You are well advised to avoid postponing this repair. The extra vibration could possibly damage a number of seals, bearings and bushings. You will have to drop the front of the driveshaft by removing the center bearing support sleeve (two capscrews). Exhaust may have to be moved out of the way as well. Not a difficult task, but requires some patience. Don't know if the newer flex discs have orientation arrows, take a look at what's there. This will only get worse. The time it takes to do so will depend on your driving habits..

No matter what you fix, there will always be something else to fix..
"Warranty" is just another way of postponing the inevitable.
