bobbyv and J. HIDALGO....thank you for your replies.....bobby, I live in London around 2 hours away from you where I have plenty of open road especially at 2 or 3 in the morning!!! J. HIDALGO, thanks for the tip on the rear end linkage. Anything could be possible so I will look into things when I have time. I know my tires are not the culprit, although they are worn somewhat, they are within specs and are balanced as I do not have that type of vibration at speed.
