I'd flush that PS fluid out man. I know somebody who put PS fluid in his Tacoma by accident and it started to leak 10x worse. And stopleak is great for clogging things up. It's kinda like having an air filter with a hole in it and stuffing the hole with seran wrap to close it up. Not the right way to do it.
Verify that it's your pump making the noise and then swap it out, and viola
...and use ATF
