Tips for removing sleeve off of lower control arm pivot bolt?

Thanks FABO - it worked.
Combination of both, actually: scored the sleeve then banged on it with a hammer. "Slide off" is not exactly how I'd describe it, more like wrestle.

And yes, a lower control arm video would be awesome!
You just didn't hit hard enough. I have a large vice, I rest the pivot with the threaded end in my hand and the smooth end with the sleeve on top of the closed vice, smack it two or three times across the length of the sleeve, and the old piece falls off!
