- Chock both rear wheels. You also have a wheel chock in the back of your trunk
- Use factory jack, or another floor jack preferably, to lift up the front end slightly, just enough to get a jack + wood under the car. This can also be accomplished by driving the car on a 2x4, or even ramps.
- Place a block of wood on the jack to distribute weight, put it directly under the frame rail. You'll know what it is when you see it, it runs most of the length of the vehicle. There is one on each side.
- Jack to desired height
- Place jack stand under rubber jack point
- Lower car onto jack stand
- Repeat on other side
- Chock both front wheels
- Look for large U-brace in front of differential
- Place a block of wood, or a rubber pad of some sort, onto jack
- Jack directly on U-brace to desired height
- Place jack stands under factory rubber jack points
- Slowly lower onto jack stands
Getting the car off jack stands is the reverse of the above.
I've done this many times and have had no damage whatsoever. Nothing is bent, everything is good, and I've inspected them thoroughly to make sure. The car can be supported by those frame rails. In fact, the Bentley manual mentions those as valid safe jack points in a few places. Remember, weight distribution is important. It is not ideal to have all the weight on one part of the rail, even though I am sure it can support it. A big block of wood to distribute it is always best.
