Question about what's loose in my rear hub

[Jasper7821]

I wrecked my car last year and took a few months and put it all together and it's been fine for months. In the past few weeks, when I turn right I can hear just a tiny bit of grinding and sounds like when pads are worn and metal to rotor sound. I took my wheel off today and as soon as I took the caliper off I noticed the hub could wobble in the hub carrier. I haven't dug into it further yet, I need to take the axle nut off and the hub to see what it is. Only thing I can think of so far is the axle shaft. Instead of buying a new OEM or good used OEM, I bought this new cheap one. It worked fine for months, but also seemed to slowly develop backlash. After the car was warmed up it seemed that when you give it gas or let off, it clunked like it's developing play in the axle.
Then the last few weeks, this grinding sounds.
Hoping it's the axle shaft as it has a full warranty.
Any advice would be greatly appreciated.

Here's a link to the quick video of the wobbling.
