This just started yesterday with my 2001 Sonoma SLE. Seems to get worse when I'm crusing along and then take my foot off of the gas. Like you, putting it in/out of 4WD temporarily quiets the problem, and sometimes it's gone completely.

Your post was back in Jan, so I'm assuming you figured it out and got it fixed by now... What was the issue?
