First time I ever experienced it (before I started calling it DW) was a '67 Buick Wildcat. Great car. 40k miles when bought at 2 years old. About 10k miles later, a whole lotta shakin' going on!
Took it to a shop where the guy instantly narrowed it down to the right front tire with a bad internal belt or other internal failure.
Swapped it for a new one and away we went.
Another time was on an Early Bronco in '77, but no need to go into detail there I guess. Because it's a Ford!
I love that smiley dnuccio. Gotta get me some of them.
