Need help troubleshooting this sound - Video

[Freebeer187]

This sound has been getting worse over the weeks. At first it would do it when the engine is cold, but now it does it at all times. The sound is louder when the wheels are being turned even when the car is not moving as noted in the video. The sound goes with the RPMs of the engine, and get louder/higher pitch as the RPMs rise.

In the video when the camera is resting on the windshield, the diffrences of sound is being created because I am moving the steering wheel. Any idea what this is? It sounded loudest around the alternator. I recently got the belts replaced about ~500 miles ago. I can't recall if I heard it before or after the repair.

*Possible volume warning*

Damn just watched a YouTube video looks like a bitch. Is my assumption correct?

 

[RICH17]

Its not really. Pull the overflow. Alternator. tensionor assembly with the coolant elbows. Take of front wheel to pull the lines. And unbolt it. Gotta rent a pulley puller tho cause new pumps dont come with them.

 

[Freebeer187]

Yeah I'm going to have my go to mechanic tackle this one. Gotta get a wheel bearing replaced too

Thanks for the fast reply!

 

[RICH17]

Labor cost will kill you. I can do it and give you a way better price on doing both parts I'm sure

 

[Freebeer187]

Tell me about it. These shops around town are crazy. Would you fix it at your place? Aren't you like down the street from me?

 

[RICH17]

Yup. Could do it next weekend.

PM me if you want

Many times it is just low on fluid (didn't watch video, cant have sound right now) I'd try that before replacement. Mine gets loud every few months, throw in some fresh Dex 6, sound is gone again.

What 02BlueGT said . Power steering fluid is lower in the tank when its cold out . If you have lost more fluid then it will squeal all the time .

Anything leaking or wet underneath the car ?

Good point. It has always had a ~dime size drop every now and then of oil, which is coming from what I believe to be the lower oil pan gasket. Not worried about that.

I don't believe its leaking, but I will take a closer look at it tomorrow. I just found this page, and it is my exact car down to the year! Ill use this guide to troubleshoot the issue.

Im going to at least check out the fluid. Well see how it goes. Didn't hear the sound once on the 30 minute drive home today.

Make sure you have on thick sleeves, or do it when the engine is cold since you have to reach around the alternator.

 

[Freebeer187]

Thanks I will keep that in mind

 

[RICH17]

I figured you had already checked fluids. Whoops

Thanks for this. Added some of this today and it runs perfect. It might be in my head but the steering feels smoother. When I took out the dipstick/cap it was empty. As I added the Lucas stuff, I noticed when I would add the dipstick to check my level, it would be covered with a thin brown liquid, probably the little that was left in the system. I used about half the bottle (small bottle).

 

[RICH17]

Good. Now hopefully that doesnt run out from a leak. If there is one
