Engine/Transmission (1998.5 - 2002) Help needed - power steering leak

[Just_George]

So, every night when I park my truck (inside) it pukes power steering fluid all over the floor. Not just a little, but a bunch. Seems to be more affected when it's cold outside. I can't yet spot the source of the leak - sprayed everything down with engine cleaner and will try to watch a bit when I park it tonight. Saw some comments about the vacuum pump seals & rebuild kit as a possible cause/solution, but this one is just a bit outside of my wheelhouse. Comments or suggestions are appreciated!!
