Last time I did this job I went through all the gyrations with 10'
pipes, torches, sledge hammers, etc. until I bashed the lip of the
fender (this was on my '68 to get the brake drums off) and finally gave
up and rented a 3/4 drive electric impact driver.  Still took several
seconds of impacting to break loose.

The problem is that the inflated tire absorbs much of the force when you
try to break these nuts loose or tighten them by hand.

You really can't over torque these things when reinstalling, so just
impact away with the driver.  You just need to be sure to line up the
castellated nut with the hole for the cotter key.

A trip to the rental store will save you much aggravation for about $25,
and the 1 13/16 socket (which you also rent, they are at least $15 to
buy a good one) is close enough.

Your van will thank you!
