T680 when empty has a vibration starting at @ 65 mph. This vibration is not constant and will come and go. I can have cruise on or using pedal and its shaking and i cancel cruise or let off pedal and shake goes away.
I have checked u joints and bearings and replaced center bearing. Have hade 3 axel alignment, all wheels balanced and have centramatics on 5 axels. These are Michelin tires with only 40k miles on them. The problem was there before the tires. Im pretty sure the problem is in driveline but not sure
Anyone have similar issue?
