8.75 SureGrip , Is this Normal?

If you turn a suregrip round with only one shaft in the axle, the splines in the suregrip unit will be misaligned so when you put the other shaft in it wont bottom out/fully seat the way it is supposed too. It is possible thats what happened. Both shafts should slip in and fully seat without force. To align them again you will have to put one axle in fully seated. You will then have to put the other shaft in as far as it will go and then use a pry bar and turn that shaft and push it in at the same time. This takes some strong force. I've done it. Let me know if you dont understand.
