Alright, I'm done. What did I learn? Seat that gear onto the pump properly. I had to take it to my buddy's shop and he used his press to get it on just another mm or so. That quieted things down.
Next, the return line has an o-ring where it connects to the PS pump. Mine was brittle and separating that line from the original pump compromised its sealing properties. It was leaking like a sieve on the new pump. I had to get an o-ring for it and it's sealing properly now.
After all this, I had to bleed it......for the third time. I'm mainly posting this part here to remind me of how to do it and i'll apply it to my other cars. Who knows, maybe it'll help someone.
Since I had to refill the fluid after replacing the o-ring on the return line, I didn't have the opportunity to prime the pump. Nevertheless, my method worked first time.
First, After filling with fluid, raise the front end tires off the ground. With the engine not running and the reservoir cap removed, turn the wheel lock to lock. Touch each side about ten times. Next, start the engine and repeat however, this time, when you lock all the way to each side, hold it there for about 5 seconds every time. Again, about ten times per side. Now, lower the front all the way down. Repeat the previous step with the tires on the ground this time. That's it. Put the cap back on. Take it for a drive, check for leaks, and have a cigar.

. If after that, you still hear whining when you turn, you may have a leak that's bringing air into the equation. Ask me how I know.
