I have a 2006 530xi (E60). I plan on supporting the rear end of the car with a jack stand under each of the rear jack points i.e., one jack stand on each side by the rocker panels. I'm looking for the best place to lift the entire rear end of the car from a single point using a floor jack. There seems to be some online dispute regarding if it is safe to lift the car by the differential, the key issue being risk of damage to the differential or any connecting linkages. There is a cross support bar just behind the differential that may be a good lift point for a floor jack (please click on the attached image which includes some mark ups). I would appreciate anyone to chime in with what single point is the best place to put the floor jack to lift the entire rear end of the car. Is it okay to put the jack under: The cross support bar? The differential? Neither? Or both? Thank you in advance.
