According to the diagram shown ealier, if you wanted to lift the back side of the car it says to use the differential (3) as a jacking point, however I noticed that there is a beam (black in color) that runs side ways. Tried jacking the whole back side using the beam and it came up without any issues. Has anyone tried this? Am I at risk of damaging something in doing so? The reason I don't want to use the differential is that my jack won't reach all the way past the cover. Thanks!
