There is a combination socket that I use for Budd style wheels- - - -one end fits the 1 1/2" outer nuts, and it flips over for the square inner nuts. It's 3/4" drive. I got mine at a NAPA parts store. I'll see if I can find a part number in their online catalog. I believe the square shank on the inner nut is either 3/4" or 7/8", don't remember which without measuring one.

Wrong!

It's a 13/16" square shank, and here's the combination socket:
