Hello there. There is a product from vendors called a nut wacker(?).It is
for the large 46(?)mm hub nut. It is a flat cast iorn piece with a 46mm cut
out,and 1/2 inch sq hole for your breaker bar. Cost about $5.95. Hook this
on the nut, and attach a breaker bar. One is supposed to use a hammer to
hit the cast iorn piece , while applying loosening pressure with on the
bar.It works. Before I loosen the big nut, I file match marks on the hub
and nut.This way, I can retighten to proper torque.
