I have an 04 dodge ram. I have recently encountered a chirping noise at low speed (it may be there at higher speed, but I can’t hear it over the engine). It sounds like rubber, rubbing against itself or birds underneath the truck. The noise speeds up and gets a bit louder as I accelerate. The sound generally goes away or I can’t hear it after 25-30 mph. This only happens when in motion, so I don’t think it’s the belts. I’ve read a number of things from CV Joints to Bushings and not sure if it’s either. Any suggestions would be greatly appreciated.
