If a rear wheel weight came off or the rear tries are our of balance, you feel that in the drivers seat at about 68mph.
If the steering wheel shimy's at 68mph it the front tire balance.
A rear wheel bearing will make it sound like the manual tranny has a bad bearing. You need to listen very closely taking flyovers on the highway for the whine to move around the car to verify it's a rear wheel bearing.
A bad front wheel bearing will feel like the front tires are out of balance on different highways. When my fronts went bad, I would get the shimy at highway speeds on rt84 but not on rt91 here in CT. I now know what caused that. Took me a while to learn that lesson.
