I'm getting a shutter when I'm at a low speed and turning. At first, I thought it was u-joint in front, but they seem fine. I jacked rear up and put it in gear and no noise from rear differential. Only happens after I've been driving 10 15 miles. When I'm cruising it doesn't do it. Only from a stop making a turn. Get above 10-15 MPH goes away. Changed rear differential fluid out of caution. Fluid looked as expected for 50000. Shakes whole truck.

Hi,

Are you certain it isn't in 4wd? There have been a couple of technical service bulletins related to the front hubs not engaging or disengaging. Do you have manual hubs or are they operated with vacuum?

Let me know.
