I’m having a problem with extreme tail wiggle on my ‘14 2500. Just started with my last trip. I pull a 10k Fifth Wheel. The tail wiggle gets so bad the truck will loose traction and the traction control will kick in and reduce engine power. Very scary. My son has a ‘15 2500 so I moved the hitch and trailer to his truck and the problem went away. Has to be in the truck. My mechanic has checked control arms and bushings and suspension. Can’t findanything. Is it possible it is in the differential?Truck has 100k miles. Frustrated and no answers. Help anyone? TIA
