*letting off the gas does not necessarrily effect condition, it does decrease very very little due to unloading of rear end. I think this would be natural and not a true symptom of condition...
* Inspected rear end gears ( no issue ) and changed gear oil.
* Checked rims and tires, have changed tires and re balance no change.
* Have had engine and transmission rebuilt an new mounts ..No change, Note: Engine and trans rebuilt at different times ( 6 months apart) no change in condition at any point.
Have checked drive shaft run out and replaced u joints...No change.Drive shaft yoke nice and tight.
Torque converter, flexplate, harmonic balancer all replaced. no change
Running out of thing to change / replace .Anyone expirence this vibration issue ? It is a serious vibration not some hardly noticable harmonic vibration.
