Have you visually checked the new units to see if there is anything causing this, ie 'blocks' which are loacted in the springs for when cars are in transit, which should be removed by the dealer.... wouldn't expect this on a new set of replacement suspension but ya never know... plus, having seen the very same issue on another car (different forum) and it was this reason why the car looked jacked up, its the 1st thing that sprung to mind.
