PS leaks

Looking for leaks today while changing the oil I degreased the engine with "Purple Stuff" and a pressure sprayer. Oil filter housing is leaking, but what I thought was oil cooler line leak looks to be from the power steering pump. Not a bad leak, but a leak. Needed to add about 4 oz of PS fluid and after a highway run the PS belt is wet and drops of fluid on the front of the engine.
I have searched the old posts and found some info but not all. How hard is it to rebuild these pumps? Do I need a press to R&R the front seal on this pump or can it be done without one? This is on the 83 300d.
