I am still having problems 3 years after purchase of my '19. I have an in-cab vibration at highway speeds. Been told a few times(at my expense) that it's within spec and perfectly normal. I'm trying once more to get it repaired or I'm seeking legal recourse. This is complete and utter ****ing ********!!!
New tires(the old tires had 13k miles on them) didn't help.
New driveshaft didn't help.
MULTIPLE balances (around 5 or 6) didn't help.
New brakes, didn't help.
Also, the truck also STILL has the clunk/thud when taking off from a complete stop.
