I was just wondering how to control vibration better on the highway. Do I need to replace the struts or bushings? The wheels are balanced well so I don't think it's a wheel balancing issue.
If it's in the seat it could be the rear wheels/suspension, if it's in the steering wheel it's often the front. It could be wind buffeting if it's only when the windows are open. Bushings=possible, struts=not fast vibrations like a wheel vibration.
Don't forget that a bent wheel can be balanced and still vibrate due to a dent. More clues? As axles wear down, they can sometimes make a little vibration.
You could try balancing the wheels again on a roadforce machine, these put the wheel on a roller to simulate the road. Ideally, any bends in the wheel will show up as a vibration.
I also hate wheel vibrations, a tricky area can be the axles, wear in them will produce vibration too but it's expensive to replace them.
I just replaced a bent/loose tensioner stud and it made a noticeable difference in vibrations. These weren't whole car vibrations but more like a resonance. It was causing a misaligned TB so you might want to pop off the cover and take a look.
