a special socket( that was covered with dust) that I borrowed from an alighnment guy I used to work with. with out the socket some claim it is possible to get them out but dont hold your breath. find the socket and do it right.
If you want to hear me ramble I'll tell the whole story about replacing mine.
