I’m getting a strange squeak or a bird whistle noise when I’m driving and making a turn. Stationary and turning wheels I get no noise. And it’s particularly when making a left turn. Does it right as well. 

I did wheel bearings, rotors, and pads about 3 weeks ago and everything has been fine since. This literally started yesterday after I parked and then drove back.

I took off the wheels and checked the dust shield to see if it might be touching rotors but it’s not. Everything looks fine. I put back on wheels and decided to spray out the area with the hose. It stopped after that so I thought it might have just been brake dust. But it started back again today very lightly.

I can only recreate the noise when making a left turn mostly and if I’m driving straight and I jerk the wheel to the left. Nothing loud but it’s an annoying metallic like whistle.

Since it doesn’t happen stationary I know it has to do with rotational movement.

I used timken bearings inner and outer with new races, greased everything up good, preloaded bearings, backed off then tighten to specs. Rotors and pads were powerstop.

I wiggled the wheel top and bottom and side to side to check for any play and theres nothing to indiciate a problem with the new bearings. And spraying water into rotor, caliper, and brake area stopped the noise right after. 

Maybe the braking hardware and pads don’t have enough grease?
