whining noise (video)

I had already posted about a whining noise, thought it was my power steering pump, but it wasn't, I've replaced pump, and both idler pulley's. still no change. the sound originally started at random, and actually right after I installed a leveling kit. I took some video, and regardless of being in drive, or park, or neutral, or speed it still makes the whine, it gets louder with RPM's only. steering back and forth does not effect the the whining noise. HELP, Dealer wanted 230$ to diangose, which I think is crappy, so I'm taking another jab at this, hints why I'm including video's this time.

one video is in park, the other is while driving, and hitting a few speed bumps.

Well as stated, I replaces the pump, as well as the idler pulley's. Before I changed the pump I had flushed the system as well and replaced fluid and no change. Temp of fluid doesn't seem to matter, maybe a slight bit louder, but only I can tell cause I hear it everyday.

Your Video clips didn't help... since you installed a leveling kit it could be the flex pipe(s) from the exhaust manifold that leads to the turbo, look for leaking. it is pretty common that pipes get stress out when changing truck height

Somebody on another forum mentioned that it sounded like diodes on the alternator

getting that same noise that you describe. sounds exactly like a power steering pump low on fluid. my fluid level is fine, and the noise doesn't change when i turn the wheel. only changes tone when i accelerate. seems to get louder the colder it is outside. this morning was 4*F and it was the loudest i've heard it to date. seems to get more quite when the truck is all the way warmed up.

so i double checked my power steering fluid level.. it was just a tad below the min line. stopped at walmart and picked up some Mercon V ATF and filled it to the max line. The sound is gone. Hope yours is as easy to solve as mine was... not sure why mine was low. its not leaking anywhere.

My fluid is on the full mark and has been that way. Luckily yours was a simple fix. Mine on the other hand is not being so simple
