Rear axles aren't the proper fit, causing them to shake which causes the rotors to vibrate that produces an squeaky/stretching noise when braking. was originally told it was normal until i contacted toyota customer care. service techs states that 'it's safe to drive' but i didn't trust it. my truck isn't the only truck, there are serval more that making this same exact noise. about to turn my truck back in to toyota under the lemon law.
