I replaced my driver's side CV axle last week. There is an excellent video teaching the procedure step-by-step at Youtube. It helped me a lot. He jacked up the driver side side rail used to change tire and only half quart of transmission fluid spilled out during the procedure, because I think he tilted the transmission away from the axle opening on the transmission. I was thinking to jack up this point, but I was afraid that my car may flip over. Instead, I jacked up the regular front jacking point where a hook is attached to the frame. It was more stable. However, I lost lots of transmission fluid: 4 quarts. It's O.K. because it's almost time to change trans fluid. But my concern is the correct jacking point. I understand that side rail of the vehicle next to the wheel well meant for tire change only. Is this safe to use this jacking point for other purpose like suspension or powertrain repair?
