Doesn't that pic look like the hub already has a repair sleeve on it or is it my eyes? He could just remove and replace the repair sleeve.

Yes it does. Initially I didn't even look at the pic.

Don't know about the cost, but the repair sleeves are available at most auto parts places.

It's hard to judge from a picture. It does not look all that bad, but if it was real cheap, I'd probably replace it. Your call.

Save yourself some grief and replace it, it's apart, IMO when in doubt swap it out it's cheap enough and will be one less thing to worry about.

Hey, good pictures also!
