Dually brake drum removal

[FLATBEDFORD]

Does anybody know if the drum and hub are one piece on the dana 70 DRW rear? If yes, what size socket for the bearing lock nut?

[Leadfoot]

Depends on the year some some have tabs and some take a special thin wall socket and there is two sizes also all are available at you auto parts store they cost around $20
also you can take the wheel bearing hub off the drum but only when off the truck.

my 1970 and '69 both take the 2-9/16"6R socket UAP/ napa Ultra Pro pt# 62833

I read the label on the package and bought the one for my truck, 2-3/8. I exchanged it for the correct one, 2-9/16 as Leadfoot said. Thanks Leadfoot.
