Front axle playing skrillex music

Climbing up a bank, as soon as the front right wheel (from in car) touched the incline, something started squealing like crazy. I thought it was wheel bearings. When i parked up, i kicked the wheel, to check for side-to-side movement, and it looked like there was, but i think it could have just been the tyre.
So the next day, when i had some daylight, i took the front wheel off, having chocked the wheels and put it on axle stands, and i couldn't see anything wrong with it. No hub play, throughout a full 360 degrees, there was nothing caught on the disc, so i fired up the engine, put in in gear and let it run, and then came the very, very loud crashing and banging sounds from the front axle. I personally do not have the slightest clue as to what this could be other than diff or half shafts. Greased the prop, no difference, also tried slowing down the hub by putting the pads back in, to make sure it wasn't just slop, the noise was still there. There's something broken I'm sure. Any suggestions?

Strip down only way to know for sure.First remove the drive flange on each side and turn the half shaft stub by hand ,you may feel if something is rough.Could be CV on the way out or as you say diff/half shaft, or the drive flange its self.

you need to check wheel bearings with wheel on and jacked up ,plus then you can turn it to feel for issues in full lock as well on both sides,best with just one wheel up

Good suggestions. I'll get on that tomorrow, Thanks
