Bad coupler or bearing? Video inside

[Timing]

Im getting a weird whine down sound when my supercharger whines down and when i shut off my car.
Bad quality but you can hear the sound when i shut it off at end.

 

[brandonl2000]

sounds normal to me. just sounds like a 3800. perhaps some possible power steering noise there. but otherwise sounds normal.

uh

how are your fluid levels?

Have you tried the mechanics stethoscope?

you cant hear that sound of it whining down when i shut it off? My 2000 did not do this and this one did not wheni got it. Its liek it continues to spin after letting off. And ya im aware new ps pump this week

Edit: also when i really hammer on it it does the same thing when i let off.

i mean yeah but barely. mainly it sounds normal to me. i don't notice any problems per say.

I was thinking more along the line of power steering issues.

Its VERY noticeable off cam.
I did take a screwdriver to the nose and sometimes i can hear a click sound, thats why im guessing coupler.

Its something else, once you shut the engine off everything stops spinning. Maybe ac compressor clutch going bad that is the only thing I can think of that would continue to spin after the engine is off.

[brandonl2000]

Thanks brandon ya it stopped after taking off the second belt.
So either ac or ps? I know my ps pump is bad so ill replace that and see what happens

Just another side note if my ps pump is bad could i have unwanted tention/friction that could cause my gas mileage to suffer?

 

[Scottydoggs]

not likely, but if you drive with a dead p/s pump the rack will die, im talking past a whine, no power at all any more.

 

[brandonl2000]

so then it is bad to turn the wheels with the car off.. like if working on it.

 

[Scottydoggs]

doing it prolonged is real bad. if you were just pushing the car around, id try not to dry steer it, only turn the wheels when the car is rolling.
