Taking apart the passenger side CV axle revealed some nice gouges on the inner race. Only 1 out of 6 balls had a flea sized flake missing and I guess this is the result. No real tech, but thought I'd share the damage a tiny metal flake can cause. Hopefully these can be purchased a la carte.

Can you give us a little more color ie... miles, age, amount and color of lube, was boot leaking, any containment inside boot and how got in (other than flake), what/why symptoms for pulling CV..ect..

177K, no issues other than leaking clamps which worsened after 1.5" OME lift. The boots were in good shape, but I had no idea if the PO ever had these serviced. Figured I'd tear 'em apart for a good cleaning/re-lubing. Also the old grease was semi-runny and kind of a chocolate milk color.
Any ring on the opposite side, inside the bell?
I think you would be better off with a new (or complete) unit as you can't trust any of the parts in contact with those damaged balls. I wouldn't mix and match if it were me.

You're probably right about the mixing and matching.
So it's around $400 for an OEM unit or $109 for a new, lifetime warranty from NAPA. I'd rather get OEM, but and I'm tired of spending money I can get the NAPA unit today.
Any thoughts or experience on this?
I agree, new for longevity.
For serious off-roading I think a used OEM is generally preferred to a new NAPA but a warranty is a warranty. I think the consensus here is that they are different.
They're not even close in design. We use the large balls with heavy hardware and the NAPA one uses what looks like cartridge bearings. For mall use, the NAPA may work but for off road they've been proven to fail. I don't think anyone who does trail time is running them.
Don't do it, unless you want to use that Lifetime Warranty early and often. They're not the same.
The Napa units may be great for street use only. However a lot of members have installed Napa units, and have had vibrations, boot failures, and breakages. Time is money, I'd hate to see a member pay to have a Napa unit installed and then have to go back and spent more money on installing a OEM CV + labor.
The Napa CV's use a tri-pod style internals. Whereas OEM is very similar to a birfeild.

You can edit your original post so as not to post 3 back to back to back with one or two words. Keeps a cleaner thread.
HaHa, how could you replace big balls and heavy hardware with anything less?
I'm keeping my big balls and heavy hardware 'till the end!
Well said.
This has gone around too and other than rebooting I'm not aware of any reman OE CVs. New is probably your best, with keeping that as a trail spare. If you don't want it, I'm sure you can sell it very quickly (for a price consistent with its condition) to someone else as a spare. IIRC new are around $400.
Wasn't intended, but that's pretty funny in retrospect.
Napa = Tripod = Bad for high angles.
OEM = Rzeppa = Handles angles better.

Since the originals lasted 177k, the $400 you spend on a new one is likely to be considered "lifetime" either way. Going OEM means you probably won't have to worry about it again.
