My Sienna LE FWD with 55K miles makes has started making sqealing/screeching noise while making left turn. More so when making U turns. Never on right turns. Any clue on what could be going on? ---

That noise can occur when the brake pads wear to a point where the wear indicators on the pads come in contact with the rotors while making a turn. Have the brakes inspected. Tester ---

Brake pads are very new. Front and Back. I should have mentioned before. The noise occurs only I make left turns. Thanks. ---

Check the serpentine belt and belt tensioner. ---

does it make the sound if you are standing still and turn the steering wheel? is the tire worn more on the left front side than the right? ---

No it does not make sound if I am standing still and turn the steering wheel. All four tires have less than 2K miles on them. ---

Yes. I have Tire pressure has been OK. ---

Jack your car up, take off the wheels and check your outer cv joints. Double check your power steering make sure there is not a leak, and then if none of that is to no avail describe the “squealing” sound more, or upload a video to YouTube then link it here. ---

Have not been able to take off the wheels yet. But here is the [audio](https://www.4shared.com/s/fQgcyZ7Qhea) of this noise recorded while driving at ~5 mph in a parking lot. It sounds like metal grinding against metal. Starts at 3 sec in audio file. It appears to be originating from front right (passenger) side, close to the wheel. ---

That definitely sounds lie a dragging brake pad or wear indicator. ---

Thanks. Brake pads are quite new. Does this mean they were not installed correctly? Could it be wheel bearing? ---

Wheel bearings generally make a rumbling sound. Perhaps an anti-rattle clip was left out when the brake pads were installed or the contact points weren’t properly cleaned and lubricated. ---

Got it. Will this issues manifest only when the wheel is turned? ---

OK. Will need to go back to shop that installed the brakes pad. Not sure if its easy to find/buy just the clips. ---

I took off the wheel. Found Rack and Pinion Boot was damaged and leaking. Hardly visible from top. Will I need to replace the entire joint or just the boot? Image attached. Is it fair to the assume this causing the noise or I have two issues to deal with. ---

My thought, the boot does not leak unless there is a power steering fluid leak. ---

Rack and pinion boot/seal failure on the right side is common on 2007-2009 Toyota vehicles. The torn boot will not make a noise however the cost of repair will be much greater than the brake squeak. ![image](https://global.discourse-cdn.com/cartalk/original/3X/3/0/30504a6d700d2f583843de4a09fe3e740a7cc860.jpeg) [Steering rack leak - Toyota Highlander and Sienna, Lexus RX330 and RX350 (carspecmn.com)](http://carspecmn.com/steering-rack-leak-toyota-highlander-and-sienna-lexus-rx330-and-rx350/) [Next page](https://community.cartalk.com/t/sienna-2008-squealing-sound/181770.md?page=2)
