Just re-read your post and looked closely at your photos. You have the crossbars cranked up to the max - that's why the car is "top heavy". You have to lower the car with the threaded rods at each end.

You use the threaded rods to adjust "balance" ONLY. The working height is adjusted using the hydraulic jacks and the pivot heights at each end MUST be the same. When adjusting working height, imagine the car spun on its side ... the pivot height will be the driveshaft tunnel height.
