The castellated nut holding the hub to the axle shaft is supposed to be torqued to a minimum of 142 ft/lbs. Mine was finger tight, if it weren't for the cotter pin I suspect the nut would have come off. Remember the trick I mentioned above for loosening the hub without a puller? Well that is essentially what happened here. I was able to back the nut off as in the video, put the tires back on and put her on the ground. I then pushed the back of the car sideways several times and you could see the hubs pop loose. I suspect if it weren't for the cotter pin the hub would have come off and the tire with it causing major damage.
