Hum...or...whine...or what? And why?

[ridindirrty]

What up peeps, sorry about all the q's but I'm still learning (and liking) this car. I've noticed a new and unnerving hum coming from the engine/tranny area (haven't isolated it yet). Sort of a mid pitch whiny hummmm consistent with engine speed. It's there in all gears incl. P & N. Thought it might be the tensioner pulley (bearing on the outs), changed it, still humming. This is not the brake pump, not radio noise, so what? Power steering pump? Is this an AOD symptom? Anyone have a similar issue? Thanks.

I'll bet five bucks on the power steering pump.

Get under the hood and track it down. Use a long screwdriver as a stethoscope if needed.

Power steering pump

My '85 GT makes that signature Ford PS pump whine as did my '82. This is something different. It's also a new development (wasn't always there) but who knows, I've never had one go bad on me. Maybe this is how it starts.

You can flush it and try some lucas additive first
