It is not a driveshaft problem. Truck doesn't vibrate. On smooth roads it acts normal, but one bad spot on the road, and it starts shaking violently in the front end and sometimes it is so bad that you almost lose control.

I am going to check balljoints and wheel bearings tomorrow. I can't imagine that they would be bad unless these trucks are bigger piles of junk than I think.

Sorry fellow Ram owners, but the Cummins engine is the ONLY reason to buy one of these and unfortunately mine has the over-hyped Hemi.
