I'm stripping down the rear beam/diff/arms/hubs etc.. on a 4x4 sierra beam and have not got a socket big enough for the drive shaft nut. Can anyone tell me the size as I measured it up at 40 (i think dont quote me) but went to Halfrauds and they don't go that high but they do an imperial size thats very close to the size I need....

Anyone?

Cheers
Dan
