Sorry I'm a newbie, I maybe using the wrong words. On the other guys cars at the track you can push the car on the front wheels holding the backend up and the drive shaft turns. When doing the same on mine the drive shaft does not turn, theres no friction at all. When the front diff box is taken apart and I turn the front wheels the gear doesnt turn at all until you turn the back wheels. But if I push in on the cvd arms puttin pressure on the fron diff, and turn the front wheels it while lock and cause the gear to turn. Any help is appreciated.
