You'll know it if you have it. Get under your truck and grab the driver's side CV axle where it goes into your front diff. Now move it, up/down and back/front. There will be alot of play. Try moving it in/out, more play. Now compare it with your passenger side CV. There will not be any play, it is nice and tight there.
Best advice I can give you is to find a freshly paved street, as these tend to be the quietest and smoothest. If you are listening, you can hear what I can only describe as a vibration, like if you had mud terrain tires. I can actually feel it when I have the stereo on.
Switch into 4hi when you hear/feel it. It will instantly go away as soon as the diff engages. You won't hear it, you won't feel it. Go back to 2hi, it won't be instant, but as soon as you let off the gas and take the tension off the CV axles, it will be back.
