The locking on this hub design is a strange one. Take a look at it (if you want!) - there is only positive locking between the nut and the hub there is no positive locking with the trailing arm => it looks to me like it all holds together because it is so super tight and that's because you are deforming the crush sleeve when you install it. If it isn't tight enough then it will probably start to come loose - which I guess by most standards is considered to be dangerous!
