2004 D2, knocking while coasting, normal under power. It does it in hi, low, locked transfer case, and unlocked. I dropped the front shaft, took it for a spin, and the noise is gone. I?ve always thought that the driveshaft noise was more of a chirping than a knock. Should I be looking at the front diff instead? I?ve driven it for a week now without the shat with no noise, would a diff noise go away with the shaft driving it?

I had a bad driveline vibration when I first got mine, it was 3 years old, around 100,000km. It was okay under load but quite bad neutral throttle (no load), accel or decel and it went away, most pronounced at highway speeds. It turned out the front diff pinion nut had backed off, re-tourqued it and never had another problem. Noise was gone without the driveshaft.
