I replaced mine last year. I also found one link was broken like yours. However I didn't notice any effect on the handling on the highway!
You don't have to jack the car up. You only need to raise the EAS to have a bit more working room to slacken the nuts off.
Then put the EAS back to normal ride height to knock the links out - the bolts in the sway bar links only line up with the holes when at normal ride height.
I am in the process of making detachable sway bar links for off road use. The links have to be disconnected/reconnected at normal ride height.
