Unhappy Power steering pump whine, fluid boiling...

I've been having to refill my PS fluid on a weekly basis due to a leak, so today I flushed out my PS fluid, took off the resevoir, rebolted it, and refilled the resevoir, and now the pump starts to quietly whir with the engine rpm level after ~5 miles of driving, and progressively gets louder and more excruciating...it also groans when I turn. I don't notice this whir/groan when the engine is cold.

I checked the PS fluid each time after stopping, and its boiling/bubbling, so either its too hot, or maybe the bubbles are just trapped air getting out. I did overfill the resevoir, so I removed some of the fluid, but the problem was still there after another 10 mile drive.

Based on a search, I think I'm going to lock the wheel from right to left a few times after starting the car for the next few days, and see if the air works its way out, and the noise dies down. I'm also going to be watching to see if the fluid continues to leak.

Any insight is appreciated.

Dont bother posting this stuff just email me direct!
Been there done that, rear bearing is stuffed because of belt being too tight at some stage, take it apart, remove the rear bearing and press in a caged needle roller bearing after opening the old hole to .512" (9mm) approx, replace the front bearing at the same time, its worth about $20 all up from a bearing supplies shop and any machine shop can open the hole out for you successfully.
Try synthetic gear oil in it I found that helps if you can't do the above mod.
They all suffer from this in time, you can't get the rear bearing from Subaru, only a complete rear housing so forget that idea.
Taking it apart and putting it back together is a piece of cake for even dumb people.

Not to be an ass.... but maybe us "dumb" people can learn from it being posted here... unless you all of the sudden want 23k emails from the n00bs filling your inbox?

"DING... you have mail!"
