What makes a truck vibrate at 70 miles per hour?
What makes a truck vibrate at 70 miles per hour? Truck vibrates at 70-75 miles per hour in the front end. Truck vibrates in front end at 70-75 miles per hour. Just driving does not vibrate when breaking. I have had the breaks checked and they are fine as well as had front aligned. What would cause this? Only vibrates it feels like in front end at this speed. I have had tires balanced and rotated. Is it possible to go 75 mph in 4 wheel drive? Damage might occur if you made a lot of sharp turns on dry...
