So the sound is more like a stone stuck in tread. Started awhile ago thinking is was a stone, but till there. 26k on truck and today I tried something while driving. Going about 40 mph, window down, I rotated the steering wheel L/R and noise went away briefly then came back. Have not jacked up that side to check for possible;e bad bearing/hub, as I really thought it is the squeal thingy on brake pads indicating they are low. BUT seeing how the noise went away w/ the L/R motion has me thinking it's not the brakes. Thoughts?
