new owner of a GX 460.
noticed that when driving in the parking garage and turning around the corners, the wheels make screeching noise. the GX 460 is not a very big SUV but it feels like i'm driving a huge truck when trying to turn.

any ideas or thoughts? thanks.

and also need confirmation that during normal driving, the central differential should be disconnected, which means a yellow icon showing on the dial, i.e., a yellow icon that shows a cross in between the four wheels.

Thanks again,

it feels like a truck because its built on a truck platform, maybe take the turn slower? The wheel is light and the car feels like it can turn faster than it really can. Your differential should not be locked during normal driving, ie, no icon on the dash panel

might just be brand new squeaky clean tires

Thanks a lot !!!
very helpful that there should be "no icon" on the dash panel,
I thought the "X" over the four wheels means "UNLOCK", but seems that is not the case..
maybe that's the reason for the "heavy" feel of the SUV.
Thanks again,

You specifically mentioned a "parking garage" in your original post. The flooring material and your tires, together, will typically make a slight screeching noise largely due to the slick material of your "new" tires. Just like when you pull into your garage(if it even applies to you) and turn the steering wheel left to right. If it's still making that same noise on regular pavement, then it's definitely some thing else.

thanks for the advice.
turns out it is due to that locked differential (icon showing on the dash panel)

Not good to drive on dry pavement with it locked as it binds the drive train whilst turning. Hopefully you did not put a bunch of Tarmac miles on her with that light on.

drove it for 20 miles on pavement while the light is on, about 5 trips each 4 miles.
it was very difficult to turn at low speed in parking garage,
hopefully not much damage was done on her.
thanks...

She is robust. You will be fine.

Thanks a lot, seems things are fine, only the gas mileage I got during those 20 miles is about 6 mpg, now at 50 miles total mileage the mpg is about 10.
