Hello,

I pushed the 4 wheel button and had no problem. About 30 seconds into the drive I heard and felt a loud clunk. 4 wheel seemed to be working fine. I turned the 4 wheel off to make a sharp turn then back on again and the truck shook while I was driving for a few seconds then stopped. 4 wheel seemed to be working. I later shifted out of 4wheel for dry pavement. To test to see if it would shake again I tried to shift again while on dry pavement. This time the truck shook for a few blocks and I couldn't tell if it had shifted into 4 wheel.

Chances are you have a bad universal joint on the front drive shaft. Check that. If they are tight, check CV joints. Because it vibrates, my guess is a bad u-joint.

Let me know what you find.
