I have a 98 f150 and it just started making a chirping noise coming from the drivers side front tire area. It doesn't do it when idling just when I get to about then just gets louder the faster I go. It sounds like a bird in there and is really annoying any help is appreciated. Thanks

 

Is it speed-dependent or rpm-dependent? In other words, is it coming from the engine or the chassis?

If it's from the chassis, about the only thing I could think of would be a brake pad/caliper issue. Doesn't sound like a wheel bearing-type noise.

 

Cat heat shield. Spot welds break eventually, then chirps like an annoying bird.

 

I'm thinking either brakes or bearing. My buddys a mechanic and he said it could be a bearing its not as likely as other things but it could be

 

Follwing. My truck makes the same noise. Definitely speed dependent not rpm dependent.

 

Mines speed dependent too

 

try a new belt...

 

I thought about that to but it doesn't sound like its near the belt it sounds like it in the tire or brakes

 

For once I got lucky and it was an easy fix there was a rock between the rotor and the dust shield

 

Sweet !!
