Hey Steve,
Can't help ya on the socket size!.........................I always used an 18" shifter("crescent" for you sandgropers!) and tighten till your elbow clicks!!!
Burto.
I pulled the rear wheel of a 2011 FXST about a week ago.Something must be different as my torque spec for the rear axle nut is 95-105 ft-lbs. Having said that,the rear axle nut on these things (2011 FXST) are metric. 36 MM.I had to buy an adapter too.I think anything above 32 MM is a 3/4 drive.
