I had the same problem with a Cranbrook.
As mentioned there are two nuts on each inside, one to tighten up the hub, the other to lock it in place.
It takes two wrenches.
Break the two nuts apart, snug up the inside one, hold it in place and torque the other nut to it.
If it is either always too tight or it has slop, you may have toasted the bearings riding it loose for too long.
