Does this turbo look ok?
Looking back through the previous owner's records, it looks like this truck ate an air filter at one point. Looks like the turbo was replaced at one point but it's not entirely clear from the records.
After removing the intake parts, cleaning them and cleaning the intake lip of the turbo, I was able to get a photo of the compressor wheel. I'm not sure what the blades are supposed to look like but they are all identical with that little notch taken out of the ends. It spins freely, has no endplay either axial or radial that I can feel. Seems to be in good shape otherwise?

Maybe a prime excuse for a Wicked Wheel.... I guess if it's not rubbing at all, spins well and I can't feel any other movement, I don't need to check it for runout?
I don't have a way to check for that anyway. (excuse to buy new tools!)

No, didn't find any other damage.. but where else would I be looking for more damage?
This doesn't look like a Wicked Wheel... I thought the early 99 engines had the WW? This one looks fairly plain and looking at RiffRaffs website:
Riffraff Diesel: Anti-Surge Compressor Wheel
The WW seems to have overlapping blades. This wheel doesn't? This was possibly a replacement turbo with a later version? Someone else told me this is normal for a non-WW... More research needed I guess.
Oh, and my Chassis is a Jan 99 (on the door jamb) as is the engine (from the left valve cover)

Yeah, that isn't good. That is not an early 99 wheel. If the previous owner replaced the turbo, he had the later compressor put on for sure. If you plan on modding the truck at all, it would be a good time to do the WW, to help with the inevitable surge issues that will come along.

I got a factory replacement when I blew up my e99 turbo and it comes with the non-wicked wheel in it.
I'd be a little leery about just putting a different wheel on. It won't rub now because what did rub is gone. Or you may be alright and can get away with a WW. Just thinking out loud, I just destroyed my turbo as well, at least you have something to work with!!

Thanks Paul, I downloaded that guide a couple of days ago but looking at it now, it really looks like the third example, "dirt ingestion/dusting" Going to look at some of the other guides again for replacement directions. Is it at all possible to replace the wheel while the turbo is still installed?
farmb0y, I also found a receipt in his pile that the filter had been sucked out of the filter housing due to being plugged, and there was some turbo damage. I'm wondering if when this happened, the wheel was replaced with the later model.
Maybe it happened more than once, since this non-stock wheel is showing some erosion too. When I picked it up yesterday, the airbox was filthy, the old filter and intake tube were dirty, particularly after the CCV.
This wheel doesn't have any axial or radial endplay on the shaft and it seems to spin freely and true. I might be able to get away with just replacing the wheel. Any rub it might have had that it clearanced itself, is just more room for the new wheel, right?
I can probably run this one for a while until I'm ready to do the change. Thoughts?

It' only around $50 for a WW. Like you said, put it in and you may be able to get along just fine until you can upgrade or replace.
Many of us do the CCV mod, instead of having the oil and vapor go into your turbo, intercooler and everything associated with it making the mess that you are seeing.
Look for a 6637 air filter too, it's a quick & easy replacement. If the PO was having problems with the air filter and box, the 6637 is a good way to go.

The CCV mod is definitely next on the list, I don't want to have to clean out that intake again. I had to remove it and go medieval on it with simple green and the pressure washer to get the gunk out.
I think the PO was just not doing the maintenance needed for dusty conditions and suffered the price. Twice.
An upgraded filter is way down on the list but it's there. Right now the intake is clean, there's a new filter in there and the box is sealed properly. When it's time to replace that filter, I'll probably jump on the upgrade.
