A vibration felt through the center floor of the vehicle can be caused by driveshaft flex discs, which crack and shred, causing excessive driveshaft movement. Not repairing these can cause damage to the driveshaft center support bearing, or, in the worst case scenario, damage to the transmission or differential.

Trans leaking now
Slight vibration and loud noise like a rumble strip at 40 mph. Goes away if you back off the accelerator. Cracked front flex disc. Front and rear discs replaced with new parts. Car now runs fine.
