I go to tighten it down and when i twist on the nut, it spins the whole shaft and you can see the outer plate on the slipper pad turning with it. What am I doing wrong here? Any chance it might be the diff instead. It is fine holding the car up in the air, but as soon as you put it on the ground it really will not go anywhere? What is th edeal?
