Does anyone else have a slight squeal while steering the vehicle to the limit of it's turning radius? I've just begun to notice this recently on my 07 GX... mainly when I'm pulling into a parking spot at slow speeds. Is this normal or should I have it checked out at Lexus dealer?

 

Easy things first...Have you checked your power steering fluid level?

 

squeal? are you sure it's steering mechanics and not the sidewalls of tires? Steering mechanisms usually grind...

 

I believe every car with power steering option has a slight squealing sound comming from the pump when you turn your steering wheel to it's lock (end of travel) limit position.
