I have a 2005 SXT AWD with 66,000 miles. When the car is cold, I start it up, put it in gear, and when I begin to move forward while turning the wheel, it gives out this low rumbling vibration. The tighter the radius turn, the more extreme the vibration. It feels like it is coming from the rear, but I can't be sure. It all goes away when the car warms up, and all systems function normally. Any ideas?

 

Ck the driveshaft bolts, one maybe loose or missing.
