when you get ready to fix anything I'll walk you thru
yes the woo woo woo sounds like warped rotors..laying it flat on a table won't tell you anything, you need a micrometer and a lathe to check lateral runout , a warped front rotor you should be able to feel it in the steering wheel, it'll shake back and forth, rear disk or drum warpage will be felt more in the seat like a thumping.
You can check the calipers as stated above, to check for drag, but also place your hand on the lower control arm to feel for any possible bearing vibration, grab the wheel with your hands at top and bottom while it's still bolted on, and shake it like your trying to wiggle it loose, that method will be checking both ball joints, roll the wheel 90* so your hands are left and right and repeat wiggle to check inner and out tie rods, you can check the sway links, and struts by lifting on the wheel with both hands...
Your problem could be one or more of several things, binding caliper, internally broken hose on either side (which would create a flapper valve), and brearings can cause a pull, also ball joints
get the car up and take pictures, or tell me where you're located and I can send you to one of my shop for a free visual inspection
