However, when putting it into 4WD the noise stops. Any ideas on what this could be?

This sounds like you need to check the rear U joints for wear, or you have a transfer case that needs to be rebuilt or is low on fluid. If you upload a short video of the problem, I could tell for sure what's going on. Here is how you can remove the drive shaft to check the U joints:
