Well, I'll join in.... I took my swaybar off of my '89 4runner sitting on 31x10.5's, and a friend warned me about how unstable my truck would be in a sudden swerve, lane change, etc. I worried a little about it for a while.... Until I got rear ended by a GMC3500. The impact on my right rear spun my truck around 180 degrees, I crossed oncoming traffic backwards and went down into a ditch and slid along a chain link fence for about 50 ft... I figure if the truck didn't turn over through all of that, it probably isn't going to turn over through any kind of driving that I'll put it through.

In my opinion, the front stabilizer bar is just extra weight on these trucks, and my truck has enough of that already.

I do not think a swaybar keeps a vehicle from actually rolling. I think the intent is to help you retain control of the truck so you do not lose control.

The danger would be over/under steering if you had to swerve, or make some other type of emergency manuver and losing control of your truck. Once you lose directional control of your vehicle on the hiway it is all a crapshoot. You might roll, eat a semi, or just "spin out" on the shoulder.

I think the Jimmy took care of the out of control part in the above example, a sway bar was not going to help much if at all. I have had a simliar incident happen at high speed in a Samurai and did not roll either, we all get lucky from time to time.

The purpose of an anti-sway bar is to keep the body lean down, and to affect the way the vehicle handles (i.e. understeer or oversteer). As it goes into a turn the understeering vehicle wants to keep going straight, so the driver automatically feeds in more steering input. The car that oversteers in a turn will tend to want to turn tighter, forcing the driver to reduce the steering input. Most vehicles in America are set up with a lot of understeer, since it is deemed to be safer by the auto companies. Therefore, removing the front stabilizer bar, which contributes to vehicle understeer, would be deemed unsafe by the auto manufacturers. But many of us (myself included) have added a lot of weight in different areas on the truck, which also has an effect on under/over steer. Then we might have switched out springs, cranked torsion bars, changed wheel backspacing, etc. All of these things affect how the vehicle handles as much, if not more than, the removal of the front stabilizer bar.

So, the general rule is this: Find out how your vehicle drives and handles, and be prepared for it. If you remove the front stabilizer bar and the truck has less understeer (likely), or even slight oversteer (unlikely), learn the way the truck handles and be ready for it. Remember that almost all race cars are set up with oversteer, so oversteer in and of itself is not a bad thing if the driver is prepared.

By the way, my truck with the bumpers, chevy springs, cranked torsion bars, and no front stabilizer bar still has plenty of understeer.

if you have too much oversteer you just have to adjust the steering box. real simple.

I don't understand how adjusting the steering box will have any effect on overstear.
