Within the first 2,000 miles, my truck had a drivetrain thunk when stopping and starting. You could feel it in the seat and it was very noticeable. It took three tries with a needle-equipped grease gun on the front and rear driveshaft spline boots, but the problem is now gone at 4,000 miles. Also, around 2,000 miles, the truck developed a loud thump in the front suspension during low-speed full-lock left turns, as during parking. This time, it took two tries with a grease gun on the upper ball joint grease fittings, and that problem has also been resolved. I really wonder if my truck is the exception, or is DC saving 25 cents per truck by cutting back on factory grease. I just hope no permanent damage was done before I found the causes of my problems!
