notice a cracking/creeking noise coming from rear wheels. Starts happening after about 20 minutes and usually is noticable when i turn slightly at low speeds. Its not tire rub or a clearance issue, ive checking all around the wheel both on and off the lift. Watched it from outside the car in the driveway and when it cracks the wheel adjusts and vibrates quickly (see the whole tire shake) when it makes the noise. Happens on both drivers and pass wheels. I am thinking something with the drum brakes. Seems like the wheels are fighting to rotate and are beaking free of something holding them back when the noise occurs. But then why does it only happen when turning at low speeds and only after about 20 min of driving. Torqued all lugs down to spec today, still happening. Help!!
