1991 Ls400 Vibration?

[mrbig]

Tires have been balanced and aligned, feels like it could be coming from the drivetrain. Starting at 38 mph and continues as I accelerate but is not as obvious.

Any suggestion would be appreciated

Thanks

i had simular problems..changed alot of parts (1000$$$) ,turned out to be a) tires were causing it (got new ones) and b)the rear brake calipers eresiezed, causing the rotors to vibrate

[python]

rotors would only cause a vibration when u brake

Brakes were just replaced along with rotors.

If you do a search on the subject you will find many threads describing your problem as the Transmission mount the source of your issue, then eventually or at the same time change your engine mounts :)
