When you jack the car up, and spin the tires by hand, do you hear the noise?
What speed do you star hearing the noise?
A caliper dragging would heat up the rotor and the rim, you can touch the rim after a long drive and see if one is hotter than another.
The piston on a dragging caliper is usually harder to push back also.
Did you clean and lubed the caliper slider pins?
There is vibration, but it's separate from this and happens between 65-80 MPH. Think I figured that one out, both forward control arm bushings are shot...arms twist about an inch in either direction.
Tires seem good...owner is replacing one of them (passenger rear) soon. If I let go of the gas, the noise is still there. Pressing the brakes lightly (pedal down about 4-5mm, could just be the pedal play), it's still there...once the brakes noticeably start to slow down the car it disappears. That makes me thing it's not related to tires/
When I spin the tires I don't hear the noise (used to be noisy before I replaced the hub assemblies). Noise is noticeable at about 15 MPH, and frequency goes up with speed.
I did check the rim to see if it was hotter (I think the noise is coming from the passenger front), and nothing was out of place. I'll double check on Tuesday (I'm doing all four control arms then).
You know, both pistons were harder to push back than I anticipated, but I chalked that up to my tool not being seated properly (I have the Lisle pad spreader tool and I was pushing at an angle). I did lube up the slide pins.
