Ok so my truck began squeaking at speeds above 62.5mph about a year ago. Took it to a dealer and they replaced my passenger side hub. Squeak gone...so I thought it came back and I replaced my driver side hub...squeak is still there. I am at a loss at this point, I can't seem to find the origin of this sound. Above 62 you begin to hear a squeak, squeak the faster you drive the faster and louder the sound becomes. No vibration and you can't hear it below 60.
