If the sway is NOT dissconnected during the install, it is possible for the endlinks to rotate past center then stay in that position while reassembling the front end. If the sway bar endlinks are dissconnected before installing the spacers and then reconnected after the everything is put together, it is nearly impossible to re connect the swaybar like that. There is a very easy solution, use a floor jack and (although it seems primative) just lift up on the end of the sway bar and it will "pop" the bar into the correct position, it takes a bit of force, but it will go. And since the sway bar is just a big spring, it wont damage anything. Yes this has happened a few times, the very first time i took my own front end apart, fo instance. But please note the position of the sway bar before starting the installation and it will look just like that after the install.
