Many times the center support, transmission support, engine mounts, and diff bushings are all sagged simultaneously. Even 1/8" off will create vibrations and stress.
Like new requires all new, then trimming the center support with zero or 1-2 thin washers to minimize the accurately measured vibration frequency and amplitude.
Trying to return a 100k car to as new is always expensive and time consumming.
