but when I apply the breaks I don't hear that screeching sound. This usually happens when I'm moving at 60MPH or more. Any idea of what wrong?

Thanks

 

could be a brake pad, either draging on the rotor or wore out.
maybe a wheel bearing.

i would start pulling rims off to inspect the brake areas..

 

could be your speedo cable but it wouldnt be a wretched screeching more like a squeek..squeek..squeek..squeek..squeek..squeek..squeek..squeek.. and at 60 it would be pretty loud...ive taken mine out and lubed the **** out of it 4 times and it still squeeks....

 

That is the "audible wear sensors", telling you that you need brake pads. Little tabs of metal whose sole job is to alert the driver that there's something wrong with the brakes.

Do a brake job on the front.

 

Thanks for everyone's advice :hail:
