Live in the chicagoland burbs.
Specifically where the recently new(5 years) drive way meets the
garage concrete. The divider or filling (not sure what to call it) is
in pretty bad shape. Looks to me like water is getting under the
drive way and freezing. Has not cracked, just risen about 2 inches.
Is it difficult to replace this? Where would you find it?
Replace what? The concrete?
If so, break up and remove the old concrete, build a form, fill with rebar,
and have concrete delivered. Easier said than done.
Or, wait until the concrete slab settles back down (after the winter) and
replace / re-seal the areas where excessive water gets beneath the slab.

I have had the same problem for 23 years. I have a surface aquifer that
runs under the driveway.
The asphalt rises about 1" all along the length of the double door
garage concrete apron.
It's too cold to try to fix it in the winter, and in the summer it fixes
itself, so I don't have to.
Water is very good at getting through almost any thing you try to seal
it with. Freeze thaw and it will make just enough of a new crack to let
more water back down again. The only solution is just like a home, provide
a way for the water to get out of there. It is all about the foundation.
Of course the alternative is to put the foundation down below the frost
line, which likely the garage is but the drive is not.
