my driveshaft now isn't broken, just with the 4.56 and 32's its spinning faster, and the slip yoke has some play in it, causing vibration. so i need a new driveshaft to fix the vibes, and carry the old as spare. i prefer to go new parts instead of the junkyard route. anyone have experience with either? warranties, quality? i can get the RE one for $30 cheaper, is the TW shaft worth the extra $30.
