It wasn't safety that I am concerned about and lifting from the diff and placing stands is probably the fastest and safest method. It's overstressing the little rubber diff mounts that worries me more. I think it's the E46's that get all kinds of noise issues when those rubbers get even a little bit of wear or degradation. Those mounts are designed only to hold the diff in place as quietly as possible and lifting the whole weight of the car with them doesn't seem like a good idea. Not saying that anyone would ever notice the difference just my opinion.
