The front anti-sway bar is attached towards the center with a 13mm nut-and-bolt combination that will tend to spin freely as a pair unless you prevent that with a 13mm wrench at each end.

The front anti-sway bar is attached towards the outside with a 17mm nut-and-bolt combination that will also tend to spin freely as a pair unless you prevent that with a 17mm wrench at each end. This is more tricky. For the outbound wrench position you might well need to shove the rubber cover out of the way so that you can get the 17mm wrench into position.

There are two places at each end where you can remove the 17mm attachment, either towards the top or towards the bottom.
