I would take 7 thou off the shaft myself. That's basically one light cut with a sharp lathe tool. A tool post grinder would be ideal, but since it doesn't have to be smooth (you're sleeving it, after all) a regular lathe tool is fine. I'd probably center the work in a 4-jaw chuck using a dial indicator, make sure the tool touched lightly all across the sleeve area, then go in 3 thou in one pass. Trying to take off less than that often makes things worse rather than better in my experience. Then mike it and if it's above 2.168, use roll emery cloth wrapped around while the lathe is running to pare it down a little more. I did this on an axle for a mucker a few years ago. If you try to stretch a sleeve past its recommended diameter, it's liable to split open.
Another option that often works, if you can get at the seal, is to change to a different brand of seal or a thinner or thicker seal that will run in a different spot on the shaft. Sometimes two thin seals will fit in the space for one original seal. Seals are cheap so that can be a way to space a seal out so that at least one runs on a good section of shaft.
