I have an 06 1500 and for the last few months i have heard a tinging sound from passenager rear end. Ive taking to one place they told me i needed a new belt and i laughed at them. Ive taken to a new place last week and he said that a brake line is bent and it might be causing the parking brake to rub. The sound is only while in motion. I started hearing it after i replaced the shocks... I was thinking it could be shocks are bad, bushings, body mounts, wheel baring, If anyone can help it would be awesome.
