changing power steering fluid

hey there you guys . i wanted to know what is the best way to change your steering power fluid. maybe to disconnect a line but where? or take a syringe and squeeze out some and drive a bit, and do it again? any opinions, tanks.

The only way I've heard of doing it is using a turkey baster to suck out all of the fluid in the sump and then refilling it with new fluid. This process is repeated for several days after the car is driven until the fluid appears to look "healthy" (for lack of a better term). Has to be done repeatedly because a lot of the fluid isn't in the sump. If someone has a better way, well, I'd love to hear about it!
