Truck has recently started making a noise... it can only be heard with engine under load (driving), not sitting in park revving the motor, a "whirling" and "whining" can be audibly heard from the engine bay/tire area, driver side.
The noise im hearing is engine noise im almost sure. But idk where. Without fail, everytime i slow down to a stop sign, or light, you can hear the "whirling" slow down with the truck...... Just out of randomness, today on the way home, i turned the engine off with it in neutral going 55mph so i could hear the drivetrain/tires/etc without a noisey exhuast.... as soon as it was off, and trans in neutral, i couldnt hear a sound... As i slowed down approaching my driveway... no audible sound was made from the truck... theres an engine related noise that is only audible when the engine is on and under load. Wtf?
Its not the rear end, at least i think. Its not excessively hot or anything.
And as i said, it only is heard apparently when the engine is on and im rolling at the same time.
What gives?
I know this like a total game of shot in the dark, im only really posting to see if someone has heard of such noises at these very specific conditions before.
I can try to get a video, but the truck is pretty loud... i can almost "feel it" in the steering wheel when slowing down (engine on)
Im thinking PS pump since its old asf, recently developed a leak, and i let it get a little low....
I filled it back up, same ****.
Thoughts?
TIA
