I respectfully disagree with this info. Changing out the shocks in the rear for longer shocks will allow the Pathfinder to fully flex with the rear sway bar in place. No sway bar and 4-link = no-no (see DEATH WOBBLE).
I removed my front sway bar a long time ago, because I kept breaking the center mounts. You'll probably want to stiffen up the front end to compensate, or she'll lean heavily into and out of turns, which greatly affects cornering agility.
I've done two things to compensate. First, I had stiff valving installed on my front shocks (but any stiff shock will do). Second, I adjusted the second stage of my 2-stage torsion bars so that I was just sitting on the "stiff" stage. This helps tremendously with body roll around corners.
Obviously, without adjustable shocks and 2-stage torsion bars, you're gonna have a sloppy ride when going any direction but straight. But try it...worst case you can put it back on!
