I have an 83FJ60 that upon start up I get a whine from under the engine bay at 2,500 RPM. This only happens the first couple of shifts then goes away. The truck is desmogged so I know it is not the air pump since I have had this happen in the past when the smog/air pumps go bad. I fear this could be my power steering pump going bad but am not sure. It seems like the power steering pump is weaker than it used to be but the change could have been progressive so I am not sure. I am not running the A/C when this sound occurs and I do have a Jim C smog pump idler that is only 1 year old.
Will a power steering pump on the way out whine?
