I put a 4.5 inch rough country lift in my 2017 f250 Diesel with 35 inch tires. It has a driveline vibration in the rear driveline line when accelerating when it hits around 55mph up to 70mph the harder the accelerate the worse it seems to be. It’s had shims put in, transfer case lowered 1/2 inch, all new u joints front and rear driveshaft, tires balanced and rebalanced nothing solves it. I can drive the truck 90 mph with no issues. The slip yoke is out about 3/4 inch more from the lift. It’s been to 3 shops and no one can seem to figure out what’s wrong. The last shop is blaming the tires but I don’t think they would cause to be worse during acceleration. Any help would be greatly appreciated. I’m concerned putting this lift in has ruined my truck.
