there is also a humming/whistle/ rubbing noise can't really describe it its like a rotational hum. i can't tell if it is comming from the brakes or maybe the diff. the calipers rn't sticking put it on the lift and started it up and let the rear tires spin in 1st and then took it out of gear and let it spin as well as hit the brakes and they released fine i just can't figure out the noise.

Bearings? Is your diff getting hot and the heat is transferring through your axles? I know it sounds far fetched but if everything checks out.....

so just drive it & feel the diff cover? I really can only put that noise to be comming fRom the diff cuz even when I apply the brakes the noise is still there until im going less than like 10-15 mph. seems almost like the noise would have to be the diff. my diff seal is leaking but don't see why that would make the noise.
