Aside from the boots to keep corrosion and abrasives out, you can try to pull the cv shafts and get grease on the splines. That would be your 2nd best way to mitigate this before it becomes a full issue. Beware, the cv seems to like to seize to the shafts pretty good. In my case anyways. So I rendered the cv shafts junk when I pulled them off from all the beating. If that happens it's likely the drivers side stub shaft will come out still attached to the CV. I didn't attempt to soak them in penetrating oil prior to disassembly so that could possibly help. But unfortunately it can snowball very quickly. At the minimum I would have both cv replacements as well as the driver side stub shaft on hand to be safe. Best case you can return them if it comes apart. But I would much rather forewarn you of the aggravation before you spend all day tracking down parts in stock or else your rendered truck less.
Side note, I live in NJ and my truck spent most of its life as a tree service vehicle offroad and in the rust belt so I do believe that accelerated this issue, but it is a poor design that will eventually fail, just a matter of when.
