None of my nuts were staked. There is an identation and the nut is banged into the indentation, if you follow me?
My old ones were 32mm (have that socket) and new ones are 36mm. I have a 36mm impact socket but it doesn't fit in the wheel hole. However, I think the Laser 6279 thin walled 36mm hub-socket will fit through the wheel. I've ordered one from AllParts and will see if it fits when it arrives next week.
