increasing whining sound

[tonic]

I am having exactly the same Issue. I don’t know what to do.
I don’t want to use the sprays since my belts are relatively new (2 years).
My car is Camry 1996 4 cyl –
Toyota dealer did my timing belt - and they put new driving belts like 2 years ago, new water pump etc (that car was 88k miles)
Now I have 120K miles and like 1 week ago it started –
its doing that weird squealing noise/ it’s coming from the front of the car
First time when it did - was just a short squiiiiizzz (4 seconds) when I was taking a wide curve to the left - I was surprised, hmmm
So it did like this for lets say 1-2 days - a few curves to the left (just to the left) and that short weird sound (harsshhhhhh….for 3-4 seconds in wide curve)
To mention nothing yest in any short slow curves – just wide with at least 25miles/hour
Initially I was scared its something wrong with the Power Steering Pump?!
So I have checked the level for the power steering fluid, but was fine – nobody touched the power steering fluid ever but was just a little-little bit bellow the mark.
So next day I was to the dealer to change the oil and I put a note to add some Power Steering fluid - they did that, they put a little bit over the limit-mark.
Anyhow I left the dealer – and I realized that was not resolving the issue.
First curve – and it seems it started longer now …
I have left my work – and it started to do more often – to any left curve, except the slow curve (90 degrees).
Next days I have checked the level-nothing changed - is not loosing any power steering fluid.
But now the situation is worst. I mean lets say I take a left - it will start doing that weird noise/squealing and is not stopping for the next 2-3 minutes - driving straight the sound is not stopping.
This morning I left - and it started after I left the parking – and to mention again is not squealing at stop - in parking –
Also as soon as I hit the breaks-or the car is slowing down - the squealing -weird sound is fading away.
I can't detect exactly where it came from / I mean which belt?! I am thinking is the power steering belt - but how I said all of them are new. I have checked with my hands - but it seems are tighten enough?!
Any clue?

No answers, just questions. You mentioned that the squeal gets quieter/lower pitched as the car slows down. What if you speed up? Does it get louder or higher pitched? Is the changing pitch of the squeal more related to the engine RPM or the speed of the car? (try doing it with the car in first gear compared to 2nd or 3rd gear).

I tend to suspect something in the system that only happens when you turn left so that should exonerate the power steering pump or belts (they should work the same turning right or left). However, it may be a restriction in the power steering tubes or something with the wheel and or suspension. Could you safely lift the car on jack stands and duplicate the noise?

You mention when you apply the brakes that the noise does not go away all at once but that it fades away. I presume that you mean that the squeal is relative to the speed of the car. If this is correct I don't believe that your brakes would be the culprit.

You point that it continues even after you have straightened out has me confused.

Sounds like the belt is loose. After a new belt is installed it needs to be re-tightened after a few weeks or whatever; unless you have an automatic tensioner which your Camry does not. Its not the Toyota dealers fault.

you need to re-tighten the belts, no questions about it.

could be your power steering belt, or your alternator belt. but regardless, they just gotta be tightened. it's a ten minute job, tops.
