Vibration , Sway Back and Forth
I have a 98 F150 4x4 4.6w auto with 216k miles.
Today I was driving 70 mph on interstate and a vibration started that shook the truck like a flat tire or ujoint. I pulled off and checked the tires nothing. I grab tire front and shook the truck nothing. I tried the same in the rear . I thought I felt some in and out tire motion on both sides. How much free space should there be ?
I drove it 40 miles back home I did not feel it. I think there is something wrong, not sure where to look .
