How do I remove a BMW 320I Driveline?

1. Park the 320 somewhere flat and out of traffic. Make sure the emergency brake is pulled before you turn the car off. Jack up all the front end, and then lower the front end onto jack stands. Then, jack up the rear end, and support it on jack stands, as well.
2. Go underneath the 320 and find the driveline. Look for a metal tube that runs between the transmission rear and the rear differential. The tube will have two rubber boots over the continuous velocity joints. The metal flange on the bottom of the boots is what anchors the driveline to the other powertrain components.
3. Slide the car jack under the car and jack it up so it touches the transmission side of the driveline. Then, unbolt the six bolts that secure the driveline to the transmission. Do not lay directly under the driveline in case it falls off the car jack. It is heavier than it looks. Lower that end of the driveline down with the car jack and then go to the differential side.
4. Raise the car jack up so that it supports the differential end of the driveline. Then unbolt he six bolts that secure the driveline to the rear differential. Use the car jack to lower the driveline down. Pull the driveline out from under the 320. You can lower the 320 off the stands at this point but it will not be drivable until the driveline is replaced. You can push the car around if you disengage the emergency brake, though.
