No problemo.
My Spicer Pro Grades were the same as the originals.. lower was smaller(1 1/8" sounds right) and the upper was definitely 1 5/16"... remember that since I had to specially buy that socket.
The part number for the Snap On spindle nut socket is S8695C, you can find it on their website here. I don't own this one yet, but I do have the one Shucks/Orriellys/Kragen/CSK/whatever sells and after a few uses the prongs are starting to bend. The extra $40 is worth it.. I just haven't ordered it yet.
What I ended up doing is buying HF's impact socket set and the 1 5/16's socket from Kragen.
I don't know if your going to run bigger tires or not, but the bigger you go the more you have to figure on doing them more frequently. With stock sized tires and Spicer Pro Grade balljoints I think you could easily expect them to last as long as stock, if not longer.
You should repack your wheel bearings fairly regularly.. hence why I'm going to invest in the snap on tool.
No salt here but moisture gets into everything. When I did the 89's wheel bearings, I found them packed full of a mix of greasy mud
