The dealer had it 2 days and said they couldn't find it so I got them in it. Showed it dronning - it's solid 60-75. So they ordered a drive shaft and replaced it. I took it on a 60 mile drive and it was gone. Coming back another 60 it happened a few times. Driving 65-70 each time. When mine drones it also gives a noticable vibration also. This was a week ago and I haven't driven it since. ed
Wonder if that's what I've experience since day one. That speed range is exactly where is starts coming in. It's a tight drone....almost like a cell phone vibration through the truck.
