So my brother has an 04 WJ 4.7 and has recently gotten the power steering pump replaced with a new one by a trusted family mechanic and it was working perfectly for about a week. At that point it would immediately make a terribly loud whine at idle after start up, and now won't stop doing it. We checked the fluid multiple times and each time it is a milky chocolate color, which I have come to learn it means water in the oil. So we called the mechanic (who is 2 hours away in our hometown..were in college) and he said to flush it 2 or 3 times with some fresh power steering fluid. My brother went to advance and came back with ATF-4 saying the employee recommended it over normal fluid since it was a jeep for some reason, I wasn't there.
But anyways, we have flushed it twice with the ATF-4 and the problem still persists. I was wanting to see if anyone has had a similar experience so maybe we could fix this ourselves before we have to figure out a way to get his jeep back home over thanksgiving break. I would like to avoid driving anywhere it sounds way too bad.
