I've long suspected the pitch stopper and the tranny mount, but i cant quite orate why.
One of those gut feelings. I feel that the old axles had a lot of slop in them. As the motor mounts age, they get soft, sloppy, and may have actually failed (tranny mount).. SInce there is enough slop in the cv joints, this vibration does not get transmitted to the car, since the engine is essentially "floating" on its mounts. With one or two new axles, this slop is now gone, and it is the only part of the driveline that is not supported by rubber. (the rear axle is far enough away that it has no effect aside from an occasional clunk). Since the engine now has a tight (rigid) mechanical attachment, the engines vibrations can now be felt by the operator. It is more obvious with a manual, since the automatic is operated by a cable.
did that make sense?
