I have a ram 1500 quad 4x4. There has been a squeaky noise like when your brakes are going bad coming from the rear of the truck. You can hear it all the way up until about 30 mph then it goes away. Does anyone have a clue what this might be?

 

no idea. but if you find out lemme know cause mine is doin the same and i have new pads and rotors all the way around. getting really annoying

 

I'd look at u-joints and bearings. For me cleaning the brake pads with sandpaper did the trick

 

recently have rear brakes done? i usually always put disc brake quiet on all my pad linings.

 

Back brakes do have a little squeak to them, might have to try some Disc Brake Quiet
