The old drive shafts suffer from internal failure [loosening] of the foam dampening material thus they cannot be rebalanced to spec.
There was a [center bearing support] change around 1993 resulting in longer life.
Without the newish pliable center rubber support the shaft sags and vibrations begin and get worse with age.
Never had any luck with used or rebalanced, thus always new unit to restore near new feel.......indexing required to select the correct phase alignment at highway speed.
My first one went at 120k, 183k on second unit, beginning to notice that replacement will soon be in order.
Lasting 7 years means the drive shaft only costs ~~$100 per year vs $400 for a transmission or $350 for an engine [over 15 years] for future replacement.....not maintenance.
Check with Ty at T3 [or Sports and imports] they might have some used but better condition {?}.
