Probably wheel balance but you should have the front end safety checked for your own safety. You may have a tie rod end ready to separate and you would lose your steering, not good.
Check the wheel balance
possibilityThe car is out of alignment or you have a wheel out of balance.
If it happens when you are driving fast (60-70 MPH) it could be that your wheels are out of alignment.
You have a tire or tires out of balance.best to get tires road force balanced.
Tires may need to be balanced.
330 miles / 5.5 hours = 60 mph
It depends upon how long it travels for. Distance = speed * time So if the car travels at 60 mph for 2 hours, the distance is 60 mph * 2 hours = 120 miles But if the car travels at 60 mph for 30 minutes (0.5 hours), the distance is 60 mph * 0.5 hours = 30 miles.
ur car is slow
problem with your transmission in 5th gear
No, the energy of a moving car is proportional to the square of its speed. So, a car traveling at 60 mph carries four times the energy as the same car traveling at 30 mph.

My guess would be wheel balance.
