[TR] vibration

[Doug Mathews]

Gary,

Have you ruled out tires out of balance or out of line?  even with the 
engine off, they'd still could be the issue.

Does it happen once you reach a  certain speed?  Also, have you 
downshifted once the vibration starts to see if its related to engine speed?

I you speed up once the vibration starts does it change?

just some thoughts.

Doug

p.s. I seem to remember some comments about a vibration damper which I 
think was described similar to weight on the tail shaft.

Take a look at this:
