I would suspect (#1) If yours is a 4WD, check the level of the lubricant in the differential. (#2) If it is 2WD, you may have a wheel bearing going bad.
In order to tell you that you would have to describe the noise and what the car is doing when the noise is made. Are you idling, driving, just turned the AC on? What is occurring and what is the noise? Idling and sounds worse when AC is on. Sounds like it is coming from the top of the engine. Vehicle has 120k miles
Ford Dealer can help you. And tell you if there is anything wrong with your 2003 F150.
If the noise is a squeaking sound, it could be coming from the bearings in the blower fan. It could also be coming from a worn bushing or bearing in the blower motor.

Take it to a garage!
Not enough info. What kind of noise? Coming from where? Under what situation(s) does it occur?
heat/ac actuator
Sounds like a wheel bearing to me.
Questioner gives no indication where the noise is coming from, but it COULD be an indication of a failing CV (constant velocity) joint.
A squeaking noise coming from the glove box on a 2003 Dodge Ram might be the heater blower fan. Try oiling the fan to see if it will stop. It could also mean that a screw is missing from the dash and the squeaking noise is the dash moving a little in that area.
Are you sure the noise isn't in the front. Sounds like a right front wheel bearing,which is a common problem on these vans.
