I had vibration at 35-45 and 73-80 did a level kit and body lift vibration stayed did bigger tires vibration stayed did new bilsteins level struts and another alignment and no more vibration at 73-80 and I rarely get a vibration at 35-45
I noticed the other day that when cruising at 75-80 while my truck is vibrating if I'm going around a bend the vibrating isn't as bad doesn't go completely away but def gets better when turning one way or the other I was thinking wheel bearings
I just bought a 14 crewcab 5.3 and have a vibration between 70-80 but it will get rough then will get lighter and keep going back and fourth its not constent anyone experience it??? I have 80k miles
