If you don't know what to expect.....you will have the same result in almost any vehicle. That probably isn't a very good example....sway bar or not, don't deliberately swerve left to right at any speed.
Which is why I suggested that the test be done
at a relatively low speed - you will find out
under controlled conditions what to expect with the sway bar removed.
You may be comfortable with the handling of your vehicle without the sway bar, but are you in control over the circumstances under which it is being operated?
I'd like to share a little story - a true one - that will explain why I feel the way I do, and why I made the suggestion that I did.
A couple of decades back, I had a station wagon on which I was doing some work, and I had removed the sway bar - it didn't
seem to affect the handling significantly, and since I needed to make a short trip (just around 25 miles) on the weekend I figured I would drive it anyway
Three adults and one child in the vehicle, I was overtaking a slower moving truck on a two lane road, doing maybe 45 mph, and I had to make some sort of evasive maneuver, I don't recall why, but I do recall the result - the wagon swayed wildly back and forth, and it was by the grace of God that I did not lose control and end up under the wheels of the truck.
As a result of that incident I DO know what to expect with & without the sway bar - and I WILL NOT operate a vehicle at highway speeds with the sway bar removed.
Also for what it's worth - over the years I have routinely done that left/right/left swerve (except that since we drive on the left here it's actually a right/left/right) - you don't have to saw the wheel back and forth, just rock it - it does a couple of things, I can judge the condition of the steering, the suspension and the wheel bearings all at one go.
Now - tell me - are you operating that vehicle without the sway bar on the public thoroughfare? And if the answer is yes - please also tell me which state you are in - so I can stay out of your way, because heaven forbid you need to take any sort of evasive action at any reasonable speed - I'd much rather myself and family not be in the immediate vicinity.
Anyone else wants advice on removing the swaybar - I invite you to try that little test, and when you're done, and you know how the vehicle will react, think about the vehicle's normal role - Is it a daily driver? will it see highway (high speed) use? Will you be the only driver? At the end you'll be able to make your own,
informed decision.
