I did not do a flush, but I did bleed it. Hopefully it's just the pump because napa will replace it for free, I'm just surprised it was fine for a couple hundred miles. Ill flush it when I replace it this time
I have a 2003 4runner v8. About a week ago I replaced my power steering pump with one from napa because mine was whining. Was fairly easy to replace and went smooth. Worked great for about 150 miles. Tonight I took an hour long drive and a loud grinding began. The grinding randomly goes away now...
