I don't know how to tell if it's a cheap Chinese rebuild or not.
I don't think it's a rebuild; I think it's a whole new Chinese turbo. The numbers match the listings in the two links I gave, which say "Origin: China" and "Country of Origin: Jiangsu China (Mainland)".

How does the shaft feel?
Does it spin freely?
Do the blades rub against the housing?
Any forward-back, side to side shaft play?
The play is barely noticeable (I really have no experience with turbos, but it feels like others on here have described it should feel). No blades rubbing or anything like that.

My factory turbo has always been kinda quiet. More like a soft, distant whistle.

Those Chinese turbos fail because they are either not balanced, or not balanced correctly. That is most likely the source of the whine, but even the factory turbos are super quiet.
It doesn't seem abnormally loud or anything, just not the type of sound I'd expect from a turbo.
I'm not concerned about it right now, but I've heard a lot of talk about these being ticking timebombs. I was just wondering since I have like half the engine apart now and the turbo just sitting on the workbench, whether I should put this turbo back in or get a legit Garrett one. From the responses so far I think I'll just stick with this one and try to keep an eye on shaft play every oil change or so.

If it was a genuine garrett, it would have GARRETT in raised letters cast into the intake side. Also garrett uses tags that are riveted onto the centersection to id the turbo. However some factory turbos do have a machined, flat area that is then "dot punched" to label it, but the lettering is far smaller since it not only lists garretts part # and serial #, but also the oe # for whoever the turbo was produced for.
Id be willing to bet its chinease made, its for sure NOT a garrett!
I agree. It doesn't say GARRETT anywhere on the thing and the label in the flat area is definitely laser engraved rather than dot punched. Kind of unrelated, but the serial number begins with 140609, which I suspect may be the date code.
