Why am I shaking
Hey guys/girls. I have recently been noticing some outside wear on my right front tire, so I had my tires rotated for a road trip over the weekend. Got driving down the interstate and noticed my 01 Excursion 7.3 L was shaking a whole lot. I felt it in the steering wheel a little bit, but anything over 68 mph, the entire truck was shaking. Then I went about 75 to pass a vehicle, and the truck was shaking so bad I hit the brakes and pulled over. I checked the lug nuts, and they were all tight. I then checked the tire pressures and they were way high, which I expected since it was pretty hot. I did let some air out of them just to see if it helped, and it made the slightest difference. Anybody have any ideas. Do you think I should just get the tires balanced and see if anything changes? Thanks, I need this thing ready for the rest of the trip.
