If you're leaking by drivers side, then it's the rack. These do go out often. There is a circle, joint, looking thingy on the rack closer to drivers side where fluid leaks from. If you were to jack the car up at a shop, and turn the wheels with it running, while standing underneath, you would be able to see globs dripping out. It is possible to disconnect lines from the top of the engine. I did it that way with an offset wrench I bought from Autozone, 16 and 18mm I believe. Quarter turn at a time, but I found it better than wrenching from underneath. Put a board over the engine and an old blanket on that, lay on that and turn. If you pull the rack out, try to do it out the passenger wheel well. You don't want to disturb the likely, very rusty, brake and fuel lines on drivers side. Having those start leaking will turn into a big costly problem. I did this not too long ago, there are pictures in my ride thread somewhere. My fuel/brake lines where out though because I was replacing them. Jack car and remove wheels, unhook lines, loosen the tie rod connections, loosen the rack mounting bolts, remove steering shaft bolt, drop subframe, and you're on your way. I used an ACDELCO Pro Reman rack from RockAuto. Good luck.
