Squealing Left Turn (without brakes) - Video Inside

Hi RFD:

Hoping someone can shed some light on this. I have a 2007 Lexus GS 350 AWD that squeals when I do left turns. It doesn't necessarily need to have brakes applying while turning for it to squeal. It's gotten progressively louder over the past few weeks. It's also sometimes doing it with right turns now but no where near as frequently or loudly as left turns.

I know the car is known to have squeaky brakes but this noise is without the brakes being applied so I don't believe it's that...

Anyone experience anything similar or have an idea?

I suggest you only make right turns.

I second ball joint as the cause.
It could be as simple as a ripped boot and all the grease has dried up or the ball joint on its way to separation.

Jack the left side up and rock the wheel (holding the top and bottom) and see if there is any play.

Tried it... kept wondering why I was passing the same building over and over.

I initially thought this too but my mechanic took the brakes out last time I got an oil change and he cleaned them out but it didn't do anything. Also, could it still be the brakes if the brakes aren't being touched at all when I do the turns?

Hmmm if it ends up having to be replaced, is that a relatively expensive job? I imagine it's recommended to do both sides at once?

I just did a quick check and it appears you will need to replace the control arm with the ball joint already pressed in, which would be 2hrs or so labour at a shop.
It's not hard as a DIY, removing and installing the control arms.

It definitely sounds like brakes to me. It sounds like the metallic pads have gotten hard from heat and will continue to squeal until you either replace them or sand them down until
you get past the hard part but my advice is replace them with rotors. Now that is only from a 25 second sound clip have your mechanic do another diagnosis.

Ya brakes not ball joint. Sounds worn to me with the wear sensor touching.

Sorry, I should've mentioned that the front brakes were changed back in December I believe. My mechanic also checked out the brakes when the squealing started a month or so ago and the brakes were fine.

So took off the wheel earlier today and the brake dust shield was pretty warped. Funny thing is that I didn't see where it would be touching the rotor (if the noise is the brake dust shield). Will probably bring to mechanic to hopefully take a more thorough look..
