I was hoping that someone can help me diagnose a vibration in my '71 TR6.
It only becomes noticeable at 3500rpm+, and it feels like the same
amplitude/frequency that you would get from a very bad u-joint. I don't know
if this problem has occurred all-of-a-sudden or if I just started noticing it.
I'm sure it an engine vibration because if I let the car out of gear but keep
the engine revved at highway speeds, the vibration goes away.
Here's what I'm thinking so far:
exhaust system hitting the frame (unlikely)
a miss at higher rpm due to ??? ( I hope)
something loose in the engine (I hope not)
Could someone let me know what they think the most logical approach to solving
the problem is, or possible solutions?
Thanks in advance,
