I have a 03 Dakota that I've had for 6 months.Last night while driving home from work it developed this real schrill noise.Sounded like it came from right front of truck.I noticed it happened at around 60mph.If I took my foot off of gas it would stop.Then I could drive for a mile or so and it would be quiet.It did this off and on the whole way home.Turned off radio and heater controls, had no effect.Outside temp. was around 4 above.If anyone has any ideas what could be causing this I'd like to here your opinions.Thanks

was it a belt slipping?

Checked belt seemed ok.Alternator made some noise,maybe this is where the noise is coming from.Going to take it back to dealer and see if they can figure it out.

It's possible the rear bearing already went out in your alternator.

I have the same prob......Passengers say it sounds like it is coming from the drivers front though. Next time I hear it I am going to turn the OD off and see if engine RPM makes a diff or if is road and/or wind speed.May get dealer to look at it when I get it's next O/L/F.
