While having my tires rotated and on the lift I usually do a driveline and under body inspection. What i noticed for the first time is some slop in the center drive shaft support bearing which I will need to replace. My question is can the flex disc's be reinstalled or must they be replaced. There were no signs of any cracking on either and with at least thirty thousand miles on them for sure as that is how long I have owned it so for sure more than that.
