VIBRATION STARTING AT 42 MPH

1996 Lexus LS 400

Shakes or Wobbles problem
1996 Lexus LS 400 V8 Two Wheel Drive Automatic 155000 miles

My car start a harmonic type vibration around 42 mph and last thru 50 mph. It doesn't happen all the time about 90% of the time. Some times it can be felt/heard at higher speed. This vibration does not transfer to the steering wheel. What is best guess for cause(s) of this vibration.

Check ball joints and tires, balance, and or shifted belt in the tire(s).

I had a mechanic check this out and it turned out to be broken transmission mount. Since no one suggested this I would like my donation refunded

It is nice to have the beneifit of a lift and a look under the car, and yes sometimes it does take a bit of back and forth to answer ANY question, Ball joints, engine and tranny mounts are ALL possibilties, did you always take your ball and go home?
