I always suggest to people to disconnect the swaybar and take it for a drive. Every Jeep is different. Some drivers are OK without it off and others get nervous because it feels too loose and unstable. It does take some getting used to especially with a flexy suspension.
I remove my swaybar for the summer. I run the soft top and I do get a little bump steer but it never goes crazy.It's actually really nice running on highways. I put the swaybar back on in the winter when I put the hardtop back on. The higher center of gravity from the top gives me way to much body lean in corners. I have a set of disconnects on it so I can disconnect it for wheeling. I also put the swaybar on when I pull my utility trailer.
