I have done lots of searching but this one still has me baffled. I have noticed a vibration/rumble when I'm in 5th gear around 2500 RPM, it feels like when shift into 4th or 5th at too low an RPM. The car runs soothe and shifts with no problems but if I cruise in 5th at a lower RPMs I have this problem, if I drive at the same RPM in 4th there is no Vibration. By the way, I did change my timing belt a few years ago but I don't recall having the problem after the belts was changed.

When my CVs were going, I found that about 62 MPH was where they caused a vibration. I noticed it in 5th first, but was able to duplicate it in 4th.
I ended up re-greasing and changing the rotation of my CVs, plus set of new bolts, and all has been well for a few thousand miles. Yes, replacing them would have been better.....but I was able to do that without any extra parts on a Saturday (I happened to have the bolts already).
