    Hello everybody, I have been browsing this site for some time and I figured today was the day I gave my first "help me" post lol. I have a 2006 tacoma with the 4.0 w/ 120k miles. I am getting an extremely annoying "screeching" sound upon acceleration. I replaced both upper and lower idler pulleys today, as well as the tensioner and a new belt. I was sure that this was going to solve the issue, guess not. My only other guess would be that it is the power steering pump making this irritating noise? I noticed the pulley attached to the pump has a minimal amount of back and forth play in it.
    Any help/suggestions is appreciated. Thanks in advance.

    Wild-ass guess here, but could it be the fan coming into contact with the shroud when the motor twists a bit on acceleration?
