Weird buzzing sound

good morning everyone I have a weird buzzing sound it sounds like it's coming from the front right side of my truck 2007 TRD. it sounds like a buzzing/rattling it's not more when I accelerate or when the heats on it's just there what the hell is it? I am always so grateful for your input thanks very much

 

When is it buzzing?? When shut off? Only when moving ? etc.

 

when I'm driving...it only happens like once or twice a week...almost sounds like something is rubbing but I'm my exactly sure...it stops after a few miles if driving

 

I know it's a very broad question But any suggestions would help...also the right front side vears quite a bit but the wear is even on all tires...maybe that has something to do with it ?

 

OK - A few suggestions ....

- Brake pads not returning (Calipers sticking) causing dragging of the brake pad to the rotors.
- Low brake pad and wear warning tabs are hitting the rotor (needs brake pads replaced).
- Since it just got cold - I had a car that had vacuum lines that were old and / or oil soaked. Sometimes the connections would leak and whistle.
- Pull the cabin air filter behind the glove box and look for debris that my be hitting the fan
- possibility of the cat heat shields loose /hitting the drive shaft?

When you hear the noise
- use your brakes and see if the noise changes?
- does the noise change when you change speed?
- slow slowly to a rolling stop if you can and see if the noise stops when the vehicle stops
- changing fan speed changes the noise?
- will it happen when only cold out / only when you first drive the vehicle - or only after it has been driven a number of miles?

 

thank you appreciate it !!!!
